Maintenance
- Keep an eye on the weather report - protect frost-tender plants when the temperature falls below 32 degrees.
- Divide perennials like daylilies and chrysanthemums.
- Prune crepe myrtles, cane berries, and roses, and clean-up trimmings.
- Prune plum, pluot, apple, and pear trees 15-20%; cherries 10%; and peaches 50%.
- Mulch, water, and cover tender plants to protect from frost. Be sure to remove coverings during the day.
- Since flowers are scarce in most gardens now, it’s important to keep your feeder filled; clean and refill it every few days.
Trees, shrubs, perennials
- Bare-root deciduous shrubs and trees are available now.
- Plant your living Christmas tree. Be sure to plan for size at maturity.
Flowers
- Plant your bare-root roses.
- Continue to plant tulips, narcissus, daffodil, and hyacinths for a longer show of blooms in the spring.
- There’s still time to plant California poppies and seeds for other spring-blooming wildflowers. Choose a spot in full sun. Rake the soil slightly and water to dampen. Sprinkle seeds onto damp soil and rake gently, just enough to cover seeds. Unless it rains, continue gentle watering to keep the soil damp until seeds sprout.
Vegetables
- Late this month nurseries begin selling bare-root artichokes, asparagus, berries, grapes, kiwifruit, horseradish, and rhubarb. Buy and plant early in the month while roots are still fresh. If the soil is too wet to plant, temporarily cover the roots with moistened mulch to keep them from drying out.
- Plant seeds for cabbage, chard, broccoli, cauliflower, and spring lettuce in a cold frame or in the greenhouse.
Lawns
- If rains haven’t come, irrigate lawn once or twice this month.
Spray
- To smother overwintering insect eggs and pest such as aphids and mites, and scale, spray deciduous flowering and fruit trees as well as roses with dormant oil after the leaves have fallen. Make sure the weather will provide 24 hrs. for the spray to dry.
- Apply neem oil or potassium bicarbonate to roses to control black spot, mildew and rust.
-
All fruit and nut trees: Check IPM for safe and effective sprays
- Note: All the effective insecticidal sprays kill bees and other beneficial insects. Do not spray while trees are in bloom.
