10/7/16: In the garden this week


Is your garden still full of pollinators throughout October? If not, consider planting some late-blooming natives, such as asters, goldenrod, and boltonia. This garden feeds wildlife year-round.

Despite the depradations of hurricane Matthew (a mere thousand miles away), our weather continues warm and sunny. No storm in sight, no hint of frost, and most likely not a good year for fall color–you need both cold nights and sunny days for that. And still not enough rain.

Despite the lingering warmth, winter will surely come, and after winter will come another spring. Gardeners are all very sure of that. Here are some things you can do in your garden now to ensure a lovely spring next year:

water new plantings: in any week in which we receive less than an inch of rain, like this week, water all woody plants installed this spring or last fall. Perennials planted last spring should be well-established, but those planted last fall or this spring 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. Sunday and Wednesday are my watering days, and Igave my new trees and shrubs a good soaking.

continue to practice good horticulture with warm-season crops such as tomatoes, peppers, squash, eggplant, beans, corn, and cucumbers. This is particularly important as the season winds down. Monitor for insect eggs and larvae and remove them before infestations become serious. Throw out badly infested or diseased plants to prevent the spread of disease (do not compost diseased or infested plant material). Pick fall crops of cool-weather plants like lettuce, spinach, and peas.

— as tomatoes ripen their fruit, cut back on watering to avoid split fruits: provide no more than an inch of water per week. (If it rains, don’t water.) Keep removing suckers. Look at this post, this one, and this one for basic information about growing tomatoes.

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. You’ll be able to plant right through the mulch and thatch next spring. You can scatter seeds there as you collect them.

collect seeds. Seed of purple lovegrass and of little bluestem is ripe, as are seeds of nodding joe pye weed, penstemon, prairie onion, and monarda. Rudbeckia seeds are ripe when the birds start to eat them. I grow two species, and one is ripe but the other is not yet.

— follow a sustainable lawn care regimen: if you feel you must fertilize your lawn, best practice is to give it no more than two applications of slow-release organic fertilizer each season, around Memorial Day and Labor Day. As the weather cools down, it’s time to reseed bare areas. Be sure to keep those patches well watered until the grass is up. But if you have a place where grass won’t grow, plan to plant something that will, like shade-loving native perennials. Other lawn care tips: let the grass grow at least 3″ tall for maximum photosynthesis. 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.

Leave the Leaves this year: use your leaves as lawn fertilizer, as mulch, and as the basis for a compost pile. Read more here.

Enjoy the garden this week and always!


Milkweed seeds continue to ripen throughout the autumn. This is orange butterflyweed (A. tuberosa).


And where there are milkweed pods, there are milkweed bugs. They don’t harm the plants but they do cut down on seed production to some extent.
