Orange-red leaves fall Torn from brittle stems, take flight Soon for winter sleep Bay Area Octobers are the perfect time to prepare for a lovely spring. This is the season for removing weeds, dead plants, and pest habitats. It is also the time to plant winter crops. Best of all, October is the perfect time to install your very own herb garden! Cooler temperatures and (hopefully) rain provide conditions needed for thriving winter vegetables, spring blossoms, and ongoing herbal culinary treats.
Bring out your dead! Tomatoes, peppers, squash, and many other garden fruits and vegetables are now at or near the end of their productive lifecycle. While tomatoes are technically a perennial, most tomato plants are treated as annuals. Rather than pulling spent plants from the ground and destroying soil microbes, it is far better for soil health to cut the plant stems and stalks off at ground level. This allows roots to die off slowly, in the ground, providing soil microbes with the time they need to adjust. Chop thick stalks into smaller pieces to improve your compost pile’s natural processes when adding last summer’s plant material to the pile. Fall flower care This is also the time to continue weeding and deadheading flowers. Removing blossoms properly allows flowering to continue for as long as temperatures allow. The only exception is roses. To encourage your rose bushes to enter a much-needed dormancy, it is better to start removing only the flower petals and leaving the rose hips attached to the stem. Be sure to dispose of seeded weeds, rather than adding them to your compost pile. If you are raising chickens, weeds with seeds make excellent forage. Prepare winter beds Collect fallen leaves from under fruit and nut trees, rose bushes, rhododendrons, camellias, and azaleas to prevent the spread of pests and disease and add them to your compost pile. Pine, juniper and oak do not need leaf litter removed. Add a thick later of mulch or aged compost on top of all your planting beds. This will help prevent erosion and add nutrients to the soil for next year. Legumes such as cowpeas or fava beans can also add nitrogen to the soil, as long as they are not allowed to go to seed. Bare earth should be covered with a thick layer of wood chips, which can be gotten for free from local tree trimmers. Wood chips prevent erosion, add nutrients, and slightly acidify the soil. They look nice, too! Spring bulbs & winter crops Nothing says spring like brightly colored bulbs emerging from the barren muck of winter. Now is the time to shop for those spring bulbs and put them in the refrigerator (not the freezer) for 6-8 weeks. Use a paper or mesh bag to allow the bulbs to breath. You will want to keep them away from apples, which emit ethylene gas and will cause the bulbs to sprout too early. If you already have bulbs or perennial flowers, this is a good time to dig them up and divide them to allow for better growth in the spring. In the Bay Area, autumn is the perfect time to winter crops from these plants families:
This is also a good time for planting spring wildflower seeds, as well as native plants, shrubs and trees. Create your very own herb garden! You can create an herb garden in your yard, on a balcony, or even inside your home. The following herbs and spices can be planted now to provide years of delicious meals and lovely displays, wherever they are grown: When spring comes around, you can add basil, anise, borage, oregano, lemon grass, marjoram, and sage to your herb garden for a tasteful gardening experience! Which plants are you putting in this October?

Cooling, shorter days Succulent harvest abounds Prepare now for cold Harvesting the fruits of all that labor and preparing for winter keep the September gardener busy. Deadheading, clearing away debris, and composting spent annuals all help to prevent future problems with pests and diseases. Apples Many apple varieties are ready for harvest (assuming the birds have left any uneaten). Other apple varieties will need some colder weather to sweeten. If you notice small brown, corky areas under the skin, it is called bitter pit. Bitter pit, like blossom end rot in tomatoes, is caused by a calcium deficiency early in the spring. In this case, however, the condition can be treated on future crops by spraying the leaves with calcium nitrate just after bloom and again one or two months later. Use one tablespoon per gallon of water. Carrots Carrots prefer loose soil, but shorter varieties perform well enough in our heavy clay. The addition of compost can help aerate the soil and provide valuable nutrients. Carrots should be planted no more than 1/2” deep and plants should be thinned to 3” apart, to avoid forking and twisting. Water regularly but allow some drying to prevent cracking. Successive plantings provides an ongoing harvest. Carrots can be planted between landscape perennials for productive use of space. Leafcutter bees If rose leaves are exhibiting neat round or oval holes in them, it is probably the beneficial leaf cutter bee and should be ignored. The sections of leaf are used to line brood cells, which are also filled with nectar and pollen. Mosaic virus Squash and cucumber plants are susceptible to a disease carried by aphids and cucumber beetles. Mosaic virus causes leaves to become mottled and stunts plant growth. Fruit may become white. Diseased plants should be removed and put in the trash. Do not add to the compost pile. Powdery mildew As nights become cooler, it is common for powdery mildew to strike. Affected leaves should be removed and thrown in the trash, and overhead watering should be avoided. Rats Gnawed fruit, empty snail shells, and tiny black pellets are all signs of roof rats. These pests can infiltrate your attic, crawlspace, garage, storage shed, and trees. Rat traps are an excellent way to remove resident rats. Keeping pet and livestock food sealed up and harvesting crops as soon as possible will help make your yard less desirable to the local rat population. Since rats can carry serious diseases and damage electrical wiring, it is worth the effort to get rid of rats. Spider mites If leaf stippling and tiny webs are seen, spider mites are probably the reason. Spider mites prefer dusty conditions, so spraying infested plants with the hose can help. Using broad spectrum pesticides is not recommended because they will kill the spider mites’ natural predators. Heavy spider mite infestations can be treated with insecticidal soap or horticultural oil. Vegetables September is the time to plant many winter crops, including artichoke, arugula, beets, bok choy, cabbage, carrots, cauliflower, chard, cilantro, collards, dill, fennel, kale, leeks, parsnips, peas, radishes, rutabagas, spinach, and turnips. Enjoy the fruits of your labor! |
