What to do in the garden in September and October

No content available.

Like you, I鈥檓 harvesting vegetables and fruit from my garden and preparing for storage. This is also a great time for doing a little renovating in the perennial garden鈥攁s well as planting or dividing bulbs. The cool weather will keep me busy! Let鈥檚 talk about what to do in the garden in September and October鈥攂efore the ground freezes!

Harvesting and Storing Fall Vegetables

  • I just picked the last peas and snap beans, steamed them briefly and froze in bags for winter meals.  You can do the same with broccoli sprouts and Brussels sprouts.
  • Pick all green tomatoes on plants, too, when a frost is imminent.  Store them in a single layer on trays and platters at normal room temperature until they ripen.  You can be eating your own tasty tomatoes for Thanksgiving with luck.
  • Cut pumpkins and Winter squash from their vines, when stems are browning and tough.
  • Store that squash in a cool, dark area like a basement or closet. Wash the rinds with white vinegar and water first to clean off dirt and prevent rot.

  • I also plant more cold-hardy crops in early fall, including wonderful Asian greens and some roots and veggies. Plus, don鈥檛 forget garlic is best planted in early fall鈥攁ny time after the fall equinox! See how to plant garlic

Picking Apples and Pears

I鈥檓 picking tons of apples, Asian pears, and pears from my eight-tree miniature orchard. Those are ready to pick when lifting the fruit up at the stem resulting in the apple or pear separating from the tree.  Don鈥檛 worry if they are a bit underripe; they鈥檒l ripen in storage.  About half of what I harvest is donated to the local food bank. F!

Pears, regular and Asian, don鈥檛 keep long, about six weeks in the refrigerator.  I make pie filling from my extras and freeze it in individual pie-size containers.

Apples store much longer in cool, dark areas.  After you fill-up the refrigerator, put the remaining apples in the basement or a cold garage.  Many varieties will store for up to six months.  Apple butter and tarts to freeze are some of the ways I use up extra apples, too.

Le Nain Vert pears are nearly ready to pick.  This ancient variety lacks the typical pear shape, but it鈥檚 filled with plenty of flavor.

 

Planting Bulbs for Spring Blooms

Fall is the best time to plant bulbs that flower in the spring for root establishment. Invest in a better bulb for better flowers. Ensure you have well-drained soil. Amend poor soils by adding organic matter (peat, manure, compost).

When to plant?  鈥淭he simple answer is that bulb planting season starts once your soil temperature reaches about 55 degrees Fahrenheit,鈥 says Tim Schipper of Colorblends, a Connecticut-based flower bulb wholesaler. 鈥淭he problem is who knows what their soil temperature is?鈥 he adds.

He asked landscape pros on his website () that question and came up with this list of tips.

It鈥檚 time to plant bulbs when:

鈥all foliage has moved just past peak

鈥rickets no longer chirp

鈥irds start to group and depart

鈥ou start turning on the heat in your car

鈥he air smells of wood smoke

鈥rapes are ripening on the vine

鈥he hostas start to lie down

鈥he air has that organic, decaying leaf smell

鈥he dog moves from a cool to a sunny spot in the yard

鈥he kids start putting on their jackets without being nagged by you

I鈥檓 not ready yet to plant bulbs, due to a warm early October, but I can hardly wait until the kids put on their jackets!

Planting Shrubs and Trees

Early fall is a good time to plant container-grown or balled-and-burlapped nursery stock. Sometimes it鈥檚 difficult to find the right trees so start looking on the early side.

When you plant, some folks say to make the hole twice as big as the root ball; I don鈥檛 find that to be necessary but the hole does need to be wider than the ball. And plant at the same depth.  Do not bury trees! Find the root flare that comes out at base of tree which will give you an indication of the soil level of where the plant can be sitting.

Before I plant, I break up and loosen the soil and I really wet the whole down before you put the tree in. Take hose and in bottom of hose, turn on, and mud that tree in.

After you plant, don鈥檛 forget to water in to remove air pockets. And mulch to protect against large fluctuations in soil temperature and moisture. But never mulch right next to the trunk which invites critters and problems.

Planting and Dividing Perennial Flowers

As well as planting new perennial flowers, this is a good time to transplant and divide many perennials鈥攅specially those which flower in the spring and early summer including peonies, irises, lilies, bleeding heart, and lily-of-the-valley. You want to do this job 6 weeks before the ground freezes.

I will transplant when I鈥檝e discovered a perennial needs a different growing environment or doesn鈥檛 like where it鈥檚 growing. Only divide a perennial when all the growth appears on the outer edges, it doesn鈥檛 bloom as well, or the blooms are smaller than usual. This means your plant have overcrowded roots. Here are directions I鈥檝e always followed:

  1. Using a shovel, dig out as much of the clump of the perennial as possible along with the soil. Don鈥檛 break off the soil until later and do so very gently. If you are dividing the plant, once it is out of the ground, separate the crowns by cutting them with a sharp knife or shovel blade. Preserve as many of the roots as possible.
  2. Prepare the new planting spot or revive the old one by turning the soil at least 8 inches deep. Remove rocks, roots, and debris.  Add plenty of compost and some aged manure.
  3. Dig a hole that is 1.5 times as deep and wide as the plant鈥檚 roots. Build a firm mound of soil in the middle of the hole. Spread the roots over the mound so that the crown sits at or just below the soil line. Gently backfill the hole and pull the soil up around the crown just as you would a container-grown plant.
  4. Water the plant and keep it consistently moist until a hard freeze. Don鈥檛 bother with fertilizer as it will only encourage top growth, which takes energy away from the roots.
  5. Once the ground freezes, apply a 3-inch layer of mulch and you are done.

Digging Up Tender Plants 

Tender plants have to be dug up. They are too sensitive to cold temperatures.

I dig up tuberous begonia and caladium just before frost. Store in warm location 7 to 10 days so they dry and won鈥檛 rot in storage. Don鈥檛 overdo it or they will get too dry! Store by packing between layering in potting material like vermiculite or sawdust or peat moss. Store in a dark storage area that doesn鈥檛 get too cold.  Store at 45 to 50 degrees.

With dahlias, cut back 3 to 4 inches after the first light frost. Then carefully lift plants, leave as much soil attached to prevent breaking fleshy roots. Air dry for only a few hours; dahlias are very sensitive to drying.
Store at 35 to 40 degrees.

Cannas don鈥檛 need to be dug up until after a hard frost. Cut tops back to 4 inches, lift with spading fork, and air dry in warm spot 1 to 2 weeks. Roots don鈥檛 need covering. Simply place in shallow boxes. Roots are best stored at 45 to 50 degrees.

Controlling Fall & Winter Weeds

Don鈥檛 let weeds get hold late in the season.  If you are using a fall pre-emergent regime, continue into fall and winter. Don鈥檛 let weeds get a food hold! 

My organic solution for cleaned-out vegetable beds is cover crops. Plant by end of September. They鈥檒l control weeds, improve soil quality, and prevent erosion in wet months.

Bringing Outdoor Plants Inside

Bring outdoor plants back inside before night temps fall below 55 degrees F. Check and control insects BEFORE bringing plants into house or it will spread to other houseplants.

Houseplants will drop leaves adjusting to light. You could transition by put in a bright spot first. Water indoor plants less frequently, and discontinue fertilizer. 

If you鈥檙e cleaning out containers or pots, be sure to sterilize them before storing them to prevent the build-up of pathogens. Soak in solution of 1 part bleach in 9 parts water for a minimum of 10 minutes. Then, transfer to a solution of dish detergent and water to rinse. Use steel wool or a wire bristle brush to clean dirt from clay pots.

Testing the Garden Soil Now

Fall is the best time to do a soil test. I try to test every 3 to 5 years for fertilizer levels and needs. Fertilizers can cause lots of salt buildup. Contact your county cooperative extension for a free or cheap soil test or ask a garden nursery how it鈥檚 done.

You鈥檒l want to incorporate organic matter in the fall to let the organic organisms work the soil all winter, avoid getting waterlogged soil in the spring, and it鈥檚 easier than trying to do all the garden activities in the spring. Plus, soil prepared in fall will warm up faster!
