Midwinter Tasks for Pollinator Gardening

It is mid-winter here in the Pacific Northwest and I’m cozily ensconced in my living room watching a steady rain come down. Once the rain slows, I will don my muck boots, grab a few tools and go play in the garden.

Winter seeding

Even in January there are small actions I can take to support pollinators. Last weekend, I used the unwelcome but increasingly common warm weather to plant seeds that my father-in-law collected from his yard (his holiday gift to me). While not all seed can be planted during colder months, White Brodiaea, also known as Fool’s Onion (Triteleia hyacinthina), supposedly can be planted at almost any time. I only planted some of the seed as an experiment. If successful, in a few years the bees in my garden will have a new source of late spring forage. The other seeds, including with selfheal (Prunella vulgaris) will have to wait. I’ll use that to overseed my “lawn” this spring, in quotes as the patch of grass is interspersed with clover, English daisy and violets.

Easy weeding

Winter is a good time for some basic maintenance tasks to help prevent pest pressure in my postage stamp vegetable and pollinator gardens. First up, getting ahead of the weeds that crowd out desirable plants. The warmer temperatures that allowed me to plant are also allowing the weeds to flourish. Since the ground is moist but not saturated, weeding is relatively easy (I can actually pull out dandelion roots) and none of the weeds have set seed, which means if I pull them now, I won’t have as many weed to contend with later.

I’ll admit, my tolerance for weeds is pretty high. That said, my neighbor works hard to avoid weeds so I spend extra time removing weeds that could spread to her yard. I also prioritize weeding in my pollinator garden as I don’t want less desirable plants to crowd out the many native plants that attract bees and butterflies to my yard. Fortunately, I don’t have to weed my vegetable garden as last October I planted field peas as a cover crop and that seems to have suppressed most of the unwanted plants from filling the space.

While winter gardening conditions vary around the world, it can be a productive time to upkeep your pollinator garden. Some items, like pruning and "do nothing" on wild areas and nesting sites, can be successful anywhere. (Photo: Matthew Shepherd / Xerces Society)

Deter indoor ants and other pests

Another task on my “to do list” is to deter ants from entering my home. My neighborhood is well known for nuisance ants. While I like having ants in my yard where they help aerate the soil and improve drainage, I do want to keep them out of my pantry. To do this, I’ll trim shrubs back at least a foot from the siding. This simple step removes a direct route for ants to enter my home since branches won’t be touching the house. I also avoided planting flowers that attract ants (e.g. clematis, peony and rose) next to my home.  The last task on my list is to prune the grape, something I’ll do a few times throughout the year to increase yield and ensure there is enough airflow so powdery mildew doesn’t get a foot hold.

Leave wild spaces for the “wee folk”

There won’t be any work to do in my side yard as I leave that area pretty untamed. There is an old rhododendron as well as asters and goldenrod that need little care to thrive. There are also some bare spots that I leave to entice ground nesting bees.  When I enter this space I can hear my mom telling me about my great grandmother Henrietta Waugh who taught my mom to “leave wild spaces for the wee folk.” Maybe the pollinators are the wee folk my great grandmother was referring to but I’m pretty sure her thoughts were of a magical bent. She was Welsh, after all.

One of the most valuable things you can do to support pollinators and other invertebrates is to provide them with the winter cover they need in the form of fall leaves and standing dead plant material. This bit of nature is essential to the survival of moths, butterflies, snails, spiders, and dozens of arthropods. (Photo: Deborah Seiler/ Xerces Society)

Each of the projects I am undertaking – planting flowers, avoiding chemical pest management and leaving undisturbed natural areas for pollinator nesting – are part of Xerces’ Bring Back the Pollinators Pledge, an easy and fun way to help conservation. The fourth step in the pledge is to engage others in the effort. To that end, like my father-in-law, I too save seeds that I share with friend and neighbors. My family laughs at me but I get a little thrill each time I visit a friend’s home and see plants that came from my yard. See for yourself, take the pledge and spread the word (and the flowers).

In that role, she has built a program focused on securing practices and policies that promote ecologically sound pest management. She and her staff evaluate the risks of pesticides, develop technical guidance, and advocate for actions that reduce reliance on and risks of pesticide use in both urban and agricultural settings.
