my garden chores: september 2011
TYPICALLY THE SEPTEMBER CHORES would be following the hottest, driest part of my garden year here—the summer—and I’d harp on about making sure to water your trees and shrubs right through when the ground freezes. I think with more than 7.5 inches of rain falling here on Saturday-into-Sunday alone, I might skip that step, and get on to the rest of the month’s chores, starting tomorrow with—yes!—weeding instead.
THE FALL IS COMING, the fall is coming. Nothing to worry about, Chicken Little, if the garden’s been planned for enjoyment in all seasons…well, unless you slack off now and let those foxy weeds go to seed and gobble up the whole place. No, no definitive “end” to the season lies ahead, and some of us even feel happy about the coming of slightly quieter, more contemplative times where less obvious garden stars can shine.
PEAK PLANTING AND DIVIDING time is upon us; make that work include some focus on the addition of fall and winter plants to the landscape.
Maybe something gold?
AS YOU BEGIN to wind down and clean up, take notes of what worked and didn’t. Mark areas that would have been easier to maintain with a workhorse groundcover in place, for instance, or areas where more bulbs might fit. Last year at this time I made a walkabout and identified various shrubs whose days were numbered; just not enough bang for the buck (well, for the space they take up), or simply too big to fit where they grew anymore. Down and out they came early this spring.
TREES & SHRUBS
IF YOU’RE ON THE DRY SIDE, unlike me, be sure to water trees and shrubs now through hard frost, so that they enter dormancy in a well-hydrated state. Evergreens (needled ones and broadleaf types like rhododendron, too) are particularly vulnerable to desiccation and winterburn if not well watered before the cold and winds set in.
HOPEFULLY YOU STOPPED FEEDING woody plants in July or August. Promoting more soft growth after July-ish isn’t good; time for them to start moving toward the hardening-off phase of their cycle. No more eats till earliest spring.
ALWAYS BE on the lookout for dead, damaged, diseased wood in trees and shrubs and prune them out as discovered. Ditto with suckers and water sprouts. No hard pruning now, though; too late to risk encouraging regrowth.
VEGETABLE, FRUIT & HERBS
AS VEGETABLE PLANTS (and annual flowers) fade, pull them to get a start on garden cleanup. Before composting the remains, cut them up a bit with a pruning shears or shred, to speed decomposition. That said, my earliest crop of lettuce each spring comes from a ‘Black Seeded Simpson’ plant I just let flower and self-sow in a corner of the garden year after year. Untidy to some eyes, but it always makes me smile.
MY FALL VEGETABLE GARDEN PLANS were covered in this archive story and podcast.
AS AREAS COME EMPTY from harvest, build vegetable-garden soil by sowing cover crops. These “green manures” will be turned under to improve soil tilth and fertility. Remember not to sow in areas reserved for fall-planted crops like garlic!
PARSLEY AND CHIVES can be potted up and brought indoors for offseason use, or freeze some (or give the plants some extra protection and keep harvesting from the garden). A few garlic cloves in a pot will yield a supply of chive-like (but spicier) garlic greens all winter for garnish.
IF NEXT YEAR’S GARDEN plans include a patch of strawberries or asparagus, do the tilling and soil preparation now so the bare-root plants ordered over the winter can be planted extra early come spring.
IF YOU HARVESTED YOUR own garlic, save the best heads with the biggest cloves for replanting later this month or next (about a month before frost is in the ground). Otherwise, order bulbs now. Prepare a sunny spot, and plant each clove 1-2 inches deep and 6 inches apart in the row, with about 12 inches between rows. Green growth will happen this fall, which is great; don’t panic. It’s a hardy thing.
DON’T DEADHEAD FADED perennials, biennials and annuals if you want to collect seed (non-hybrids only) or plan to let some self-sow. Nicotiana, annual poppies, larkspur, clary sage and many others fall into this leave-alone group. So do plants with showy or bird-friendly seedheads, like coneflowers, some sedums, clematis and grasses.
DAYLILIES can be dug and divided as they complete their bloom cycle, right into fall, if needed.
PEONIES are best divided and transplanted in late August through September, if they need it. Remember with these fussy guys that “eyes” must not be buried more than an inch or two beneath the soil surface. Want more peonies? Now’s the time to order.
MANY POPULAR ANNUALS can be overwintered as young plants if you take and root cuttings now rather than try to nurse along leggy older specimens. Geraniums, coleus, wax begonias, even impatiens (to name just a few common ones), if grown in good light indoors and kept pinched and bushy, will yield another generation of cuttings for next spring’s transplants. Probably best to expend this effort and space on things you really treasure—an unusual form of something, not the garden variety.
PREPARE NEW beds for fall planting by smothering grass or weeds with layers of recycled corrugated cardboard or thick layers of newspaper, then put mulch on top.
RE-EDGE BEDS to make a clean line and define them. Don’t let them get overrun just because summer’s wound down. A clean edge makes a big difference.
REST AMARYLLIS BULBS by putting them in a dry, dark place where they will have no water at all for a couple of months. I put mine in a little-used closet.
IF HOUSEPLANTS NEED repotting, do it before they come inside later this month (less messy than in the house!). Don’t step up more than an inch (on small pots) or a couple (on large ones). Most plants don’t like to swim in their containers.
MID-AUGUST TO MID-SEPTEMBER is prime lawn-renovation and planting time in the North. Have you reseeded yet? Paul Tukey at SafeLawns [dot] org shared some overseeding how-to’s recently.
DON’T BAG OR RAKE clippings; let them lie on the lawn to return Nitrogen to the soil, right through the last mowing in late autumn.
COMPOST HEAP & MULCH
ORDER A SUPPLY of bulk mulch, which is cheaper than the packaged kind and also eliminates the waste of all those heavyweight plastic bags. Many local nurseries deliver. Top up mulch in all garden beds as they get cleaned up gradually.
DON’T LET THE HEAP dry out completely, or it will not “cook.” Turning it to aerate will also hasten decomposition, but things will rot eventually even if not turned. I extract more finished material and screen it each fall, to work into the gardens (and make more room for incoming fresh debris).
