Recently, I have grown to love maple syrup for more than just its delicious taste. The harvesting and boiling of the sap brings me outside in the fresh air during a time of year when I need it most. But I’ve wondered what makes this harvest season so short, so specific and so unique.
First, the Sap

During the growing season, sugars needed for tree growth are created via photosynthesis and stored in the tree as starches in the sapwood. When the weather cools, starches are converted back to sugars and passed into water flowing through the xylem of the tree, creating sap.
How Water Moves Through the Tree
Typically, water moves up the tree from the roots through cell channels called xylem. Since the xylem is made up of dead elongated cells, these cells don’t contribute to the movement of the water, they rely on pressure gradients. In maples, a unique pressure is present in the springtime, but only when it freezes at night and thaws during daytime.

Maple Magic in Spring Time
Just outside of the xylem vessels are dead wood fibre cells with air inside. When the temperature drops in the evening, the smaller branches at the top of the tree freeze first, and sap frost collects in the air-filled wood fibre cells surrounding the sap-filled xylem. This creates suction, pulling sap up the tree. When the temperature rises in the morning, the frost melts and falls down the tree through the xylem by both gravity and pressure created by the warming air in the wood fibre cells. This is when you get to collect!
What about Fall?
But wait! We don’t just get freezing at night and above freezing daytimes in the spring. That happens in the fall too. Can you tap maple trees and make syrup in the fall too? The answer is yes, but researchers have found you won’t get as much as springtime, and the sap won’t be as sweet. Additionally, it will reduce the sweeter springtime sap yields as well. Worth it? Probably not.
The Pros Know What They’re Doing
Tapping only once a year also helps to reduce injury and therefore risks to the tree caused by severing its protective layers and exposing it to external factors. Hobbyists and large-scale producers alike want to foster a healthy tree that provides delicious syrup for years to come.
Tucked away in the cool corners of gardens, beneath leafy cover and damp soil, lives an unassuming champion of ecological balance: the American toad (Anaxyrus americanus). With their warty skin, endearing hops, and golden eyes, these amphibians may not boast the charisma of butterflies or hummingbirds, but their contributions to gardens are unparalleled. Often overlooked, the American toad quietly goes about its work, consuming pests, enriching the soil, and maintaining harmony in ecosystems. It’s time we shine a light on these remarkable creatures and embrace their presence in our outdoor spaces.
American Toad showcasing why warty skin is so great at camouflage
The American toad, native to eastern North America, thrives in a range of environments, from woodlands to suburban backyards (Elliott et al., 2009). Unlike frogs, toads are covered in warty, textured skin, an adaptation that provides effective camouflage against predators. This camouflage, combined with their nocturnal habits, allows them to move unnoticed as they perform their crucial ecological roles. Chief among these roles is pest control. Each evening, American toads emerge from their shelters to feast on insects, slugs, and other invertebrates. By consuming thousands of pests in a single season, they provide natural, chemical-free pest management, an essential service for gardeners and farmers alike (Mitchell & Lannoo, 2020).
In gardens, toads reduce populations of harmful insects like beetles, cutworms, and mosquitoes, preventing these pests from damaging plants or spreading disease. Unlike chemical pesticides, which often harm beneficial insects and pollute the environment, toads work in harmony with nature, maintaining ecological balance without collateral damage (Relyea, 2005). Furthermore, their waste contributes organic nutrients to the soil, promoting plant health and improving soil quality—a testament to the interconnectedness of life in the garden.

The life of an American toad is a remarkable journey of survival, reproduction, and adaptation. During the day, toads shelter under rocks, logs, or thick vegetation to escape predators and prevent dehydration. At night, they hunt using their long, sticky tongues to capture prey with incredible precision. In spring, their lives become even more captivating as males gather at ponds, streams, or garden water features to call for mates. Their trills, a hallmark of the breeding season, are a welcome sign of spring. After mating, females lay long strings of eggs, often numbering thousands, which hatch into algae-grazing tadpoles within days (Elliott et al., 2009). These tadpoles play a vital role in keeping aquatic ecosystems healthy by controlling algae growth.
Toads are also experts at enduring winter, surviving through a process called hibernation. As temperatures drop, toads burrow deep into the soil, often using loose dirt, leaf litter, or even garden waste as insulation. These layers protect them from freezing temperatures and provide shelter from predators (Mitchell & Lannoo, 2020). For this reason, leaving leaf piles and garden debris untouched during fall and winter is critical. These natural materials serve as vital hibernation sites, not just for toads but also for other beneficial creatures like pollinators and soil invertebrates. Clearing the garden too early in the spring can disrupt or destroy these overwintering habitats, inadvertently harming the wildlife that supports your garden’s health. Waiting until temperatures consistently rise ensures that these creatures can safely emerge and resume their roles in the ecosystem.
Despite their adaptations, American toads face numerous predators, including snakes, birds, and mammals. However, their warty skin serves as more than camouflage—it secretes a mild toxin that deters many would-be predators (Mitchell & Lannoo, 2020). Some toads even use dramatic behaviors, such as flipping onto their backs and feigning death, to discourage attacks.
Beyond their ecological contributions, American toads are fascinating creatures with unique traits. They can live over a decade in the wild, a testament to their resilience and adaptability (Elliott et al., 2009). They can also change their skin color slightly to blend with their surroundings, shifting between lighter and darker tones based on temperature and humidity. These subtle abilities add to the toad’s allure for those who take the time to observe them closely.
Creating a toad-friendly garden is simple and deeply rewarding. To attract toads, provide shelter using overturned flowerpots, rocks, or logs, and allow areas of dense vegetation or mulch for shade. A shallow water feature is a magnet for toads, especially during breeding season, but ensure the water source has sloped edges to allow easy entry and exit. Perhaps most critically, avoid using pesticides and herbicides, which can harm toads directly or contaminate their food sources (Rowe et al., 2001). Leaving leaf litter and reducing outdoor lighting can also make your garden more inviting to these nocturnal helpers.
A garden with toads is a garden alive with balance, biodiversity, and beauty. These humble amphibians are more than just pest controllers—they are symbols of a healthy ecosystem, reminding us of nature’s intricacy and resilience. By encouraging toads to share our outdoor spaces, we not only protect these vital creatures but also create gardens that are richer, more sustainable, and teeming with life.

Having just come back from places where tropicals are growing wildly and flowers are blooming, I wanted to discuss growing zones and the importance of knowing your zone for overwintering plant success of perennials, trees and shrubs.
Plant hardiness zones can be a confusing subject. In Canada, we generally use the USDA (United States Department of Agriculture) system because it is the one we often see on labels of the potted plants we purchase at greenhouses and big box stores.
The USDA system was designed in 1960, updated in 2012 and again in 2023. These hardiness zones are determined as “geographic areas that have an average annual minimum temperature of a certain degree.” No other factors are taken into consideration. There are 13 zones with zone 1 being the coldest and zone 13, the warmest.
Natural Resources Canada has their own system which uses factors that include the number of frost free days, amount of rainfall, snowfall, and wind as well as mean temperatures in the coldest and warmest month. There are 9 zones. Interestingly, Ontario has 7 of these zones.
To complicate things further, there are also ‘a’ and ‘b’ zones. Zone 3a is colder than Zone 3b.
When you look at the government of Canada site, you will see zone dates from 1961-1990 and then an update of 1981-2010. In most cases, zones have moved by at least half a zone. In 2024, Natural Resources Canada was to release an updated version. At press time, I did not find an update.
Plants are described as being hardy to a zone #. If a plant is listed as zone 6, it will survive in Zone 6 or higher. If you live in Zone 4, and try to grow and overwinter a Zone 6 perennial, you will probably not be successful. You are better off to look at lower numbered zones from what your area suggests, to be sure a plant is going to survive and be robust.
Reading plant labels and buying plants that are zone appropriate will help you to have more overwintering success. You will notice on most labels the zone is the USDA system. The label may say “perennial” but look at the zone. A plant can be a perennial…..but only in Florida (Zone 8 or higher).
Other factors for overwintering success include snow cover, wind, and humidity. Snow cover is a great insulator, wind can cause windburn, humidity will help plants stay hydrated.
With climate change happening, our Peterborough area has changed from 5a to 5b which means our average annual minimal temperature has moved from -26.1C to -23.3C.
Below are some towns and cities and their current zones:
Bancroft – Zone 4a ( interesting to note, this zone did not change in the update)
Haliburton – Zone 4b
Port Hope – Zone 6a
Pickering – Zone 6a
Hamilton – Zone 6b
Thunder Bay – Zone 3b
Lakefield, Lindsay, Norwood, and Ennismore are all the same as Peterborough’s – Zone 5b
Things to Remember
Canadian and American systems are not the same. For instance, Zone 5 under the USDA system should be considered Zone 6 in Canada
You can stretch the zones, if you have a micro climate or spot protected from wind, good snow cover and a milder winter
So depending on your gardening confidence, you can stick to Zone 3 or 4 perennials for zonal success or be adventurous and try that beautiful Zone 6 perennial. Just remember to read your labels and check your zones.
Flowers planted in a vegetable garden aren’t just beautiful, nor just an edible addition to your salads, and not even just a pollinator attractant for your zucchini crop. Did you know that specific flowers that attract beneficial insects by providing pollen and nectar resources, known as insectary plants, are one part of the botanical triad preventative pest management approach used by organic farmers that you can apply in your own garden? The other two parts of the triad are the desired crop (vegetable or fruit) and a trap crop that is more attractive to insect pests than the desired crop, hence luring pest populations away. The trap crop once infested with pests is sacrificed.
Field trials have demonstrated that planting both insectary plants and trap crops is more effective at reducing pest populations than using either method alone (i). Researchers are developing guidelines for the most effective triad plant combinations for a localities’ pest and beneficial insects. Additionally, they are testing optimal planting arrangements, for example, planting insectary plants along field edges and inter-planting trap crops with the desired crop.
In Quebec, researchers evaluated 10 different flowering plants for how well they attracted both (i) beneficial natural insects and (ii) typical insect pests. Weekly surveys found that beneficial ladybeetle (Coccinellidae family) captures were twice as high in Marigold (Targetes patula), Nasturium (Tropaeolum majus), Cosmos (Cosmos bipinnatus) and Common Yarrow (Achillea millefollium) as compared to the other six plants in the study. Meanwhile, captures of Tarnished Plant Bugs (Lygus lineolaris) pests were highest in Bee (or Lady) Phacelia (Phacelia tanacetifolia) while flea beetle pests (Chrysomelidae: Alticinae) were highest in Sweet Alyssum, White Charlock (Sinapis alba), and Marigold (ii).
Trap crops can be in the same family as the desired crop, but have to be more attractive to the pest. For example, in one study 10% percent of the Broccoli crop area was interplanted with the Brassica, Pac Choi to effectively lure away flea beetles (iii). Similarly, Blue Hubbard Squash, susceptible to Squash Vine Borer (Melittia cucurbitae), Squash Bug (Anasa tristis), and spotted and striped cucumber beetles (Diabrotica undecimpunctata, Acalymma vittatum), is used by commercial farmers as a trap crop when growing other squash, cucumbers and melons (iv).
Home gardeners can apply the botanical triad by interplanting trap crops and insectary plants in their vegetable gardens.
The Pac Choi trap crop is more attractive to flea beetles than Broccoli. Once flea beetles feed on Pac Choi they can easily be controlled by other means, for example, tilling the infected Pac Choi into the ground (Photo used with permission from Dr. Joyce E. Parker, The University of Sydney).
Trap Crops
Planting a diversity of trap crops is more effective than planting only one trap crop species. The trap crop should cover at least 10% of the desired crop’s planting area to be effective, and must be destroyed to kill the pest before it moves to the desired crop (iii). A few trap crops that have been found to reduce insect pests on common vegetable crops follow.
A few studies have found that basil and marigolds effectively reduced thrip and tomato hornworm populations in tomatoes (v). The author planted a few basil (in all 4 corners of the raised bed) and marigold plants into this tomato bed.
Insectary Plants
Flowering annuals like Marigold, Nasturtium, Cosmos, Bee Phacelia and Sweet Alyssum can be started indoors before transplanting the seedlings into vegetable gardens after the frost-free date. These will flower within a month and be able to feed beneficial insects, when pest populations peak and right into late fall. Planting a succession of native flowering plants near the vegetable garden can also provide habitat for beneficial insects as well as support pollinators.
These annuals can be purchased in garden centres, but are often only available as varieties with double flowers that either produce less nectar (because energy is put into petal production) or block pollinator access to nectar and pollen (vii). Choose single or heirloom varieties to maximize pollen and nectar for beneficial insects. It is also more economical to start your own plants, because you can be certain they haven’t been treated with synthetic pesticides. After all you want to attract beneficial insects that will in turn prey on or parasitize insect pests on your vegetables!
As you plan your 2025 vegetable garden, consider whether the botanical triad could help prevent or minimize any pest problems you may have experienced in the past.
Some flowers like Marigolds both attract beneficial insects and trap pests, here helping to protect the Armenian Cucumber in the author’s garden. The Sweet Alyssum in the bottom left corner (and elsewhere in the garden) has also been found to be both an insectary plant and a trap crop (ii).

Last night I dreamed of green, lush tropical gardens. It was yet another sign I am suffering from the February winter blues or as I call it “Garden Deficit Disorder”.
Yes, the days are getting a little longer with every sunrise, and we have had a fair bit of sun over the past month (which helps a lot) but I have more than half a metre of snow blanketing my gardens while my English cousins are sending photos of snowdrop drifts after their ‘long winter’.
I do like the winter season, if for no other reason than my aging body needs a rest from the garden. But it’s also the only downtime I have to plan for next year’s garden, order seeds and attend garden workshops, because I know once spring arrives I will not have a minute to spare.
So I’ll offer up a few gardening related activities for the wintertime that may help you through the blues…
Browse those Seed Catalogues
Whether you get paper copies or just look at them online, seed catalogues will bring a smile to your face, even if you don’t buy anything. The wonderful folks at Seeds of Diversity have put together an great map of Canadian seed companies. Some of my favourites are Northern Wildflowers (Sudbury), William Dam Seeds (near Dundas), Floribunda Seeds(near Peterborough) and Hawthorn Seeds (Mount Forest).

Catch Up on Your Reading
Winter is the only time (and my favourite time) to cuddle up with my newest garden book, while enjoying beautiful photos and deciding which new plants will be my garden next year.
If you’re interested in native plants I highly recommend The Gardener’s Guide to Native Plants of the Southern Great Lakes Region (I did a book review here) and A Northern Gardener’s Guide to Native Plants and Pollinators: Creating Habitat in the Northeast, Great Lakes and Upper Midwest by Lorraine Johnson.
Another favourite I’ll be drooling over (it’s visually stunning) is Planting – A New Perspective by Piet Oudolf and Nigel Kingsbury.
Or even a fictional book involving gardening makes me happy – highly recommend The Last Garden in England by Julia Kelly.
Buy a New Houseplant (or 2, or 10)
While I love seeing colourful houseplants over the winter, our harsh interior conditions (furnace heat and low humidity) are not ideal for them. I will confess – I am a much better gardener outside than inside, plus I have the additional challenge of two cats that like to nibble. But do a little research and find the right plant for your space, or if you’re not ready for that investment, just pick up some fresh cut flowers to brighten your day.
Review your Garden Photos
On dull winter days I try to review and organize the zillions (ok maybe a slight exaggeration) of garden photos on my phone (I even have a gardening folder). I download the photos to my computer and organize them, all the while just enjoying the memories and seeing the colour! It’s wonderful that digital cameras and our smart phones now make it so much easier these days to capture our gardens in all their glory.
Here’s one of my chipmunks munching on some Green-headed/cutleaf coneflower (Rudbeckia laciniata) buds this summer.
Attend a Seedy Saturday or Sunday
If you’d like some more social interaction with likeminded gardeners or even just some advice, finding a local Seedy Saturday or Sunday is perfect. They occur across Canada, mostly in February and March. Seeds of Diversity have a comprehensive list– use the menu on the right of the page to filter by province. Peterborough’s Seedy Sunday is March 9th.
Find Gardening Seminars (online or in person)
If I can think of anything positive about the pandemic, it’s that we all transitioned to more online learning, and platforms like Zoom made it easy for garden experts to reach large audiences. While it’s always wonderful to see speakers in person, online presentations mean I can watch gardening experts that I might otherwise never have the chance to see in person.
Our Grey County Master Gardeners offer a great series, as does Mississauga-based Blooming Boulevards, and I’ve also been attending the Home Gardening seminars offered by the Iowa State MG Programand some by the Wild Ones organization in the US.
An upcoming in-person gardening event in Peterborough is the very popular A Day for Gardeners – save the date!
Gardening Blogs and Websites
Personally I tend to follow those who have similar growing conditions to me (Zone 4b, harsh winters, Central Ontario) but I do have several (including a few in the UK) which I like to just view and enjoy.
You should of course sign up to receive the weekly Peterborough Master Gardener blog, delivered straight into your email on Monday mornings. Our members cover various topics and issues which will be of interest to gardeners, and you can also search older blogs for specific information using the search function.
Here are a few of my favourite blogs/newsletters. Many of these folks also have YouTube channels and extensive information on their websites.
Although the article alluded to its use as a food source for critters, that wasn’t the main purpose of the article. In this blog, I’d like to expand on that initial description to provide more information on the importance of the tree to our mostly four-legged friends and planet co-habitants.
The eastern white cedar (Thuja occidentalis), common in forests and along shorelines, provides a reliable food source for many animals when other options are scarce during our harsh winters. I have a row of cedars at the back of my lot mostly for wind control but it provides other functions for local wildlife.
Deer are among the most frequent consumers of cedar during winter. When snow covers ground vegetation, deer browse on cedar foliage, which is rich in nutrients. This evergreen tree helps sustain deer populations, especially in areas with limited winter food. However, over-browsing can damage young cedar trees and affect forest regeneration.
Other animals also rely on cedar. Snowshoe hares feed on cedar bark and twigs when their preferred food sources, like shrubs, are unavailable. Porcupines chew on cedar bark for nourishment. Even small birds, such as chickadees and finches, eat the seeds found in cedar cones.
Cedar trees provide shelter. Their dense, evergreen foliage offers protection from wind and snow, creating warm habitats for birds and small mammals. This shelter can be as important as food for survival in winter.
If you own land with cedar trees, consider their value to wildlife. Protect young trees from over-browsing by using barriers or planting more cedars in areas where they are heavily used. Maintaining healthy cedar stands can support local ecosystems and provide crucial resources for animals during winter.
In addition to cedar, deer and other wild animals rely on a variety of other trees, shrubs, and woody plants for food. These sources are critical when grasses, green plants, and other ground vegetation are buried under snow. Below are some examples:
Trees Consumed by Deer
Aspen and Poplar (Populus species): Deer often browse the twigs and bark of these trees, especially younger specimens.
Maple (Acer species): Deer will eat twigs and buds from sugar maple and red maple trees.
Birch (Betula species): Twigs and bark of birch trees can be a winter food source.
Hemlock (Tsuga canadensis): Eastern hemlock is a favorite winter food, with deer browsing its soft, green needles.
Willow (Salix species): Willows near wetlands provide twigs and bark for deer and other animals.
Oak (Quercus species): Acorns, if not consumed in the fall, remain an important energy source for deer and squirrels during winter.
Other Trees and Shrubs for Wildlife
Alder (Alnus species): Twigs and catkins are eaten by small mammals and birds.
Pine (Pinus species): Seeds from pine cones are consumed by squirrels and birds, while deer sometimes nibble on needles.
Dogwood (Cornus species): Red osier dogwood is a common browse species for deer and rabbits.
Sumac (Rhus species): Deer eat sumac twigs and fruit clusters during the winter.
Apple and Crabapple (Malus species): Wild or abandoned apple trees provide fruit, twigs, and bark for wildlife.
Conservation Tips
To support wildlife during winter, maintaining diverse tree species in forests and natural areas is crucial. Planting native shrubs and trees that produce berries or nuts can also help sustain wildlife through the cold months.
With the new year days away, resolutions for 2025 might be on your mind. Here are a few easy garden practices you might want to include in those New Year’s Resolutions.
Keep a record.
Have a file, record on your computer, write in a journal, put plant tags in a zip lock bag by year. Write on your tags the year & where you planted. It is important to know which hydrangea you planted, so if you need to research how to prune or how large it should get or if you want to purchase another, you will have that information. When you keep tags or record what annuals you plant, if it is something you want to repeat, you will have the exact variety when you go shopping the next spring. There are so many varieties of so many plants.
Keep things clean.
Disease is often spread through the tools we use. Have a pack of wet wipes in your tool box & clean tools after each use. Sharpen tools at the end of gardening season, so they are clean & ready to go in spring. Although you should use leaves as compost, don’t leave diseased plants in your gardens. Place them in your green garbage. Keep houseplant soil free of fallen leaves as well.
Keep yourself healthy.
Stretch before going into the garden to do manual work. Limit yourself to an amount of time that is good for you and your body and stop when your time is up….your garden will be there when you come back. Take your water bottle with you. Wear gloves & hat to protect yourself. Don’t work in the blazing sun…. bad for you & your plants.
Do your research.
Right plant in the right spot will give you more chance of success. If you plant a water loving perennial in a dry sandy spot, the plant will suffer or fail. Planting a tall annual at the front of your bed will obscure the pretty ones behind it. Use the internet, but make sure you are using reputable sites where knowledgeable gardeners are sharing good information. Look for articles written by Master Gardeners or university professors or scientists. Look for websites that end with “edu.” You can also contact Peterborough Master Gardeners online (peterboroughmastergardeners.com) to ask questions or check out what events we will be at in 2025.
Enjoy your gardens.
Remember, you garden because you get enjoyment from your hard work. Wander through your garden, peaking at the new sprouts coming up or the gorgeous flowers opening. Breath deep. Enjoy the birds, insects and wildlife that visit. Research shows that gardening and being in nature help our minds, bodies & souls.
Happy New Year! From Peterborough Master Gardeners
Last April, I wrote an article entitled “How do my outdoor plants survive the winter?” Although not as popular a subject topic, a quick dip into the world of all things creepy crawly when the temperatures plummet may be of similar interest.
When winter hits our region, we head indoors, but what about insects? These creatures have incredible ways of making it through the cold winter months. So much for my favourite October joke: “What’s the best thing about October? The mosquitoes are dead.” True, but also not for long.
Some insects, like ladybugs and cluster flies, find shelter and enter a hibernation-like state called diapause. They slow their bodies down to a near standstill, using very little energy while tucked away in cracks, under leaves, or even in homes. Those sneaky lady beetles seem to be able to find a way into houses too!
Other insects, like woolly bear caterpillars, use natural antifreeze. Their bodies produce special chemicals called cryoprotectants, which prevent their cells from freezing. This allows them to survive temperatures well below zero.
Some insects, like mosquitoes, leave behind their eggs, which are tough enough to endure the cold. Come spring, these eggs hatch, and a new generation begins. Sigh. Similarly, some butterflies, like the Mourning Cloak, overwinter as adults in tree bark or woodpiles, waking up early in the spring.
For honeybees, survival is a team effort. They cluster together in their hives, shivering their bodies to create heat and keep the colony warm.
And then there are insects like crickets, which die off in the fall, leaving behind their eggs to carry on their legacy.
Winter may seem quiet, but beneath the snow, insects are surviving in remarkable ways. Whether through hibernation, antifreeze, or teamwork, our local insects prove how tough and adaptable nature can be—even in the coldest months. For some, like pollinators, that’s great news. For others, like the red lily beetle, the Japanese beetle, and aphids, we simply have to grin and bear it.
As we celebrate Thanksgiving this year, we should think about what we are thankful for in our gardens. I recently asked my Master Gardener friends to share what they are thankful for.
Rainfall – Everyone was happy with the amount of rain we received this year. According to the Canada Weather Stats website (peterborough.weatherstats.ca), our rainfall for the period from July 2023 to June 2024 was over 100mm more than the same months in the previous year. And we seemed to have it at the right times. Although rain is great, it is important to remember that watering still needs to be done, especially containers of annuals and vegetables and hanging pots. When plants get big and fill the pots, the rain may not get down into the soil which is where you want the moisture to go.
Good educational information – As Master Gardeners, we use scientifically-based resources for answering gardening-related questions. Use the extension “.edu” or “.sci” in the search box when you are googling. There is so much information out there, but we need to be sure it is the correct information. Master Gardeners are always asking questions, learning and sharing their knowledge.
Healthy Gardens – Feeding the soil is a big part of having a healthy garden. Putting good quality topsoil in a new garden area, and adding organic compost annually will help your soil. Mulching holds the moisture and suppresses weeds. Leaves are great for mulching on your perennial beds. Free local wood chips supplied by Ontario Hydro were a great mulch for one gardener.
Good Harvests – Vegetable gardens were bountiful this year. Thanks to an exceptional harvest of peppers, tomatoes and beets, there are stuffed peppers in the freezer, tomato sauce and salsa and pickled beets in the cupboard. Carrots and brussel sprouts grew well and herbs like parsley and rosemary were huge and healthy. One gardener reported two butternut squash plants produced 20 squash!
Beautiful Flowers – With all the rain and heat, hostas were huge, sunflowers towering, clematis bloomed long and luscious. Everything seemed to be big and beautiful and most bloomed earlier and longer than normal. Container annuals like coleus grew huge and healthy.
Nature in the Garden – Master Gardeners actively promote native plants in the garden to encourage more pollinators. Integrating natives amongst your cultivars works well if you don’t want that ‘wild’ appearance many natives provide. Several gardeners reported visits from birds like Chickadees, American Robins and House Wrens that made their nests and raised their babies in their gardens. Cedar Waxwings, White-Throated Sparrows, Song Sparrows, Dark-Eyed Juncos, American Goldfinches, Northern Cardinals, Hairy Woodpecker, and a Common Yellowthroat came to visit and forage. Birds are great for the garden as they will eat many pests. And they give us enjoyment.
I am trying to be thankful for the skunk who has been visiting my yard and digging grubs. My yard looks like a minefield, but it is healthier!
What are you thankful for in your garden?
Happy Thanksgiving!
And thank you to MJ, Gladys, Carol, Laura, Chris, Jenn, Silvia, Cheryl, Deb, Grant, & Mary Kathleen.
As fall arrives, many gardeners notice an increase in earwigs lurking around their plants. These small, dark brown insects with pincers on their tails can look a bit intimidating, but their impact on your garden is a mix of good and bad.
Earwigs get their name from the old European myth that they crawl into your ears and tunnel into your brain to lay their eggs while you are sleeping. YIKES! Lucky for us, this old wives’ tale is not true. But the pincers on the back on an earwig’s body are still enough to freak people out.
Earwigs are most active at night and can often be found hiding in damp, dark spots during the day. In the fall, they seek shelter from the cooler weather, often in garden beds, under mulch, or in piles of leaves. While earwigs have a bad reputation for munching on plants, their role in the garden isn’t all negative.
On the downside, earwigs do eat leaves, flowers, and vegetables like lettuce, strawberries, and soft fruits, which can cause damage to your garden. However, they don’t typically cause significant harm unless their population is out of control like in a season that’s wetter than normal.
On the positive side, earwigs help clean up the garden by eating decaying plant matter and even feeding on pests like aphids and mites. This makes them useful in keeping some pest populations down naturally. Earwigs will even eat other earwigs!
If you find earwigs causing damage, there are simple ways to manage them. Traps made from rolled-up newspaper or damp cardboard can attract them overnight. In the morning, simply dispose of the traps.
While earwigs can cause some harm to plants, they also play a helpful role in garden cleanup and pest control, making them a creature worth understanding in the fall garden ecosystem.
