Tasks
- Water citrus trees well now to produce a good crop next year.
- Check and improve drainage around plants in low areas.
- Monitor rainfall and adjust water accordingly to keep soil moist for new plantings.
Pruning
- Cut back chrysanthemums to 6 inches.
- Prune back spent wisteria canes.
- Do not apply any treatments to pruning cuts or other plant wounds because these materials are ineffective and often detrimental.
Fertilizing
- Fertilize cool-season annuals, perennials and vegetables with a light, high-nitrogen or organic fertilizer.
Planting
- Bare-root planting season begins this month. Consider the hardiness of the rootstock when selecting bare-root fruit trees.
- Citrus, avocado, and other frost-tender plants should be planted in spring after the danger of frost has passed.
- Fruits and vegetables: asparagus (transplant), onions, parsley.
- Annuals: toadflax (Linaria maroccana), stock (Matthiola incana).

- Bulbs, corms, tubers: paperwhite (Narcissus).
- Trees, shrubs, vines: holly (Ilex), Koreanspice (Viburnum carlesii).
- Fruits and vegetables: Brussels sprouts, citrus, sweet potatoes.
Things to ponder
- Use trimmings of magnolias, juniper, pine and redwoods for holiday greens. Deodar cedar, spruce and western hemlock lose needles quickly.

Tasks
- Monitor ground moisture, especially in beds and under eaves and patios.

Fertilizing
- Feed cool weather plants and vegetables.
Planting

Things to ponder
- Enjoy the quiet of the winter garden.
- At the end of the month, apply dormant oil spray to deciduous fruit with copper fungicides, to control shot hole disease on twigs.
- Avoid overhead irrigation if frost is expected.
Historic frost dates
- Zone 8: November 15 through March 15
- Zone 9: December 15 through February 15
- Prepared by: Terry Lewis
Tasks
- The tuberous roots of sweet potatoes will be ruined if the foliage is damaged by frost. Harvest before freezing temperatures kill the vines.
- Use fall leaves as mulch.
- This is the month to stimulate flower bud formation in your Christmas cactus by placing it in darkness for 12 to 14 hours each day when the temperature is 50° to 55° at night.
Pruning
- “Pre?prune” roses by aggressively deadheading spent blooms and removing leaves from canes to nudge plants into dormancy.
- Prune shrubs and trees to shape, except for spring-flowering varieties.
- Thin black pine candles.
Fertilizing
- For even application of nutrients, use time?release fertilizer formulations on cool season vegetables.
Planting
- As outdoor garden activity slows, use the time to transfer some design ideas to paper.
- Fruits and vegetables: cabbage, garlic.
- Trees, shrubs, vines: almond, apple, apricot.
- Annuals: snapdragon (Antirrhinum), calendula, Baja fairy duster (Calliandra californica), Leucanthemum paludosum, Iceland Poppy (Papaver nudicaule).
Enjoy now
- Annuals and perennials: snapdragon (Antirrhinum), calendula.
- Bulbs, corms, tubers: paperwhite (Narcissus).
- Trees, shrubs, vines: abelia.
- Fruits and vegetables: apples, broccoli, cabbage, limes.
- Fall color: aster, Maidenhair tree (Ginkgo biloba).
Things to ponder
- Feed the birds, including resident hummingbirds (and remember to clean your feeders regularly).
- Repair shops are busiest in spring. Now is a good time to have repairs made to power tools and to have your lawn mower serviced.
- Historically, Nov. 15 is the first frost date for Zone 8 and Dec. 15 for Zone 9, but frost may occur earlier.
- Move or cover tender plants. Plastic is not recommended.
Drought tip
- Clean rain gutters and use downspout extensions to direct rain runoff back into the landscape, rather than into the street and storm drains.
- Prepared by: Terry Lewis
Tasks
- Stake newly planted trees in windy areas.
- Clean up debris to eliminate hiding places for pests (if necessary). Or consider leaving fallen leaves and debris where they are, as many beneficial insects lay their eggs in the leaf litter – it also serves as a natural mulch.
- Irrigate citrus trees at night if frost is expected. Damage to citrus varies with variety and fruit ripeness.
- Continue to irrigate if weather remains dry.
Pruning
- Do not top or prune trees severely in an attempt to avoid raking leaves! Extreme pruning will disfigure trees and shorten their lives.
- Discard diseased wood.
- Leaf fall is the time to start pruning - except for apricot, oleander and olive trees, which should have been pruned in August.
Fertilizing
- Add bulb fertilizer to planting holes before planting bulbs.
Planting
- Fall planting ends this month. The soil will cool rapidly, which will slow root growth.
- If you wish to transplant trees in the fall, it is best to wait until December or January when deciduous and evergreen trees are dormant.
- Perennials: dianthus, euphorbia, kalanchoe, red hot poker (Kniphofia).
- Bulbs, corms, tubers: Snowdrop (Galanthus), snowflake (Leucojum), tulip (Tulipa), Watsonia.

- Fall color: Chinese Pistache (Pistacia chinensis), Heavenly Bamboo (Nandina domestica).
Things to ponder
- Calendula petals (fresh or dried) can be used as a substitute for saffron to color rice or flavor soups and stews.
Drought tip
- Landscape watering in many areas is now restricted to one day per week. Check your city's policy for its winter irrigation schedule.
- Prepared by: Terry Lewis
Tasks
- Cut warm-season grasses short and over-seed with cool season grasses – annual or perennial rye or fine fescue. Better yet – let them go dormant to save water and mowing.
- Check and improve drainage around plants in low areas.
- Add fallen leaves, chipped trimmings and garden debris to compost.
- Remember that plants in containers or beds under covered areas may not receive adequate water from rainfall and may require supplemental irrigation in fall and winter.
- Use organic mulch around permanent plants and add organic matter to the soil to prepare beds for spring planting.
Pruning
- Dispose of diseased wood by discarding in the trash.
Fertilizing
- Feed cool-weather plants and vegetables.
- Add bulb fertilizer to planting holes before planting bulbs.
Planting
