Beware the Vigorous Plant!

1 Comment

By Suzanne Seryck, Master Gardener

Being the fairly recent owner of a small city garden, I find I no longer have the space for plants that either do not behave, need too much deadheading or pruning, spread too quickly becoming invasive, need to be staked or I’ve simply grown tired of. At least 90% of my garden is full of either fruit trees, shrubs, fruit bushes, perennials or raised vegetable beds. The remaining 10 or so percent contains a patio and a very, very small lawn that my husband tells me has to stay! So needless to say if I buy any new plants I have to give an existing plant or two away (thank heavens for plant sales).

I have a few plants in mind that I am considering replacing this spring so I have spent the last week or so looking through bulb and plant catalogues to see what is new this year. Catalogues are a great place to see what is new and exciting and also to fill the gardening void that generally happens this time of the year. However, I have heard both good and bad stories regarding plants purchased from these catalogues, so it is very much a personal choice. What I did notice though were the many different terms given to what I would describe as an invasive or ‘buyer beware’ plant, especially if, like me, you do not have a large garden.

allium

Allium were described as ‘carefree’. However, if you have ever tried removing hundreds of allium bulbs from a perennial bed that have self-seeded over many years ‘carefree’ is not a term I would immediately think of.

‘Vigorous’ is a term often used in these catalogues, which could mean either that the plant is strong, robust and grows well (which we would all like) or more likely that the plant grows very quickly and will take over your entire garden in a very short time. Examples of ‘vigorous’ plants include false sunflower (Heliopsis helianthoides), knotweeds (Persicaria) and orange trumpet vine (Campsis radicans).

Baby’s breath (Gypsophila) is listed with the description that it ‘readily fills gaps’, whereas bee balm (Monarda) is described as ‘multiplying quickly’.

lily-14254_1280

Lily of the valley (Convallaria majalis), need I say more! I actually inherited this plant in my shade garden and I think I could be digging it out for a good few years. I really do love this plant, but it has to be in the right location and in a bed all by itself. Lily of the valley is described in one catalogue as ‘creating a carpet of flowers’ and in another catalogue as ‘growing fearlessly among tree roots’.

But I think the term most often used to describe a plant that might become invasive in these catalogues is ‘naturalizing’. When I think of naturalizing I think of beds or daffodils or bluebells, but then I am English so that might explain why. Plants included in this category are masterworts (Astrantia), mountain fleece (Persicaria amplexicaulis), false sunflower (Heliopsis helianthoides) and meadow rue (Thalictrum flavum).

Being an avid gardener, some may even say obsessive, there are not many plants that I do not like and all of the plants listed above I have at one time or another grown, and still do. But gardening with only a limited amount of space has changed the way I look at and select plants.

By Mary-Jane Pilgrim, Master Gardener

Gardening is supposed to be natural, right? Many who enjoy the outdoors and gardening downplay screens and technology and also tend to encourage others to put down the devices and experience what’s in front of them. But what if you don’t know anything about what IS in front of you? Your smart phone or tablet can be quite the gardening companion.

Here’s a selection of apps that can be found in the App Store that will help you know when/where/what to plant, and sometimes more importantly, how to find out what’s already growing in your yard or someone else’s that you admire.

LeafSnap: An Electronic Field Guide — Free (iPhone only)

How many times have you been in a public park or garden and fell in love with the trees, but with no one to ask what they are?  Using visual recognition software, Leafsnap can identify trees from a photo of their leaves alone. I can’t tell you how many times I could have used this!

myGardenAnswers Plant Identifier — Free (iPhone/Android)

With Garden Answers Plant Identifier, you can take a picture of a plant that you want to identify and presto — you’ll get its name and all of the information about it. It’s like having an encyclopedia in your pocket. This is easily one of the best free gardening apps in existence, namely because it can automatically recognize more than 20,000 plants. This app also identifies pests and has a robust Q&A section that covers more than 200,000 of the most common gardening queries.

GrowIt!: Garden Socially — Free (iPhone/Android)

GrowIt allows you to join an enthusiastic community of gardeners, helping you to find inspiration, gather information, and share your own gardens with the world. This app is good if you want to find out what plants will grow well in your local area.  As you find plants you love in their extensive database, you can organize them into projects to help you design your own green masterpiece.

Garden Seminars & Workshops: Every Gardener’s Should-Do List

4 Comments

By Lee Edwards, Master Gardener

As Gardeners, we already know that gardening has many benefits including improving our health and connecting us with nature, to name just a few.  That said, did you know that attending gardening seminars and workshops can also improve your health- brain gain, ramp up your gardening skills, get you out meeting others with similar interests, and increase your communication abilities?  Even more, seminars and workshops add new ideas to your horticultural know-how, empower your confidence in gardening, and help to propel you to new gardening heights.

So, what does a gardening seminar or workshop look like?  Well, unlike lectures, they tend to be short, interesting, educational talks or demonstrations usually featuring a speaker engaged with a small group of attendees focused on garden topics of interest to the attendees.  During the event attendees typically get the opportunity to ask questions, participate in hands-on activities if any, learn something new, connect with speakers and increase their existing knowledge.

Indeed, during the cold winter as outdoor gardening slows down, attending a garden seminar or workshop is a great way to break up the long winter months away from the garden while remaining involved in garden goings-on and being amongst gardening enthusiasts.  The lively energy and creative atmosphere that permeates these events are infectious to everyone, worth the time and fee to attend, not to mention downright fun most-times.  Truly, garden seminars and workshops should be on every gardener’s yearly to-do list.  If you’ve never been to a garden seminar or workshop, now may be the time to try one, to investment in yourself, inspire your creative growth and add to your gardening knowledge.

Did you know that the Peterborough & Area Master Gardeners annually present a wonderfully fun and informative gardening seminar called “A Day for Gardeners?”

What to Get a Gardener who has Everything For Christmas

Leave a comment

by Suzanne Seryck, Master Gardener

Generally on the whole gardeners are a pretty easy bunch of people to get Christmas presents for – who doesn’t love a good ‘garden themed’ mug or calendar?

But what do you get the gardener in your life who already has a dozen or so mugs and calendars, bookcases overflowing with garden design, plant identification books and Canadian Gardening magazines, a shed full of shovels, trowels, pruners and every imaginable weeding tool that has ever been created.

So to my husband and anyone else who is looking for something a little different, I have attached my Christmas list:

Gardening Gloves

I know, I know I have at least 10 different pairs in the shed, but I must lose at least half of those pairs in a single season in my own backyard. Not to mention the other pairs I lose whilst gardening for someone else, or just simply driving, I’m not sure if they jump out of the car by themselves or simply get lost between the seats.

Gift Certificates

I’m pretty easy and flexible on these. Gift certificates for seed companies are always welcome, as is a gift certificate from Lee Valley, there has to be some tool I don’t already have. You can also purchase gift certificates from the many nurseries or garden decor/accessory shops in and around Peterborough, like those on the Peterborough and Area Garden Route. A gardener will always have room for one more plant, insect house or garden gnome.

Advance Passes to a Garden Show

Canada Blooms in Toronto in 2019 is being held on March 8-17; advance tickets can be ordered here. And locally the Peterborough Garden Show is on April 26-28; advance tickets can be purchased at numerous physical locations plus online.

GardenShow

Folding Garden Stool with Tools

We are all getting older and in my case also more forgetful. As well as losing gardening gloves, I also frequently lose my tools. My husband even tried painting the handles of my tools bright red so I would be able to find them easily, that did not work. Every summer I must find at least 1 pair of pruners and a hori hori knife (I currently have 3) from the previous year or two. So to save both my aching knees and not lose any more tools I am adding this stool to my list, which actually stores the tools under the stool.

Seed Bombs

No other reason than I love the look of these. If you look at some of the websites out there you can find them in many different colors containing different types of plant seeds, for example seeds specifically for pollinators. They are also small enough to fit in a stocking, and if you like to make your own gifts this could be something you could do yourself.

seed-bombs-2314498_1920

A Gardening Book

And finally, of course, a gardening book, but not just any gardening book. This book was listed in the Toronto Star as one if the ‘100 notable books of 2018’.
It is called ‘The Overstory’ by Richard Powers. I haven’t read this, hence it’s on my list, but I am intrigued by the description given in The Star: ‘The science of botany and the art of storytelling merge to ingenious effect in Power’s magisterial new novel – in which people are merely the underbrush and the real protagonists are the trees that the human characters encounter’.

I wish you all a very Merry Christmas and hope you all receive what you wish for under your tree.

Butterfly Gardening – Monarch Waystation #204

Leave a comment

by Mary Jane Parker, Master Gardener

Since 2008, my garden has been a monarch waystation.  In the beginning, when we purchased the property, we had to have a new septic system put in.  Because we are in a floodplain and the ground was saturated with water, we had to go up with the weeping tiles.  This meant that we had a berm at the front of the property and that was the beginning of my butterfly garden.

cottagejune23 038 (2)

Since then I have experimented with all kinds of native plants and wildflowers . The scope and layout of the property was such that formal gardens would have been impossible. Not all plants that I have tried have been successful but some have been my perennial favourites.

Monarda has self-sown over the years as has Phlox paniculata of which I probably have every colour available. Many plants have a personal history. Helianthus maximiliani came from Cathy Forget’s garden in Indian River and Glade Mallow (Napaea dioica) came from Mike and Sue Dolbey’s garden in Young’s Point. Many plants have come from gardens visited on horticultural trips near and far. I always leave room for native milkweed to grow. I have tried cultivated varieties of milkweed and unfortunately, they are not hardy here. The creek at the back of the property has an abundance of Joe Pye Weed (Eupatorium maculatum) growing naturally and I can’t think of anything prettier than when they are in bloom with the different shades of pink dancing in the breeze. I have always left room for Queen Anne’s Lace (Daucus carota) which not only attracts monarchs but a variety of interesting bugs. In the spring the Korean Lilac (Syringa meyeri) blooms are always a butterfly magnet.

Being a waystation has been fun. There are over 20,000 registered waystations around the world, most in North America, and although there are guidelines to follow, it does not appear that there are any hard and fast rules. The whole point is simply to provide habitat for monarchs and in doing so, you have a place that also attracts other butterflies, birds, and pollinators. Visit www.monarchwatch.org for more info.

Shady Gardens

1 Comment

by Sharleen Pratt, Master Gardener in Training

Now that the colder weather has arrived and the days are shorter, it’s time to dream about next year and possibly plan a new garden. Do you despair at the challenges surrounding a shade garden? We can enjoy the cooling effects of the shade and experience a garden that regales all of the senses. When choosing plants, consider interesting foliage and texture rather than solely depending on flower colour.

If you are planting under mature trees, especially non-native maples you must always remember that those vigorous, feeder roots quickly out-compete new transplants for water and nutrients. Every fall add several layers of shredded leaves as well as compost for additional nutrients. Remember to water often the first year.

There are many wonderful bulbs that would give you that burst of colour in the early spring before the trees get their leaves. The sun coming through the branches in early spring is perfect for encouraging Daffodil (Narcissus hybrids), Grape Hyacinth (Muscari botryoides) and Siberian Squill (Scilla Siberica) to flower before the tree canopy is in full leaf.

Hosta (Plantain Lily) are a must have in a shade garden and provides variations in leaf size, shape and colour. This perennial has hundreds of species and thousands of cultivars and they are tough, reliable plants. Along with the Hosta, you might consider Bleeding Heart (Lamprocapnos spectabilis). Their flowers hang down like dangling hearts and are a real source of delight. The dryer soil under a canopy of trees would quicken their disappearance shortly after flowering and would work well under the emerging large leaves of the Hostas. Another old-fashioned perennial is the Heartleaf Bergenia (Bergenia cordifolia) that has large waxy, heart shaped leaves. It also has some fall interest when the leaves take on a reddish winter hue.IMG_4094

Lungwort (Pulmonaria) are also shade tolerant and their delicately patterned foliage draws the eye throughout the summer. There are several species, some of which are variegated which can add texture and colour to the shade garden. Another perennial to consider is the Brunnera ‘Jack Frost’. This plant was named as the Plant of the Year for 2012. It bears panicles of light blue flowers held above silver leaves with green veins and edges. Once established, they can be fairly drought tolerant. An overlooked plant is the Foamflower (Tiarella cordifolia). It is a native groundcover and is happy in both full to light shade. It bears tall racemes of delicate white or pale pink flowers for six weeks in early summer. They grow best in moist, humus-rich woodland soil.

To give the shady garden some texture and shape, look at some of the broadleaf evergreen shrubs. The Oregon Grape Holly (Mahonia aquifolium) prefers moist, well-drained, acid soil. It produces very fragrant yellow racemes in mid-spring, followed by globose, dark blue fruit. Another broadleaf evergreen for shade is the Rainbow Leucothoe (Leucothoe fontanesiana ‘Rainbow’) a member of the Heath family with white urn-shaped flowers.

Take a close look at your growing conditions and plant accordingly. Put a bench under a tree and once established, the shade garden will be a wonderful oasis to roam and sit with a cup of tea and take in all the many senses surrounding you.

A good article that lists many perennials and groundcovers for a shade garden can be found at Landscape Ontario.

Spring Bulbs – Beyond Daffodils and Tulips

Leave a comment

by Suzanne Seryck, Master Gardener

October and November is a great time to plant spring bulbs – these are the bulbs that will extend the colour in your garden,  often blooming when there is still snow on the ground. These bulbs – the most well-known being daffodils and tulips – bloom from March or April until late spring. They are incredibly low maintenance, you plant them once and then forget about them, with the exception of daffodils which often need dividing every 5 years or so. However the reward outweighs the hardship of dividing them, a clump of 5 can easily multiply to 40 or 50.

Daffodils and tulips are, by far, the most recognized spring bulbs, coming in many different colours, sizes and bloom times. However if you look beyond, you start to notice the many other different spring bulbs available.

daffodils_EM

I live in Lindsay and like many cities, if you drive around in the spring, you will notice the many blue lawns. These are actually either glory of the snow (Chionodoxa spp.), or siberian squill (Scilla), tiny blue bulbs that naturalize in both your lawn and your flower beds. The difference between the two depends on the direction that the flower head faces, but either are perfect in the lawn. As well as blue they also come in lavender, pink or white.

Squill_EM

Snowdrops (Galanthus), which are among the earliest blooming spring bulbs will also naturalize in your lawn or flower beds, however in my garden, they are slower to multiply. They can be either single or double with a small white or snow colored flower.
I plant a lot of grape hyacinth or muscari in my garden, however I find them too large for my lawn and instead plant them in the perennial beds. They are also great under shrubs, trees or hedges. They come in blue, violet, pink and white and multiply easily, quickly spreading to form large clumps. Blue muscari works very well when paired with daffodils and can be planted in the same hole. Bulbs are typically planted at a depth determined by the size of the bulbs, allowing you to layer the muscari on top of the daffodils.

Crocuses whilst beautiful in their many different colours seem to be especially appetizing to squirrels. I planted orange crocuses two years ago and out of the twenty crocuses I planted, I may have seen one actually bloom, I was left with either holes where the bulbs used to be, or they would be nipped off when they were about 1 inch tall. I still plant them, but I make sure to plant a daffodil in the same hole, squirrels do not like the smell of daffodils and tend to stay away.

Other spring bulbs I have planted in my gardens include anemone, oxalis adenophylla, which is a very pretty pink colour, hyacinths, winter aconites, a very cheery shade of buttercup yellow, iris hollandica and of course English bluebells. I have to admit I do have a lot of daffodils and tulips in my garden from my early gardening days, but I am now starting to look beyond and plant the many different spring bulbs now available.hyacinths_EMHint: If you’re looking for ideas for something different check out this GardenMaking magazine article with ideas for 25 unique bulbs for your garden.

Planting to Encourage Proper Root Growth and Branching

1 Comment

By Sue Flinders-Adams, Master Gardener

Here are a few tips to ensure that the new shrub or tree you just brought home will thrive and grow to its full potential.

1. Before planting, soak the plant in the pot, in a pail of water for a few hours or even overnight to hydrate the roots.

2. Carefully remove plant from the pot. If it doesn’t come out easily gently press on the sides so that the roots will come away from the pot, and tap on the bottom.

3. There are usually roots circling the pot – gently coax these roots away from the root ball to encourage outward growth. If roots are left in the ‘circling’ position, they will continue to grow in this direction, circling the plant and even girdling the trunk of the tree in 10 or 15 years.flinders pic 1

4. The picture shows the roots that have been spread out in the very large hole. Partially cover the roots to hold them in place and water thoroughly with transplant fertilizer, according to the directions. Fill in the hole with the surrounding soil. Top dress with an inch or two of composted manure, and then 3 inches of mulch. Prune off any dead branches.flinders pic 2

5. Branches are often cramped and a little twisted from shipping. Gently pull them away to a better positon and secure with plant supports (pictured). In a couple of weeks you can take the supports away and the branches will continue to grow in that direction.

6. flinders pic 3Three weeks later, the Black Lace Elder is looking very happy. It is October which explains the lack of new growth.

The Plant Lover’s Guide to Salvias (Book Review)

Leave a comment

By:  Mary Jane Parker, Master Gardener

If you care deeply about natural gardening and attracting bees, insects and hummingbirds to your garden, then salvias should be one of your go-to plants. They have wonderful flowers and fragrant leaves and for me, they bloom almost all summer.

In this very readable book, The Plant Lover’s Guide to Salvias, John Whittlesey outlines designing with salvia plants in different climate zones. We learn that salvias are generally hot climate plants and many have low water requirements but some of the perennial ones can be treated as annuals in our climate. Some are rated for zones close to ours and will survive here as perennials. I have had Salvia glutinosa growing here for many years and the book rates that one only a US zone 6a. Culinary sage (Salvia officinalis) has overwintered for me also for a number of years.

hummingbird 1851489_640

The author next goes through and discusses 150 species and exceptional hybrids, their country of origin and specific cultural practices for each and any notable characteristics such as a strong hummingbird attractor.

Finally, he discusses general cultural techniques and then provides a listing of sources for plants and seed. After having read the book and descriptions of different salvia species, I have ended up with a two-page list of interesting species I wish to try.

The Peterborough Horticultural Society has this book available in their lending library or you can purchase from Timber Press.

New Garden Planning; a Look Ahead

Leave a comment

By Cheryl Harrison, Master Gardener

Fall is a great time to get a head start on the new garden that you have been dreaming about for next year.

Deciding the new garden’s location depends on the purpose of the garden.  Will it be a quiet area for relaxing?  Look at the view from outside and also through the windows from inside your home when assessing potential locations.

Consider the growing conditions.  Is the potential location windy, sunny, shady or combination sun/shade?  It may be important to know the location of utility lines and pipes depending on how radical the planned change to the landscape.  Do you have access to water?  New plants usually need supplementary water for their first year.  Also check the area for flooding and provide drainage when necessary.IMG_1164

Think about garden structures……perhaps an arbor, fence or pergola or maybe a bird bath or bench?  For larger structures, you may need a construction permit.  A landscape professional can be a great person to consult at any stage of planning.

Soil condition is vey important to the growth of plants.  Newly built homes often have very little topsoil layered over nutrient poor subsoil.  It may be necessary to dig out some of the subsoil and replace it with good topsoil.  This “digging” step is when to be aware of the location of your utilities.

Create a new garden by edging the chosen area with a sharp shovel or edging tool then placing the material (usually a combination of grass and soil) into the centre of the new garden location.  Smother unwanted growth by covering the area with 4-5 layers of newspaper, or cardboard, and water it down.  Then layer topsoil about 15 cm (6 inches) on top and add additional organic material like composted manure.  Finish the new garden bed with a 7-10 cm (3-4 inch) layer of mulch.  The newspaper/cardboard layer, and the mulch will eventually decompose to become part of the garden’s soil.

Your new garden bed is ready for planting.  Choose plant material by looking at plant catalogues and on web sites.  What a great way to spend a fall or winter afternoon!
