my october garden chores

chores-logoFALL IS HEATING UP, at least visually, even as temperatures trend downward. Cleanup is (hopefully) under way in earnest, with time out to cook up the last bits from the vegetable garden into a batch of ‘Tomato Junk’ or soup, or local apples into applesauce, checking on the kettles between rounds of raking and cutbacks outdoors. With such delicious reminders of summer and fall in the freezer, and the right plants in the garden, there’s no “end” to fear. Some of us even feel happy about the coming riches: berries and other fruits, bark, new birds.

Peak planting time for bulbs and for many woody things continues through month’s end or so; make that work include some focus on the addition of fall and winter plants to the landscape.

Garden cleanup, though, is the primary order of the day—and don’t forget: quickly stash your tender things as frost threatens or just after, depending on the plant, to carry them through the winter. Here we go:

TREES & SHRUBS

CLEAR TURF OR WEEDS from the area right around the trunks of fruit trees and ornamentals to reduce winter damage by rodents. Hardware cloth collars should be in place year-round as well.

BE EXTRA-VIGILANT cleaning up under fruit trees, as fallen fruit and foliage allowed to overwinter invites added troubles next season. So will mummies (shriveled fruit hanging on the trees). Best to pick and remove (though I confess to leaving mine hanging for the birds, who adore it).

SCOUTING FOR VIBURNUM BEETLE begins later this month, when leaves fall and their egg cases are easier to see. Remove egg cases by pruning off affected wood, between then and April-ish, to reduce larvae and beetle issues in the coming year. The bump-like cases are usually on the underside of youngest twigs. I also watch in May for larvae hatch and rub the twigs then to squash the emerging pests.

BE SURE TO WATER trees now through hard frost if conditions are dry, 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 otherwise.

DON’T PANIC IF EVERGREENS continue to show some browning or yellowing of needles this month and next. The oldest, innermost ones typically shed after a few years on the tree.

ALWAYS BE on the lookout for dead, damaged, diseased wood in trees and shrubs and prune them out as discovered. This is especially important before winter arrives with its harsher weather, where weaknesses left in place invite tearing and unnecessary extra damage. Remove suckers and water sprouts, too.

VEGETABLE, FRUIT & HERBS

DID YOU SOW COVER CROPS? Green manures help build soil tilth and fertility. There are varieties for each season and region; I use winter rye and medium red clover through mid-fall here.

PREPARE A SEEDBED NOW for peas and spinach for next spring, to get a headstart on such early crops. Spinach can even be sown now through Thanksgiving, for super-early spring harvest; not the peas, of course.

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.

PARSLEY AND CHIVES can be potted up and brought indoors for offseason use. A few garlic cloves in a pot will yield a supply of chive-like (but spicier) garlic greens all winter for garnish. Determined types with really sunny windowsills can sow seeds of bush basil in a pot, too. I rely on frozen pesto cubes instead. I also freeze a lot of green herbs, from sage to parsley, this way.

IF NEXT YEAR’S GARDEN plans include a patch of strawberries or asparagus or cane fruits like raspberries, do the tilling and soil preparation now so the bare-root plants ordered over the winter can be planted extra early come spring.

REPLANT YOUR BIGGEST CLOVES from your best heads of harvested garlic for best yield, or hurry and order a supply and plant now (about a month before frost is in the ground). 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. The whole story is here.

FLOWER GARDEN

PAY SPECIAL ATTENTION to areas to cleanup around peonies, roses and other flowers that are prone to fungal diseases; don’t leave any debris in place.

CANNAS, DAHLIAS AND OTHER tender bulb-like things including elephant ears need to be dug carefully for indoor storage. There are many methods, but the basics: Once frost blackens the foliage, cut back the tops to 6 inches and dig carefully, then brush or wash off soil and let dry for two weeks or so to cure. Stash in a dry spot like unheated basement or crawl space around 40-50 degrees, in boxes or pots filled with bark chips or peat moss.

DON’T COMPLETELY DEADHEAD FADED perennials, biennials and annuals if you want to collect seed (non-hybrids only) or wish to let them self-sow for next year’s show. Nicotiana, poppies, larkspur, clary sage and many others fall into this leave-alone group; some plants must be left in place or seeds shaken around during cleanup to insure the next generation. Plants with showy or bird-friendly seedheads, like coneflowers, also get a stay of execution.

LAST CALL FOR BULB ORDERS (see Sources), and plant as they arrive (lilies most urgently). Remember our “early, middle, late” mantra when ordering. And think drifts, not onesies and threesies.

PREPARE NEW beds for future planting by smothering grass or weeds with layers of recycled corrugated cardboard or thick layers of newspaper, then put mulch on top.

HOUSEPLANTS

START A FIRST POT of paperwhites, and stagger forcing more every couple of weeks for a continuing winterlong indoor display.

REST AMARYLLIS BULBS by putting them in a dry, dark place where they will have no water at all for a couple of months. In September, I put mine in a little-used closet; do it now if you haven’t.

IF HOUSEPLANTS NEED repotting, do it before they come inside (less messy than in the house!). Ideally, I do this in spring just as they go outside, but if someone’s in need, do now. 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.

LAWNS

KEEP MOWING TILL THE GRASS stops growing, and make the last cut a short one. Let clippings lie on the lawn to return Nitrogen to the soil, unless they are long and wet, in which case, rake and compost.

COMPOST HEAP & MULCH

START A LEAVES-ONLY PILE alongside your other heap as a future source of soil-improving leaf mold, or when partly rotted for use as mulch. Running over dry leaves (and other dry non-woody material) with the mower to shred will reduce the area needed for such piles.

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 in fall. I’ll recut the messiest of my bed edges, too, if there is time.

Note on using this list: All chores are based on my Zone 5B Berkshire/Hudson Valley location; adjust accordingly.

    I would like to add some shredded paper to my compost pile, but I don’t know if printer toner is toxic. Anyone know? Any thoughts?

    • says

      Welcome, Amy. All toners are not made from the same ingredients, nor are all printer papers (some are bleached and so on, or coated); probably better to put this out with the recycling, no? That’s what I do; I would not compost office paper. Hope to see you again soon.

    Margaret,
    Help! The phlox, rudebeckia and peonies that share a bed all have a powdery mildew on their leaves. The same plants in other areas of garden are OK. Is it contagious across plants? Should I cut them all back to the ground now?

    Thank you,
    Mary Jane

    PS That’s a very handsome October frog.

    Hi Margaret
    Thanks as always for your lovely blog. I thought my lovely yellow cedar was dying but now know those brown needles don’t necessarily signify disaster, should I cut out the brown inner branches or leave them to fall off? I read your posting on hellebores but keep having bad luck with them. Is it too late for planting some more in my Zone 5B garden.
    thanks
    Liz

    Hi,
    Thanks for these reminders! In terms of leaf disposal, I want to start a new bed along a fence, using your cardboard method (it’s grass/weeds now). Would it make sense to rake all the leaves to along the fence and then mow over them to promote decomposition, and then lay cardboard over them? And then would I need to put something like mulch over the cardboard? Or should I put the cardboard down then the leaves over them? What’s the best way to do this?

    Thanks so much,
    Another Margaret

    Such a good idea to get a seed bed ready for spring sown spinach. That way you don’t have to worry about working the soggy spring soil! I’m totally going to do that this weekend.

    @Mary Jane: I’d cut them all to the ground and remove all the debris, raking up well and so on.

    @Liz: I sometimes rub off the brown needles where it’s unsightly, just using my hand (such as on a shrub in a prominent spot), but I’d be careful with pruning. Check carefully to see if it’s really the twigs that are dead, or did they just lose those older, inner needles? Sometimes it’s a mix of both; some dead wood (which you can cut off anytime it occurs) and mostly just the natural shedding of old foliage. As for hellebores, I moved some earlier in September and would still plant ones from nursery pots, but might not dig up any of my old, big plants this late to start dividing.

    @Another Margaret: The leaves will amount to very little once you shred them with the mower, so I’d make a huge pile near a site where you can compost them awhile after shredding. They will probably blow away if shredded and used right away as mulch. I’d use the cardboard on the new areas, and then a nice mulch like composted shredded bark or stable bedding that’s been aged (ask at your local nursery what composted, medium- to fine-textured mulch they have).

    Your readers with late season herb and vegetable gardens may well find that they will grow more than they can use, preserve or give to friends.

    They may want to visit http://www.AmpleHarvest.org – a site that helps diminish hunger by enabling backyard gardeners to share their crops with neighborhood food pantries.

    The site is free both for the food pantries and the gardeners using it.

    More than 945 food pantries nationwide are already on it and more are signing up daily.

    It includes preferred delivery times, driving instructions to the pantry as well as (in many cases) information about store bought items also needed by the pantry (for after the growing season).

    AmpleHarvest.org enables people to help their community by reaching into their back yard instead of their back pocket.

    Lastly, if your reader’s community has a food pantry, they should make sure the pantry registers on http://www.AmpleHarvest.org. Its free.
