12/9/16: In the garden this week


The garden is waiting for spring: male catkins of native hazelnut (Corylus americana) are fully formed, ready to release their pollen in early spring.

If you’re like most people, you’re too busy this time of year to do many gardening chores. Lucky it’s a quiet time: leaves are finally gathered, garden cleanup is complete (or should be), it’s too late to work on the lawn and too early to prune. But there are always things you can do in the garden:

water new plantings: in any week in which we receive less than an inch of rain (like this past week), water all plants installed this spring or fall. Perennials planted last season should be well-established, but those planted this year need supplemental watering during dry spells. How do you know when we’ve received an inch of rain? I use a highly sophisticated rain gauge–an old yogurt container placed on the ground among the plants. A tunafish or catfood can works equally well. I total the weekly rainfall and decide whether to water my new trees or my clients’ new plantings this week. This past week we received only about 3/4 inch of rain.

clean up the vegetable garden carefully: remove the spent plants; compost healthy ones, but throw out infested or diseased plants to prevent the spread of disease.

extend a garden bed or start a new one (it’s always a great idea to eliminate some lawn): spread a 3-4” layer of cedar or hemlock bark mulch over the area to kill the grass. Or use a thick layer of leaves (12″ or more). You’ll be able to plant right through the mulch and thatch next spring. You can scatter seeds in the mulch as you collect them.

collect seeds. Seed of purple lovegrass and of little bluestem is disappearing fast, because the birds love them both. Seeds of all prairie perennials are ripe. Right now it’s hard to keep up with the seed collecting. And plenty of seed will remain for the birds to eat this winter. I can’t go out the backdoor without disturbing flocks of goldfinches, and the bluejays become quite annoyed. Mixed-species foraging flocks have formed to take advantage of the bounty.

don’t clean up the perennial garden: leave the plants until spring. The birds will enjoy the seeds all winter, and the dead stalks will be easy to remove in spring.

— plan for next season: Do it now, while the garden is still growing. Notice things that did great and things that didn’t, make lists of areas you want to improve, areas of lawn you could get rid of, places that are getting sunnier or shadier and need new plantings to suit. Do you have enough fall color in your garden? If not, plant some colorful native shrubs in the spring.

work to protect the environment. Most Americans want clean air and water, are concerned about climate change, and want the government to work to mitigate it. When something happens in opposition to your basic environmental values, speak out. Write to your elected representatives, donate to an environmental organization, volunteer, march–there are many ways to make your voice heard.

In the rush of holiday preparation, take time to enjoy the garden!
