Gardening Tips for November
by Thea Fiskin, UC Master Gardener

Finish autumn's chores and prepare the garden for our first frost. Yes, even though fall has been exceedingly warm, Mother Nature has a way of surprising us. Historically our first frost hits in the middle of November. Another reason to expedite clean up is the holiday season. Once that starts we know we won't have time for any garden chores, except for raking leaves.

GARDEN CHORES
Put fallen leaves to good use. First rake into piles, then run over them with the lawn mower to chop, reduce volume, and gather them in the mower's bag. Afterwards add to the compost pile, bury in the veggie garden, spread in flower beds, or store in dark garbage bags. Leaves break down in no time to make a wonderful amendment that enriches garden soil.

Prune dense trees such as the California pepper and Chinese evergreen elm before winter storms arrive. Selectively remove entire branches to allow airflow through the tree canopy and prevent wind from blowing over top heavy trees. PLEASE DON'T stub branches back so trees end up looking like hat racks! Large trees should be pruned by a certified arborist.

Wrap trunks of frost susceptible plants, such as young palms and citrus with heavy paper or burlap, not plastic. Do not fertilize citrus and other frost tender plants, since new growth becomes subject to frost burn.

Wish for rain! Until it arrives keep sprinkler timers on.

Weed prevention: If winter weeds are popping up now, remove them while young before new seeds form. If weeds are a big problem in large flowerbeds or lawns, then apply a preemergence herbicide to prevent annual weed germination. Discourage weeds by mulching flowerbeds, shrubs and trees with a thick layer of mulch or leaves. If using preemergence herbicides, spray first then add a layer of mulch.

Critter control: Now that nights are cooler slugs and snails are lurking about. Hand-pick or use snail bait to control. If you've got pets or kids that gobble up anything and everything, then try iron sulfate baits instead of the poisonous metaldehyde baits. These break down into fertilizer and can be used on any ornamental or vegetable plant right up to picking with no worry for harm.

Perennials: Cut back chrysanthemums after bloom. Leave stems approximately 6" long on big bushes. Old clumps can be lifted and divided, just discard the woody center and replant. Potted plants from stores can also be cut back and planted in the garden. Come spring they will be covered with new foliage.

Dormant sprays: If peach or nectarine trees had curled or puckered leaves this summer, then take preventative measures now against the fungal disease called "peach leaf curl" for next spring. Rake leaves when they fall, remove any fruit mummies, and discard both rather than put them in the compost pile. Spray trunk, branches and ground underneath tree with a copper-based fungicide or a Bordeaux mixture (slurry made of hydrated lime and copper sulfate) or a synthetic fungicide.

WHAT TO PLANT
Add winter interest to your garden with plants that produce berries. One plant may be all that is needed to spark interest in a dreary corner. Try cotoneaster, holly, pyracantha, or toyon.

Winter color - Plant calendulas, delphinium, dianthus, foxgloves, Iceland poppies, ornamental kale, pansies, primroses, snapdragons and stock. Or spread wildflower seeds, like bachelor buttons, California poppies, clarkia, gypsophila, and larkspur. Scatter seeds in prepared soil, rake lightly, and water often to keep seeds moist until they germinate.

Bulbs - You still have all month to plant bulbs. Remember only hyacinth and tulip bulbs need to be chilled for six to eight weeks in the refrigerator prior to planting.

Perennials - Sasanqua camellias (these can take full sun) are in bloom now through early winter, while Japonica camellias (these need shade) bloom in winter and early spring. Choose your Sasanquas while in bloom and plant now.

Trees - Shop for trees with colorful fall foliage in nurseries. Select Chinese pistache, crape myrtle, Japanese maples, redbud, red oak, and ginkgo trees. Ask the nursery for advice on new selections and varieties for these old standbys.

Vegetables - Winter transplants available in nurseries are artichokes, bok-choi, broccoli, cabbage, cauliflower, lettuce and Swiss chard. Sow seed of beets, carrots, lettuce, peas and radishes.
Take time to enjoy the fall colors and celebrate the end of the harvest season with a Happy Thanksgiving.
