Seeds

By Cheryl Harrison, Master Gardener

The excitement is building!  We have been dreaming while looking at seed catalogues.  Some have placed their orders and may have even received some product.  But, did you know that there are local events where you can purchase seeds from local growers and/or swap seeds with people who have  their own seeds saved from plants that they grew?  These events are often called “Seedy Saturday” or “Seedy Sunday”.   

The first Seedy Saturday event was held at the VanDusen Botanical Garden in Vancouver, British Columbia, in 1990.  Sharon Rempel had been trying to track down  flower and vegetable seeds for a heritage garden that she was trying to create at a museum in Keremeos, British Columbia.  She could only find what she needed at a Seed Foundation in Washington State.  Sharon wanted to bring together people who were interested in collecting and sharing seeds in British Columbia.  Sharon’s idea, of collecting and sharing seeds, has since become very popular across Canada.

Why are local seeds something to care about?  Seeds produced by locally grown crops/vegetables, flowers and trees, have been produced by plants that successfully grew under local growing conditions.  When we limit the variation in the plants we grow, we lose biodiversity.  Biodiversity is so important because  it ensures that there is genetic diversity which means that the plants have the traits necessary for local growing conditions.  Local seed production can result in new varieties of plants that are more resistant to disease and local pests and better able to adapt to local soils and environmental conditions.  With enough variation in a group, there will always be individuals that can survive changing conditions…..so necessary in today’s world.

Local seeds are often heirloom, or heritage and openly pollinated which means that if you save seeds from these plants, they will grow true to the parent plant.  The other big bonus is that vegetables, grown from these seeds, are often tastier and more nutritious.  For more information, see this Mother Earth News article HERE.

So, back to your local Seedy Saturday or Seedy Sunday….these events are fun!  There is great excitement and bustle as attendees talk about what seeds they have to swap and as they look at the seeds offered by various local vendors.  Workshops and “Ask the Expert – Q & A” are often offered.  Sometimes there is even something to get your really young gardeners off to a good start eg. growing sunflowers.  This year I hope to track down musk melon seeds that will be sweet and ripen quickly in my area.  My grandmother used to grow the best musk melons ever!

This year, Covid 19 remains something that we have to contend with….many Seedy Saturdays and Seedy Sundays have gone virtual!  Check out Seeds of Diversity  HERE for an event near you.  The Peterborough Seedy Sunday is on March 14.  Check out their Facebook page HERE for more details.

If you have not checked out a Seedy Saturday or Seedy Sunday before, have a look virtually this year.  You might discover a delicious new-to-you variety of your favourite vegetable or learn something amazing at a workshop!

Low Growing Natives for Lawn Replacement

By Sharleen Pratt, Master Gardener

I recently listened to a talk by Lorraine Johnson who is the former president of the North American Native Plant Society and is the author of numerous books on gardening and environmental issues. I was inspired by her talk and have started plans to turn part of my front lawn into a native garden.

I have struggled for years to grow grass near the bottom of our front yard.  The soil is mostly clay with a lot of rock.  We have no sidewalks and this part of the lawn sits at the curbside where it could be affected in the winter by salt and sand.  It faces north/west and receives a very hot sun, especially in the afternoon.

I am not a regional native plant purist.  I get excited about most plants and have a variety of perennials in my gardens.  I am hoping to fill this garden bed with as many native plants as possible, but I do recognize that some of the plant varieties are not always considered native.

There are a number of lovely native plants for sun that have height, but I am cognizant of the fact that my neighbour requires a safe line of sight to the street when they come down their driveway.  For this reason I would like to use mostly low growing groundcover with a few taller plants positioned in areas that will give a pleasing look to the garden bed, but also not impede on visibility.

I have begun to research native groundcovers and other low growing plants that would survive in the conditions I’ve described and here is what I have found so far.  Some of these are new to me, but others are plants I already have in my backyard.

Have you considered replacing part of your lawn?  I would love to hear about your ideas and your successes and failures.

Bearberry (Kinnikinnick) Arctostaphylos uva-ursi

This plant grows 6 to 8” tall and has a spread of approximately 3 feet and is similar to a low growing shrub.  It has a white bloom with a tinge of pink in May.  It’s drought tolerant once it’s established. Rounded berry-like fruits ripen in August to September.  Birds love the fruit!  I have a friend who has found that this plant will disappear over time and because it prefers a sandier soil, it may not be the perfect plant for my home.  However, I may give it a try as I occasionally enjoy pushing the limits.

Creeping Juniper, Juniper horizontalis ‘Wiltonii’

This plant is known to be salt tolerant, likes sandy soil and full sun, grows to a height of 8” and spreads to approximately 7 ft.  It is a non-flowering evergreen.  It spreads by long trailing branches. Foliage is primarily scale-like (adult) with some awl/needle-like (juvenile) needles appearing usually in opposite pairs. Foliage is typically green to blue-green during the growing season, but often acquires purple tones in winter. It likes to grow over rocks; however, it is a slow grower and takes some time to get established. 

Prairie Smoke, Geum triflorum

Prairie Smoke; Author’s garden

This is a tough plant, and grows to about 6 – 12 inches.  It has a lovely reddish pink to purple bloom with interesting seed heads.  It is drought tolerant.  My one concern is the hot afternoon sun, as my research shows it may prefer a bit of shade later in the day.  As the flower fades and the seeds begin to form, the styles elongate (to 2″ long) to form upright, feathery gray tails which collectively resemble a plume or feather duster.  They are very unique.  It spreads by rhizomes and can be naturalized to form an interesting groundcover.

Small Pussytoes, Antennaria howelli

It has spoon-shaped basal leaves, is known to be drought tolerant, and has flower heads that look like little shaving brushes.  There are three to 15 flower heads in a flat to rounded cluster at the top of the stem. Stems are erect, green to reddish, covered in long, white, matted hairs and sometimes glandular hairs. Horizontal, above ground stems (stolons) emerge from basal leaf clumps, spreading in all directions, rooting at the nodes and forming colonies.

Pasque Flower, Anemone patens or sometimes Pulsatilla vulgaris

Pasque Flower; Author’s garden

Pasque flower grows up to 12 inches tall and forms a rounded clump, which increases yearly. It never gets out of hand, making it a desirable plant.  It carries one flower with purple petals and yellow stamens, on top of each stem.  The bloom is quite large, up to 2 inches in relation to the overall size of the plant.  It is not fussy about soil conditions, but may go dormant during drought.  It blooms in late spring into summer.

Nodding Wild Onion, Allium cernuum

My research shows this is a very pretty plant that grows to a height of 1 to 2 feet.  It blooms in mid-summer.  Its grass-like ribbony leaves are long and graceful; its flower cluster hangs down, covered with a fine onion-skin-like sheath before opening.  The blooms in mid-summer are whitish rose coloured and bell-shaped.  The seed heads are round.  It does prefer good drainage.  Looks best when planted in groups.

Butterfly Weed, Asclepias tuberosa

Butterfly Weed with Zinnias; Author’s garden

This is a butterfly magnet that has clusters of orange flowers borne at the top of 2-to-3-foot stems.  It is probably a little larger than I would like, but thought I might give it a try in the front.  This image is from my garden 3 years ago.  I lost the plant the next year and believe it was because of overcrowding and not enough sun.  The leaves are narrow and dark green.  The plants get bushy if they have lots of room.  The seed pods are large and very striking.  They bloom in mid-summer and prefer a full sun exposure.  Once established, they are drought tolerant.  It emerges from the soil quite late in spring, so it is important to be careful not to disturb the roots.

virtual garden tours

Exploring gardens around the world makes the winter pass so much faster

By Emma Murphy, Master Gardener

I have the February blahs. Although I am absorbing each minute of our ever increasing daylight (when it’s not cloudy!), I’m craving lush greenery and blooms anywhere I can find them. I spent part of yesterday looking through some trip photos to Florida from 3 years ago where I visited just about every botanical garden and specialty garden I could find – it was heaven!

And while my seed orders have arrived from William Dam Seeds and Richters and I can look forward to some sort of virtual Peterborough Seedy Sunday, the traveller is me is still feeling unfulfilled.

So..the solution..virtual garden tours! So many wonderful botanical and famous gardens have adapted to not being able to have guests by launching virtual tours or live broadcasts from their locations since the pandemic. Here’s a few of my favourites.

Time to travel around the world from your living room. (additional links at the end).

Keukenhof, The Netherlands

Built in 1641, the Keukenhof Castle (west of Amsterdam in the Netherlands) and estate is more than 200 hectares. In 1949 a group of 20 leading flower bulb growers and exporters decided to use the estate to exhibit spring-flowering bulbs. 2021 will be the 72th edition of Keukenhof, with A World Of Colours as its theme. Check out their virtual tours and the initial invitation by Managing Director Bart Siemerink in March 2020.

The Keukenhof Gardens in full colour.

Claude Monet’s Garden, Giverny, France

Over 500,000 people visit painter Claude Monet’s famous gardens each year (so glad to be one of them in 2018!). There are two parts to the garden – the Clos Normand flower garden in front of the house and a Japanese inspired water garden on the other side of the road (where he completed his Water Lilies painting series). Enjoy a commentary alongside a video tour of the famous garden, including the wonderful lily pond. More info here.

Monet’s Water Garden

National Trust’s Hidcote Manor Gardens, England

The National Trust site allows you to take a 360-degree tour around the old garden, plant house and spectacular red borders of these Arts and Crafts-inspired gardens in the rolling Cotswold hills in Gloucestershire.

Hidcote Gardens

Scotland’s Garden Scheme

One of my favourites. Established in 1931, it helps garden owners across the country open their private gardens to the public to raise money for charity. The properties range from cottage gardens to stately homes; allotments to therapeutic and physic gardens; and formal gardens to wildlife sanctuaries. There are more than 100 tours to look at here.

A Scottish country garden.

Australia’s Blue Mountains, New South Wales

Further afield in Australia’s Blue Mountains just outside Sydney, artist Trisk Oktober’s steep, cool temperate gardens in Katoomba are transformed into a living artwork. I visited the nearby Mount Tomah Botanic Gardens in 2010 and it was magical. It’s also the only botanic garden within a United Nations World Heritage Area.

The view from Mount Tomah Botanic Gardens of the Blue Mountains

Hawaii Tropical Botanical Garden, Hawaii

Located on Hawaii’s Big Island, the Hawaii Tropical Botanical Garden includes not only a garden but a nature preserve. If you need to zen out and feel like you are on a tropical island, this is the tour for you. And this one.

Plumeria flower

Longwood Gardens, Pennsylvania, USA

Closer to home across the border is Longwood Gardens, consisting of 1,077 acres of gardens, woodlands, and meadows. It is the living legacy of American entrepreneur and businessman Pierre du Pont, inspiring people through excellence in garden design, horticulture, education, and the arts. The Our Gardens, Your Home initiative is their way of keeping gardeners connected.

Longwood Gardens

There are so many more virtual garden tours going on around the world.

Lewis Ginter Botanical Garden, Richmond, Virginia, USA

This botanical garden was one of the first to go virtual when the pandemic started. They have great virtual tours and visits and a terrific Facebook page.

Gardens Illustrated‘s Virtual Garden Tour series

Gardens Illustrated has assembled a collection of some of the most amazing tours – everything from Chatsworth House (a 105-acre garden with 500 years of careful cultivation) to a Virtual Chelsea Flower Show.

Kew Gardens, London, England

On my bucket list when we can travel again, this video gives you some of the highlights to see. The Royal Botanic Gardens at Kew has 37 acres of woodland, 14,000 trees and 50,000 different plant species.

Wisley Gardens, Surrey, England

The Royal Horticultural Society’s garden at Wisley in Surrey (south of London), is one of five gardens run by the Society, and top of my list of gardens to see. Check out their website, and also they have a great collection of videos on YouTube.

If you’ve found a great virtual garden tour please share it with all of us in the comments! Spring will be here soon!

In Praise of Sunflowers

By Mary-Jane Pilgrim, Master Gardener

The weather outside at this time of year is a bit frightful, so as a diversion, let’s vault ourselves temporarily into mid-summer and learn about that giant of summer flowers — the sunflower. In all their colourful glory, these plants are a happy sight to behold—but there’s more to their nature than just beauty. The multipurpose plants deliver healthy snacks for us, useful oils, and seeds for our feathered friends.

Sunflowers are members of the family Asteraceae, which all form a composite head (capitulum) made of masses of simple flowers (florets) that each produce a seed if successfully pollinated. Sunflowers typically have between 1,000 to 1,400 florets, and potential seeds, per head. The capitulum is surrounded by petals, making the whole structure seem like one single flower. The latin name for the common sunflower is Helianthus.

Butterflies, beneficial insects, hummingbirds and birds flock to sunflower heads for food, pollen and nectar. Insects enjoy the flower pollen and nectar while birds feast on the seeds. Plant tall varieties along a fence to block an unsightly view, or try them in the back of the flower border or along the side of the house or garage. You can also use sunflowers instead of corn in a Native American ‘Three Sister’s Garden’: Plant pole beans to grow up the clump of 3-week old sunflower stalks, and plant winter squash and pumpkins around the base of the clump 3 weeks after the beans. The beans will climb up the flowers and the low-growing squash will shade out weeds and prevent the soil from drying out.

The flowers not only look like the sun; they need a lot of it. They grow best with about six to eight hours a day but more is even better. They can grow as tall as 16 feet, although many varieties have been developed to thrive at different heights. Flowers planted too close together will compete and not blossom to their full potential.

Sunflowers display a behavior called heliotropism when they are young–the flower buds and blossoms will face east in the morning and follow the sun as the earth moves during the day. However, as the flowers get heavier during seed production, the stems will stiffen and the mature flower heads will generally remain facing east.

Although sunflowers can be started indoors in individual peat pots, it is easiest to sow seeds directly into the soil after all danger of spring frost is past. However, where the growing season is short, sunflowers can be safely planted up to 2 weeks before the last expected spring frost.

Winter Bird Treats

By Lois Scott, Master Gardener

I have been fortunate this winter to have the ability and opportunity to carry on with regular, ‘socially distanced’ walks in my neighbourhood and to be able to enjoy the winter interest provided by nature. 

On several walks I was quite excited to see small flocks of Pine Grosbeaks and Cedar Waxwings feeding on ornamental crabapple trees (Malus species) in two neighbouring gardens that I pass by.  For me it was a special treat to see Pine Grosbeaks, as they are a somewhat irregular winter visitor to the Kawarthas.  Their breeding range is in the boreal forest and, according to Drew Monkman, if there is food they stay put. If not they travel south where you may see them on feeders or fruit trees, such as crabapples.  

Crabapples, typically planted for their flowers, produce colourful fruit that is not only attractive in winter but a potential source of food for birds.  In choosing a variety to plant, Landscape Ontario recommends considering resistance to disease and insects, and fruit persistence, which is important for feeding the birds as the crabapples need to stay on the tree. Another noteworthy fact is that birds can be picky eaters and in their estimation apparently not all crabapples are created equal.  For example they like ‘Prairiefire’ whereas they do not like ‘Adams’, ‘Donald Wyman’ or ‘Red Jewel’.  Who knew!  I don’t know what the varieties are of the two different trees I saw birds in but the tree in the first photograph shows the tree fairly well stripped of fruit. In the second photo there is still plenty of fruit that they have not come back to finish. 

Crabapple trees in the author’s neighbourhood

There are other excellent choices of native trees and shrubs that can provide winter food sources for birds.  The hackberry (Celtis occidentalis), a shade tree that works well in ‘difficult’ urban areas, hawthorns (Crataegus species), highbush cranberry (Viburnum trilobum), and red chokeberry (Aronia arbutifolia) are a few good choices. 

For a more comprehensive list of crabapple varieties and other native species to feed the birds in winter please check out the following links.

Year in Review, Part II

By Suzanne Seryck, Master Gardener

I wrote the first part of this two-part blog on a beautiful fall day, with a temperature of around 20 degrees and blue skies. Today as I’m writing it is the type of winter day that I love, temperature hovering around zero, snow on the ground and I don’t need 4 or 5 layers of clothes on when I go out for a walk. The first part of my year in review blog that was published back in November described some of the many challenges and learning experiences I faced gardening in 2020, including growing Sicilian zucchinis, handling Creeping Charlie in my lawn, and becoming more selective when deadheading. In this second section I’ll continue on with the challenges, including staking perennials, trying to grow an English cucumber and battling with the wildlife over the grapes, blueberries and currants.  

Now I have to admit before I start, that staking is not really my thing; it typically needs planning and thinking ahead. You can stake reactively as I tend to do, but by then it is often too late; the plants still look untidy, flop over adjacent plants and you can see the stakes, which for me personally is an issue. Last spring my iris, lupins and especially peonies grew so tall so quickly that they easily outgrew the old peony cages that surrounded them.  My fall asters also fell over as they hadn’t been staked at all and were easily over six feet tall. So this spring I need to be more preventative and stake as early as I can. There are many different types of stakes that you can use such as grow-through supports as in peony cages or tomato cages. These work well if the plants are not too tall, although I do have some of the larger tomato cages in my garden. Grid-type supports also work well for plants that bloom heavily, and for irises I tend to use single stakes that I can just move around the garden as needed. You can also make your own supports using bamboo stakes or tree branches and twine or even chicken wire. Most gardening catalogues, such as Veseys or Lee Valley sell plant supports in many styles. For me however, I tend to find them quite expensive and tend to work with tomato cages or make my own.  For more information please see the following article: https://www.bhg.com/gardening/flowers/perennials/staking-and-training-perennials/

English cucumbers, what can I say, I still tend to prefer these over other varieties that definitely grow much better here. English cucumbers tend to be longer, thinner, with an edible skin and in my opinion taste better. They do not however like cold temperatures, so if planting in the garden ensure that all danger of frost has long passed, and in fact, wait a further week or two after that. They also have shallow roots so need more frequent watering. I also find that for me they grow stronger and healthier if I provide some type of shade when it gets really hot. English cucumbers will also grow straighter and longer if the fruit can hang, so growing on a vertical support works really well. However, after saying all that, I still am unable to grow them as well as I would like and they are definitely very labour-intensive. So for this year, I am going to grow a different variety, although in saying that I have not tried growing cucumbers in containers, so that might be an option to try. Greta’s Organic Gardens have some interesting cucumber varieties for seed purchase, including Crystal Apple Cucumber that is shaped like an apple when mature, a Miniature White Cucumber which needs no peeling and is eaten when smaller than 3 inches. Lastly a Spacemaster Picking Cucumber that can be grown in either a container or a hanging basket. This company is one of many Organic seed companies based in Ontario. https://www.seeds-organic.com/pages/contact-us

And last but not least, one of my favourite subjects last year in the garden was the wildlife, namely the dreaded squirrels and rabbits. We have a few different structures that we have built to keep out the animals, including:

And:

Not to mention:

This last picture shows simple plant trays with a mesh bottom lying upside down over new seedlings. I use these both to deter the animals and also to help keep the seedlings shady. However, none of these prevented the squirrels from taking bites out of most of my tomatoes, eating all my grapes, of which we had a bountiful crop, and the birds from eating my blueberries and white currants. The previous year I had put nets over the blueberries and currants which had helped, however since then I have read a few articles stating that the types of netting I was using could damage both birds and other wildlife so I was reluctant to put it on again. I have since done more research but not found anything yet suitable for my needs. However it is only January and will likely get a lot colder, which gives me plenty of time to do more investigation and come up with something suitable.

My covid-19 project for 2021 — starting a cutting garden

By Marilyn Homewood, Master Gardener in Training

Last October as I planted the last of my fall bulbs, my thoughts turned to what next???  How to extend my garden experience by stretching the season.  I adore flowers in the house and between retirement and lockdowns seem to have the time so why not try a cutting garden?

Used with permission from antoniovalenteflowers.com

I have no experience with the subject matter and it made sense to find some resources.  A good comprehensive book is “Floret Farms Cut Flower Garden” by Erin Benzakein.  It covers the basics of cut flower gardening as well as highlighting tips for commonly grown flowers.  How to plan, grow, harvest and even some basics on arranging.  This book proved to be a doorway into a plethora of other references and websites on the subject.  “YouTube” was also a plentiful source of information.

Site selection is key.  Most cutting flowers require full sun and well drained, fertile soil.  A site sheltered from the wind is preferable.  I decided on an area on the west side of the house where the sunshine is ample and my water source is nearby.  Since it will be windy, the support provided to the plants is important and will be discussed in future entries. The final length of a bed will depend on the amount you want to grow. The recommended width is 4 feet. This width allows you to reach the entire bed without stepping into the bed.  The type of flowers to grow is personal preference but regardless of the variety, look for plants with long stems and lots of blooms.  Try to have plants that bloom in the spring (eg. snapdragons), summer (eg. zinnias) and fall (eg. dahlias).  If space is limited, skip the plants that bloom once (like many sunflowers) and concentrate on continual bloomers such as zinnia and dahlias.  These are known as “cut and come again varieties” as they provide blooms for long periods if they are cut or deadheaded. You may also wish to grow some plants as fillers such as Dara.  Fillers are the backbone of arrangements, lending structure, supporting delicate blooms and filling gaps between focal flowers.

Dara filler used with permission from antoniovalenteflowers.com

Cut flowers are grown more densely than usual and most commonly are spaced 6,9 or 12 inches apart.  References abound on the internet indicating which spacing is best for each variety.  The number of seedlings, corms or tubers required is calculated using the area available for that plant and the spacing distance.  Once calculated, order your seeds as soon as you can.  Goods for the garden seem to sell out quickly in these days of lockdown. Seed vendors have been discussed in a previous blog.  In addition to those already cited, many of the cut flower farmers also sell seed. 

Once you have selected your seed, you then need to determine when to start them indoors using the last spring frost date for your area (OMAFRA lists Peterborough as May 17).  For each variety, check the seed package for timing and work backwards from there.  This allows you to make a seed starting schedule.  For those seeds you intend to direct seed, you may need to consider time to maturity in order to give the plants time to bloom (work backwards from first frost date in your area).  I make a list of seed sowing dates to help keep me organized.

Now all there is to do is wait for the seeds to arrive.  I start sowing in February.  Please join me through this blog on my horticultural adventure.

To plant a garden is to believe in tomorrow” Audrey Hepburn

Gardening with Ferns

By Cheryl Harrison, Master Gardener

Ferns are fascinating plants! They evolved more than 350 million years ago. Ferns and their allies were the most common plants during prehistoric times. Today, there are over 12,000 fern species growing everywhere except at the poles.

Ferns are special in the gardening world. They are exotic and beautiful but not as flamboyant as many plants. We have developed a fern “dictionary” to describe them. For example, an entire fern leaf is actually called a frond and the stem is called a stipe. Ferns reproduce via spores which are not the same as seeds and ferns do not produce flowers. If you study ferns, you may be a pteridologist….oh my!

Fern propagation means collecting spores or bulblets. Fern propagation, using spores or bulblets, is explained here . There is only one native Ontario fern that produces bulblets. It is the bulblet fern or Cystopteris bulbifera. The easiest way to obtain a new fern is, of course, to buy one. A list of local vendors is below. Some ferns spread via rhizomes or underground runners, just split the root with a sharp shovel and separate out the fronds of the new plant. You may also split ferns with fibrous roots as you would many perennials, once they reach an adequate size, again using a sharp shovel. You may split then plant ferns in the spring or fall. Check out your friend’s gardens…you may find a fern, or two, growing that your friend may be willing to share. Please do not harvest from the wild. Some fern species no longer grow in the wild because of over harvesting.

Maidenhair fern (Adiantum pedatum), Author’s garden

Ferns may be used in your garden as an exclamation point or a secret quiet spot, mixed in with your other shade loving perennials or in a woodland garden. I have some ferns mixed in my gardens now but 2021 is the year that I plan to tackle the creation of a woodland garden. I have already put in an order for some ferns including the bulblet fern (Cystopteris bulbifera), ghost fern (Athyrium X Ghost) and the ostrich fern (Matteuccia struthiopteris). This grouping should work well together because they all prefer shade or part sun and moist soil with lots of organic matter. I plan to amend their location with compost and to mulch after planting to maintain moisture and reduce weeds. These plants are perennials so I will expect to see them again next year.

Ferns are beautiful plants whose graceful, arching fronds would make a great addition to your garden!

Planning for pollinators

by Rachel Burrows, Master Gardener

Did you know that pollinators are responsible for pollinating over 30% of the foods that we eat? Many pollinator species are at risk due to climate change, habitat loss, and pesticide exposure.

So, what are pollinators and what do they do? Bees and other insects, butterflies, moths, hummingbirds and other small birds all need a constant source of food from early spring through to fall. They are looking for pollen-bearing flowers with fairly easy collection of nectar and pollen.

How can we help? There are many ways that we can help in our own gardens. We can provide habitat for pollinator birds and insects by installing nesting boxes both for birds and cavity nesting bees. Fallen trees and an area of bare ground will provide access for ground nesting bees and butterflies. Pollinators really prefer a little less manicured garden!

A pollinator hotel, although brush and logs on the ground are just as good. It’s important to keep in mind that these hotels require regular upkeep. Because they host pollinators at a higher density than a natural nesting site, disease and pathogens can quickly spread among visitors.

Water is another necessity and a shallow container with a couple of small rocks in it is the perfect drinking spot. Try to avoid chemical fertilizers and use compost instead which is better for both your plants and the pollinators.

What plants to choose – plant native when ever possible. Native plants have co-evolved with pollinator species and are well adapted to our local conditions. Pollinators can more easily access single bloom flowers such as echinacea and asters as their stamens and pollen are more exposed. Plant species in clumps to provide a target for pollinators, bees tend to gather pollen from one type of plant at a time. Provide host plants as butterflies such as the Monarch, lay their eggs on specific plants for their caterpillars to feed on. In the Monarchs case milkweeds are the only plant that they will feed on.

Try to have plants to provide four season interest, this can include grasses as they will provide shelter and food. Aim for at least three different species of plants blooming in each of the growing seasons. Study your site to determine the amount of sun and wind exposure and how much water will the plants receive?

Pollinators locate their food sources by sight and smell and the bees will go crazy around plants such as lavender and anise hyssop. Honey bees love white, yellow, blue and purple flowers.

The Peterborough Master Gardeners in conjunction with the City of Peterborough and the Ontario Federation of Anglers and Hunters have installed a pollinator garden with all native species at the McNamara Park. This is a City owned park on McNamara Rd. which runs off Guthrie Drive and along the Otonabee River across from the OFAH building. It is a very peaceful park with many trees and seating areas. It is well worth a visit and may give you further ideas for helping our pollinators in your own garden. You can make a difference!

Winter, when a gardener’s thoughts turn to Spring

By Emma Murphy, Master Gardener

So now it’s wintertime. Our plants are sleeping quietly beneath a bed of wonderful white snow, and although we hibernate and rest to a degree, a gardener’s thoughts turn to springtime. I’m exploring some new ideas for my gardens for next spring, and thought I would share them with you.

No I didn’t get a greenhouse for Christmas…yet.

RAISED BEDS FOR GARDENING

But I do have a wonderful husband who knows how to make his wife – the Master Gardener – a happy person. His Christmas 2020 gift to me was to create some raised beds so we will be doing that this spring. I have been wanting to do raised beds for a few years since seeing Tara Nolan do a presentation at the Peterborough Garden Show, and I guess dropping those significant hints finally worked 😉

So we did a little research. Have you been thinking of creating raised beds for either vegetable or other gardening? They are great to extend the gardening season, be able to control soil quality, provide accessibility for older gardeners or those with disabilities, create a garden for special purposes (youngsters or horticultural therapy), increase yields, reduce weeds, and keep critters at bay. They also work well for condos and rooftops in our urban centres. Here’s some great sites I found for those interested in the idea.

One of my favourite gardeners with a similar climate to mine in Central Ontario – Erin Schanen in Southeastern Wisconsin (zone 5) – The Impatient Gardener. She has several good articles on growing in raised beds, from layout through to construction.

Tara Nolan’s book Raised Bed Revolution emerged at a time when this idea was gaining a lot of traction, and it’s an excellent source of information on size requirements for constructing raised beds, height suggestions, types of materials you can use, and creative tips for fitting the maximum garden capacity into small spaces—including vertical gardening. The Toronto Botanical Garden also wrote a great review. We also have a copy of Mel Bartholomew’s Square Foot Gardening, which focuses on growing more fresh produce in less space, and is very complementary to the raised bed philosophy.

For some general information on raised beds try here and here.

ORDERING YOUR SEEDS

Maybe it was just the crazy rush (and delay on delivery) for seeds this past spring, but we just ordered our vegetable and flower seeds for the 2021 season. There are lots of seed companies to choose from, but please try to shop from Canadian companies and especially those local to you. Although COVID-19 meant the cancellation of Peterborough’s wonderful Seedy Sunday, the organizers did post a list of all the vendors who would have been there, and it’s a great resource, as is the Seeds of Diversity site.

ESPALIERED FRUIT TREES

Espaliered fruit trees (espalier – to train a tree or shrub to grow flat against a support or wall) have been on my garden wish list for several years, and I missed an opportunity to pick up a mixed apple espalier tree several years ago which I have been kicking myself for ever since. I saw amazing espaliered fruit (English style) in the Victorian Kitchen Garden at Meadow View Gardens (just north of Cobourg) on a Master Gardener tour several years ago, and was entranced (well I’m entranced by owners Julie and Garry Edwards’ entire English-inspired gardens, but that’s another story).  

Although they can be any kind of fruit they are most often apples, and the key to doing it well is understanding how to prune the trees. Garden Therapy has an excellent article on how to grow these edible gardens, in ways that can accommodate both small spaces but be decorative. There are many different shapes that can be done – cordon (branches straight out to the sides), fan (branches fanning up and to the side), candelabra (like a cordon but the branches turn at a right angle to form the shape of a candelabra), lattice (multiple trees with crossing branches), and “Y” shapes. Maybe this is something you can try in your garden as well? The Ontario Ministry of Agriculture, Food and Rural Affairs (OMAFRA) has a list of nut and fruit tree nurseries. I know one company I have dealt with is Silver Creek Nurseries in Wellesley, who specialize in fruit trees, and they offer the following advice on their website:

“Spur bearing varieties are recommended (rather than tip bearing), such as Cox’s Orange Pippin, Winesap, Fuji, Belle de Boskoop, Calville Blanc, Sweet 16 and many more. Apple and pears are generally the easiest fruits to train, but other species may be espaliered with varying degrees of difficulty.”

Grow a Little Fruit Tree: Simple Pruning Techniques for Small-Space, Easy-Harvest Fruit Trees is also recommended as a resource (although I haven’t read it).

I’ll be in touch with them once spring rolls around, which should be in 82 days or so (but who’s counting?). Enjoy your winter garden dreaming, and spring will be here soon enough.
