11/25/16: In the garden this week


To a human, this wintry border looks rather messy. To a bird, it’s a cornucopia of delights.

#GoOutside today! Garden, walk, hike, play a sport. Make it Green Friday, not Black. Avoid the malls. But don’t avoid good deals altogether: Prairie Nursery is offering 10 percent off on gift certificates from now through December 24.

If you feel like gardening, here’s are some suggestions:

Leave the Leaves this year: Don’t blow your leaves out to the curb; recycle them on your property. Fallen leaves and grass clippings represent the fertility of your soil, so why give them away? Use your leaves as lawn fertilizer, as mulch, and as the basis for a compost pile. Read more here.

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.

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.

— fall is the best time to 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 asters, joe pye weed, penstemon, prairie onion, and monarda 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 (see the photo above).

— follow a sustainable lawn care regimen: it’s too late to fertilize or reseed. If you did reseed this fall, keep the seeded area moist until the grass is germinated. But if you have a place where grass won’t grow, plan to plant something that will, like shade-loving native perennials. As the leaves fall, mow over them, don’t rake or blow them. Your mower will chop them into small pieces that will quickly disintegrate, returning valuable nutrients to the lawn. Established lawns do not need water now (or ever), but if you do water, do it infrequently and deeply to encourage deep root growth. One inch of water once a week is much better than a few minutes each day. But remember: the more you water, the more you’ll have to mow!

— 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.

Enjoy this holiday weekend, and enjoy the garden, and nature, now and always.
