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.
Ensure the plants closest to your home are those that hold moisture. Succulents are a an example. Also, clear dead plant material and other burnables away from your home and other structures. Simply living in the suburbs is no guarantee against fire loss. Be sure to use fire safe gardening methods.
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 layer 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. Planting 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 you can get 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 plant families:
• Allium - white, yellow and red onions, leeks, shallots, scallions and garlic
• Apiaceae - caraway, carrots, celery, fennel, lovage and parsley
• Brassicaceae - Bok choy, broccoli, Brussels sprouts, cabbage, cauliflower, radish, arugula, collards, kale, and kohlrabi
• Amaranthaceae - spinach, beets, and chard
• Asteraceae (the daisy family) - artichokes, lettuce [Surprised you, didn’t I?]
You can set the stage for a lovely spring by scattering native wildflower seeds in autumn. Here, in the Bay Area, our winter rains provide the moisture needed for these seeds to germinate and grow. As winter winds down and temperatures begin to rise, your wildflowers will put on a spectacular show of color. This is also a good time for installing 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, lemongrass, marjoram, and sage to your herb garden for a tasteful gardening experience!
