Bringing in Your Tropicals for Their Annual Winter Spa Treatment

By Mary-Jane Pilgrim, Master Gardener

Note: The article was also published recently in the Peterborough Horticultural Society September 2021 newsletter. Apologies to PHS members who have already enjoyed it!

If your houseplants are on “vacation” on the back deck this summer, then at around this time you should think about getting them ready to move back inside for the winter.

Bring your houseplants indoors before night time temperatures dip below 7 or 8 degrees (C).  Most tropicals will suffer damage at temperatures below 5 degrees, a few even below 10 degrees.

Sudden changes in temperature, light, and humidity can be traumatic to plants, resulting in yellowed leaves, dieback, wilting, and even death. To prevent shock when you bring houseplants back indoors, expose plants gradually to reduced lighting.

Before moving day, inspect plants for insects and diseases, and treat as appropriate before bringing plants back inside.  Spray them a couple of times over a 2 week period with a mild soap and water mix so that you don’t bring bugs from outdoors in with your plants.  Alternatively, soaking the pot in a tub of lukewarm soapy water for about 15 minutes will force insects out of the soil. Allow the plant and pot to dry completely afterwards.  If snails, earthworms, or other insects burrowed in the soil, you might want to repot the plants, placing a piece of wire screening over the drainage hole to keep them out next year.

Personal anecdote:  A couple of years ago, I brought a large cactus planter inside without inspections or the soaking method. The next day, we found a curious “deposit” left behind by some unknown critter on our kitchen floor and we kinda freaked out.  We set live traps in the house and were on high alert for a chipmunk or squirrel or even something huge with big teeth that could drag us out of bed by the big toe.  It was a little bit traumatic.  A day or so later, my son found a large toad in the living room and we connected the dots.  Turns out that toads leave very large deposits for their body size (Google it!) and closer inspection of the cactus planter showed an open hibernation hole. Whew!

Moral of the story? Check your plant pots for toads too!

Stripey Things in the Garden

By Mary-Jane Pilgrim, Master Gardener

A couple of weeks ago, Laura Gardner posted an article in this blog about insects in our gardens in general. I’d like to follow up on that post with one specifically addressing the variety of stripey flying insects in our gardens.

Bees, wasps and hornets are often lumped into one stinging group but is important to understand the difference between bees, wasps and hornets in order to appreciate their significance in the garden.

Bees are mostly hairy, have fat legs and short fat bodies. They eat pollen and nectar, and in the process of gathering these, they pollinate flowers. Bees die after they sting. There are over 400 discovered varieties of bees in Ontario.

Wasps and hornets have hairless bodies and tend to be long and sleek with a narrow between the abdomen and thorax. They are predators and for the most part they eat other insects. A hornet is a larger type of wasp with black and white rings instead of black and yellow. The most common type of wasp in Ontario is the yellow jacket, but there are three others in this region: Bald faced hornets, paper wasps and mud dauber wasps. Wasps and hornets do not die after they sting, and can sting multiple times.

For the most part, wasps are not important pollinators but they are hunters and their prey is other insects. They play an important role in protecting your plants. Wasps spend their summers seeking out aphids, flies, caterpillars and other bugs – many of them pests – to feed to their larvae. Hundreds or even thousands of larvae can be produced each year in a paper wasp hive, so they look after a lot of bugs!

How can we coexist with these scary, menacing fliers? Wasps sting when you threaten them. If you get stung it is probably your fault – it may not be intentional – but you are still to blame. If you swing at them or make sudden movements, they will feel threatened and there is a good chance you will be stung. The best way to avoid the pain is to treat bees and wasps with respect. Move calmly and deliberately, give them space to go about their business, and they will ignore you. If you do get stung, wash the area with soap and water and apply an ice-pack. You might want to take an anti-histamine tablet or use an anti-histamine lotion. If you have an extreme reaction, get to the ER fast. Otherwise, try a fresh-cut raw onion (it has enzymes that counteract the venom), anti-perspirants that contain aluminum zirconium, After-Bite, or a simple paste made from baking soda and water to ease your suffering.

Most people don’t want to have wasps living alongside them, but if you can possibly leave the nest alone, it is advisable to do so. After all, wasps are so common that even if you can’t see a nest, it’s probable there’s one nearby. The wasp colony will die when the cold weather hits. If the nest is left in place it is unlikely that wasps will build there again the following year, so you can dispose of any visible wasp nests in winter or early spring. The only wasps to over-winter are the fertilized queens which start new colonies in the spring.

The best way to deal with wasps is to minimize their numbers by deterring them from the area. Do not keep any food (including your pet’s) lying around. Keep drinks covered when outdoors and always ensure that garbage cans are tightly sealed. Also, keep any fallen fruits from nearby trees, shrubs and gardens picked up as their sweet juices attract the wasps.

Fake wasp nests are available to the homeowner to hang in trees near the house. Since the wasps are territorial, they will probably set up housekeeping somewhere else.

Last year, we had wasps nesting in two places under our vinyl siding. Since they were near our back door, we tried some of the sprays available but found that they weren’t effective. One day, I bravely (and quickly) put duct-tape over the nest entrances, and the problem was solved instantly. If only I’d tried that before heading to the hardware store!

If you can find a way to coexist with the majority of these insects, your gardens will thank you.

Lending Insects a Helping Hand in our Gardens

By Laura Gardner, Master Gardener in Training

When some of us think of insects, it is common for them to be thought of in a negative light. Some of our earliest childhood memories include being stung, bitten, or just plain scared by the sight of them. I can remember running screaming from an outhouse at a provincial park when I was about five years old. What was so scary? It was the sight of a Yellow Garden Spider (Argiope aurantia) hanging in its web in the stall. Fortunately, the experience didn’t make me fear or dislike spiders and as a gardener I know how beneficial they are to have around. While some insects certainly do deserve our scorn— invasive species such as the LDD moth (Lymantria dispar dispar); Emerald Ash Borer (Agrilus planipennis); Japanese Beetle (Popillia japonica), etc.—by and large, the majority of insects are harmless and beneficial. Not long ago, I saw a couple—perhaps grandparents, out for a walk with their grandson. One of them was urging the young boy to stomp on an ant on the pavement, calling out “Get it! Get it!” It was disheartening to see. It is experiences like this that call for a shift in our thinking about insects.

Bumblebee (Bombus sp.) on False Sunflower (Heliopsis helianthoides)

I recently got a sneak preview of a book by British entomologist Dave Goulson called Silent Earth: Averting the Insect Apocalypse (Harper Collins). It is to be published this Fall (September 2021). The copy I reviewed was an e-book proof and so page numbers referred to here may change in the final published copy. Goulson’s work is primarily focused on bumblebees and as the founder of the Bumblebee Conservation Trust in the UK, he is dedicated to reversing the decline of them. He is also known for his work that was instrumental in influencing the European Union’s decision to ban neonicotinoids in 2013. Goulson wrote this book in an effort to bring more public attention to the recent and rapid decline of global insect populations—which are critical for our planet’s survival. He also explores the chief causes of insect declines such as habitat fragmentation, industrial farming practices, pesticides, climate change, and non-native insect diseases (p. 71) and provides suggestions for readers that can help support insects—especially gardeners.

Bumblebee (Bombus sp.) on Sweet Joe Pye Weed (Eutrochium purpureum)

Here are a few highlights from the book:

Goulson refers to a phenomenon called “Shifting Baseline Syndrome” where humans tend to only see their current world as “normal” and are unable to detect changes over time. Humans also tend to have something called “personal amnesia” in which they downplay the extent of change (p. 64-65). With these points in mind, it is no wonder that most people would not know that insect populations have recently declined by as much as 75% (p. 50) and that there have been parallel declines in populations of insectivorous birds (p. 58). One bird that I remember as a child that I haven’t seen since is the Eastern Meadowlark (Sturnella magna). This species is one of those that depends on insects in its diet.

One concern that the author has is the level of human awareness of the existence of the natural world. It is important to learn the names of plants and animals—otherwise they cease to exist. If they don’t exist, their importance can’t be recognized. Astonishingly, in 2007, some of the words eliminated from the Oxford Junior Dictionary included words such as acorn, fern, moss, clover, kingfisher, otter, among others (p. 225).

87% of all plant species require pollination in order to flower, produce fruit/seeds, and ensure perpetuation of the species. This includes 75% of all agricultural crops (p. 26). Most of this is performed by insects and a large part is performed by those other than bees—flies, ants, beetles, wasps, moths and butterflies. A world without insects means that we would need to subsist mainly on cereal crops as these can be wind-pollinated. I can’t imagine going without fruits such as strawberries, apples, cherries, raspberries, and even my morning coffee (p. 26).

Insects are not only important pollinators, but they assist in the development of healthy soils. Not only do they help to aerate soil, they are valuable decomposers of organic matter—participating in a process along with bacteria that help make nutrients more available to plants (p. 29, 31).  As biological control agents, predatory insects such as Lady Bugs (Coccinellidae spp.), Lacewings (Chrysopidae spp.), Ground Beetles (Carabidae spp.), Wasps (Vespidae spp.), etc., can help us reduce the need for pesticides.

Blue Mud Dauber (Chalybion californicum) on Swamp Milkweed (Syriaca incarnata)

What can we do to help?

Despite the current state, Goulson is optimistic that insect declines can be stabilized or reversed because they are generally good at reproducing—we just need to support them better (p. 216). Here are some ideas:

  1. Learn how to identify the difference between harmful and beneficial insects. The majority (95%) are the latter.
  2. Reduce or avoid the use of pesticides and give beneficial predatory insects a chance to take care of the problem first (p. 277). Even so-called organic treatments such as diatomaceous earth, BTK, horticultural oils, etc. need thoughtful consideration before use as they can harm harmful as well as beneficial insects.
  3. Learn how to differentiate between irreversible and cosmetic damage in your plants. Accept that plants are meant to be food sources for insects and some imperfections and damage is ok. Give up growing ornamental plants that are persistently defoliated by certain insects (e.g. Asiatic Lilies).
  4. Incorporate a wide range of native plants that flower throughout the season in your garden to attract beneficial insects. One of the best late flowering perennials is New England Aster (Symphyotrychum novae-angliae). It provides a valued food source for migrating Monarch butterflies. Some of the best food sources for insects are early flowering trees such as Serviceberry (Amelanchier spp.), Maple (Acer spp.), and Crabapple (Malus spp.).
  5. When using mulch in flower beds, leave some soil exposed so that ground nesting bees can have easy access. Some solitary wasps such as Mud Daubers (Sphecidae spp.) also need easy access to bare soil in order to glean material to build their nests.
  6. Reduce lawn and use the space for more plants. Reduce mowing of the lawn that exists. Allow a corner of your garden to “grow wild” and “get messy.”  (p. 277).
  7. Choose native plants over “nativars.” A nativar is a cultivated variation of a native plant. Some are supportive of pollinators but many are sterile or lack pollen and therefore are unable to provide food. The ones that are most likely to be the least supportive will have features such as double blooms, different leaf colours, etc. Reduce planting of ornamental annuals like Petunias, Begonias, Pansies, etc. because of their tendency to have no pollen or nectar (p. 233). That being said, some of these plants can still be enjoyed.
  8. Choose a range of plants that support the broadest number of insect species. While Milkweeds (Asclepias spp.) are in the limelight as being supportive of Monarch Butterflies (Danaus plexippus), compared to some other plants, they only support 12 Butterfly and Moth species (Tallamy, Bringing Nature Home). Goldenrods (Solidago spp) support 115 different species. Some, like Canada Goldenrod (Solidago canadensis) can be aggressive in small gardens but there are more restrained types such as Blue-Stemmed Goldenrod (Solidago caesia), and Zigzag Goldenrod (Solidago flexicaulis).
  9. Avoid aggressive fall and spring clean-up of leaves and hollow, dead stems. Doug Tallamy describes the practice of waiting 7-10 consecutive days of 10 degree C. temperatures for insects to emerge as myth as many insects emerge at different periods throughout the season. For example, Io (Automeris io) and Luna Moth (Actius luna) emerge around mid May (Tallamy, Leaf Litter: Love it and Leave it).
  10. Recognize that commercially produced “Bee Hotels” can become populated by non-native bees such as European Orchard Bee (Osmia cornuta), Horned-Face Bee (Osmia cornifrons), and Blue Mason Bee (Osmia coerulescens) as well as native bees (p. 135). If used, periodically clean them so as to reduce mites and fungi that can be harmful to the bees.
  11. Reconsider taking up beekeeping as a hobby. The European Honey Bee (Apis mellifera) threatens native bees because they take the lion’s share of available plant pollen (p. 139). It is also not a good strategy to rely on one species for pollination in case something happens to that species (p. 33).
  12. Raise awareness and share your knowledge with family and friends. You can convince others that insects need our help if they realize they themselves will be personally impacted by their decline (p. 216).

Monarch Butterfly Caterpillar (Danaus plexippus) on Swamp Milkweed (Syriaca incarnata)

Hosting butterflies

By Lois Scott, Master Gardener

Life has been busy in my garden lately, and I don’t necessarily mean me! My husband Ray and I have been enjoying the array of pollinators that are busy in the garden. What has us particularly excited is seeing species of butterflies that we have not noticed in the garden before. For example, Ray identified a Large Wood Nymph butterfly (Cercyonis pegala) that I noticed feeding on heliotrope. Although it spent a lot of time feeding on the heliotrope this is not a host plant for this particular butterfly. According to The Audubon Society Field Guide to North American Butterflies host plants for the Large Wood Nymph are native grasses such as Little Bluestem (Schizachyrium scoparium).

Large Wood Nymph butterfly

So, what exactly is a host plant and why is it important? Host plants are plants that an organism, (larva) lives on and lives off of. A well-known example is the Monarch butterfly. It will feed on a number of nectar plants including milkweed but Monarch larvae only feed on milkweed (Asclepias) species. Milkweeds are the Monarch’s only host plant. Important pollinators like butterflies and moths need host plants on which to lay their eggs and enable the subsequent larvae to have a food source. The photo below shows Little Bluestem (Schizachyrium scoparium) in the foreground is a host plant while the Mexican Sunflower (Tithonia rotundifolia) behind it is a nectar plant.

Little Bluestem grass and Mexican Sunflower provide host and nectar sources (respectively).

According to the Ottawa Field-Naturalists’ Club (OFNC) butterflies need plants that are good sources of nectar, sun, shelter from the wind, and host plants on which to lay their eggs.  Yes, larvae eat the leaves on the host plant but typically do not cause serious damage.  Along with providing a list of plants for nectar sources this site gives a list of host plants for larvae for specific butterflies.  Many of the host plants are trees including birches, willows, dogwoods, oaks, hops, cherries and hackberries to name just a few.  Other host plants include native wildflowers and grasses.

The OFNC site provides more details on providing the most desirable conditions for butterflies and makes the point that to restore butterfly populations we need to recreate suitable habitats for them. This is another list of valuable host plants.

If you are interested in attracting more butterflies consider adding some of these valuable host plants to your garden. Many of these plants can be sourced at Peterborough’s Ecology Park where you can also get expert advice on suitable plants for your garden conditions.

Don’t Spring into Spring Clean-Up just Yet

By Anica James, Master Gardener in Training

Spring is finally here, a time for new beginnings. The days are getting longer, birds are singing their hearts out and the snow has melted for the most part, but it’s still too soon to do any kind of clean up in your yard. It may be tempting to get out the rake or leaf blower just because it’s sunny and leaf bags are on sale at your local box store, but we need to hold off just yet for the sake of helping other creatures and pollinator species who are still asleep.

Although we are all anxiously waking up from our own personal winter hibernation–whether it be mental or physical–many creatures around us are still sound asleep in the leaf litter or below the mulch and we should not disturb them just yet. When you clean up your yard too soon, all for the sake of aesthetics or curb appeal, you are essentially removing all of the beneficial insects in your vicinity, like those responsible for making your flowers bloom or for your fruit and vegetable plants to produce food.

Some beneficial pollinators overwinter in the hollow stalks of perennials and under rocks. Examples of insects local to us that are still in diapause state are butterflies (like Mourning Cloaks or Question Marks), lacewings, ladybugs, mason bees and parasitic wasps, which all spend the winter either as pupae or adults hidden away in your yard. Even Luna moths and black swallowtails spend the winter months in cocoons or pupa that look just like a crumpled brown leaf, so be on the lookout for those.

It is best to wait until the temperature is consistently 10 degrees Celsius before you start raking leaves, turning soil, or using a leaf blower. Personally, I like to play it safe with the 10 For 10 rule: 10 degrees for 10 days. This allows nature to take its course and it allows me to have enough time to observe my property and familiarize myself with the various kinds of flora and fauna that emerge post-winter.

If you do decide you feel so inclined to “tidy up” this early, do it with purpose and be mindful of the sleeping and living creatures that are still hidden away. Take your time, look for any signs of beneficial insect stages and either take note and leave it for a later date, or carefully cut and set it aside in a natural area so solitary bees and others insects can still use the refuse for food or shelter. Refrain from adding more mulch because it can trap certain kinds of beneficial bees, beetles and flies that burrow in the ground (almost 70% of Canada’s bee species nest underground). For more information on how to properly “clean up” your yard read Nesting and Overwintering Habitat for Pollinators and Other Beneficial Insects PDF by the Xerces Society.

But again, the best thing to do is wait and to try to remove as little from your property as possible.

So in the meantime, what can you be doing instead of gardening?

  • Get outside, go for walks, enjoy the little things; notice the bulbs emerging naturally and gracefully from the cool earth, poking their way through the leaf litter- now is the time to enjoy the scilla, crocus, pushkinia, galanthus and helleborus
  • Continue to sow vegetable and annual seeds indoors and plan your garden; what are your goals for this year, however big or small?
  • Early spring is the best time of year to be on the lookout for invasive pests and plant species and begin to develop an Integrated Pest Management plan; gypsy moths, garlic mustard, european buckthorn, and goutweed are commonly found throughout the Peterborough area
  • Focus on spring cleaning your tools, your patio furniture, tidying your deck, potting bench or shed; put more focus into the inanimate things
  • Celebrate the beginning of spring by honouring the maple tree, it’s delicious sap and syrup, and the work that goes into providing us all with natural liquid sugar; maybe consider ordering a maple for your own yard
  • Repot indoor plants if needed
  • Read up on and think about ways you can increase pollinator habitat on your property or within your community, no matter the scale

There is so much that you can do while resisting the urge to rake or blow. Relax, enjoy the much needed sunshine that the vernal equinox has brought us after the long winter and try to go at the same pace nature is. Patience will pay off in the long run once you remember that gardening isn’t just about plants.

Great resources for more information about pollinators that spend the winters in our gardens and why we should hold off until mid-April to start yard work:

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!

Beware the caterpillar

By Suzanne Seryck, Master Gardener

Fall is my favourite time of the year to bicycle; not too hot and the scenery on trails in the Kawartha Lakes is beautiful. Asters and golden rod are in full bloom; the sumacs and Virginia creeper are just turning red, whilst the maple trees are slowly turning various shades of orange, yellow, red and brown. My only problem is trying to miss all the caterpillars, grasshoppers, and chipmunks, not to mention the odd rabbit or snake that crosses my path. I can’t count the number of times I have almost ended up in a ditch.  Everything mostly jumps or slithers out of my way, though, with the exception of the woolly bear caterpillars.

Photo taken by author whilst out riding

You would think that these caterpillars would be fairly easy to spot, but at this time of year, and probably at my age too, I tend to have problems distinguishing them from leaves, especially from a distance. The caterpillars normally emerge around this time of year, slowly inching their way across the paths.

Picture of woolly bear caterpillar (taken by author)

The woolly bear caterpillar will emerge from its larva in the fall, and overwinter in its caterpillar form. It does this by finding a safe spot to hibernate under leaves or bark or inside rocks or logs and then freezing solid. It is able to survive being frozen by producing a cryoprotectant, which is a substance that protects its tissue from freezing. The search for a safe hibernation spot is why you see so many of these caterpillars crossing roads and paths.

In the spring the caterpillar will wake up hungry, eat for a few days and then spin a cocoon emerging after a couple of weeks into an Isabella Gypsy Moth.

There are many old wives tales that specify that the size of the brown bands in the middle of the caterpillar or the number of brown bands will determine how hard a winter we will have. This was investigated in 1948 by Dr. C. H Curran who was the Curator of insects at the American Museum of Natural History in New York. To read more about this, please refer to the following article: https://www.almanac.com/content/woolly-bear-caterpillars-and-weather-prediction

Whilst I eagerly await the time when all the caterpillars have finished crossing roads and paths and begun their hibernation, I will continue my daily bike rides looking down at the paths whilst attempting to ensure that I do not cycle into any more ditches.

Adding Diversity to Garden Design

By Suzanne Seryck, Master Gardener

In June this year, I was sitting with my son on the deck looking at the backyard. He asked me why I had so much grass in the garden. Now, he is definitely not a gardener, so I was a little confused until I realized he was referring to all of the daylily leaves. I felt it my duty to point out the stunning delphiniums, peonies, irises, and lupins which were all in bloom. I also tried to explain that in another month or so the garden will be a riot of colour when all the daylilies and coneflowers started flowering. Daylilies have always been my favourite plants; they are hardy, drought tolerant, low maintenance and beautiful in bloom. See our blog post from July 22 describing how daylilies are the perfect perennial. I probably have at least fifty different varieties, all of which I bought over from my last garden four years ago. But as I sat there looking at the garden I did wonder if maybe I should add more diversity.

thumbnail_garden in latespring
Author’s garden in late spring

Shortly after, I was watching my new favourite garden show on Netflix, ‘Big Dreams, Small Spaces’ with Monty Don. If you have not heard of him, Monty Don is something close to a hero to most British gardeners. In this episode, he was relaying a gardening principle to the couple that were designing their new backyard.  He mentioned that for simplicity and cohesiveness “no garden needs more than seven different plants”.  I was trying to remember where the back button was on the remote as I wasn’t sure I’d heard correctly, but he did partially redeem himself when he clarified that statement by saying that you do not have to take this too literally, but that a good garden can be made with just seven different plants. My current garden design is more of an English cottage garden, informal with little space between plants and if I was going to add more diversity this summer, I would definitely have more than seven different plants.

I spent this summer with pen and paper in hand walking around the garden, asking myself if I really needed 20 different variations of pink daylily, some of which even I struggled to tell apart or did I need the same daylily variety in four different places in the garden. I also noticed the daylily blooms had very few insects compared to the spectacular activity around the native plants. I made copious notes in my notebook and labelled many plants I wanted to move or give away. Because of a rising concern for environmentalism and climate change, I also wanted this to be reflected more in my garden. To do this I decided I needed to do the following:

  • Plant more native plants. I have collected seed from most of my native plants including swamp milkweed, culver’s root and liatris and will use these to fill in over the next few years.
  • Add more edibles to the perennial garden. I tend to edge with swiss chard, beets or cardoon. I don’t actually eat the cardoon but I love the foliage on the plant.
  • Choose more plants that have multiple functions, i.e. yarrow which attracts insects, is drought tolerant, is a nutrient accumulator bringing nutrients from deep in the soil and storing them in the leaves, has attractive flowers in many colors, and can be used as a manure tea.

Author’s garden in summer

I’m excited for next year to see the changes I’ve made. I’m hoping that I have still kept the basic structure of the garden design with the emphasis on the summer color whilst adding more variety, especially pollinator and native plants. I learned this summer that a garden design does not have to be static; it can evolve as your values and beliefs evolve.

The design of your garden can be very personal, ever changing, reflecting who you are. For me it is somewhere where I feel at peace with the world–there is nothing I like more than taking a cup of tea out to the garden in the morning and just sitting and looking around.

Attracting Birds 1

By Judy Bernard, Master Gardener

The end of February, I saw a Cardinal at the bird feeder the first time this winter. They are such a beautiful bird, and one doesn’t see them that frequently. If it weren’t for our bird feeders, I don’t think I’d ever see one.

asparrow-3537687_960_720 (3)

Birds are a very important part of our garden environment. They eat seeds, berries and most importantly for the Gardener, they eat insects. One of the most common birds to visit my feeders are chickadees. They enjoy both sunflower seeds and peanuts. In the summer they eat more insects including aphids, whitefly, scale,  caterpillars, ants and earwigs. Other insect eating birds that visit my feeders are cardinals, nuthatches and grosbeaks. Although they eat very few insects, if any, finches are are welcome visitors to our feeders just for the pleasure they give us. I do all that I can to encourage the  visits of all birds.

Although it may not seem like it at times,  bird feeders aren’t the primary food source for birds, foraging is. Birds rely more on the nutrition provided by seeds in bird feeders in the winter  as  the supply in their environment dwindles and they need to go further afield to find other sources of food. To keep the birds coming to my garden, I keep my bird feeders out all year. It is such a pleasure to have their visits.

In subsequent posts, I will talk more about bird feeders, bird food, and providing an environment to attract birds to your garden.
