Prepare gardens for the cooler temperatures of winter.
Plant winter color annuals such as cyclamen, primrose, pansies, violas, lobelia, snapdragon, petunia, gazania, nasturtium and sweet pea.
Sow seeds for beets, bok choy, bulb and green onions, collards, endive, kale, leaf lettuce, leeks, mustard greens, peas, radishes and spinach.
Plant colorful perennials such as angelita daisy, gaura, hummingbird trumpet sage and Mount Lemmon marigold.
Sow wildflower seeds by mid-month to take advantage of winter rains.
Choose a location that receives full sun in winter.
Continue transplanting desert-adapted trees and shrubs, ground covers, vines, cacti, succulents and grasses.
Transplant culinary herbs such as cilantro, dill, fennel, parsley, marjoram, mint, chives, rosemary, catnip, oregano, society garlic and sorrel.
Also, transplant broccoli, cabbage, cauliflower and chard.
Set out rain lily bulbs now.
Plant them under trees or among rocks.
Adjust automatic irrigation timers to reduce water.
Irrigate citrus trees about every three weeks to a depth of three feet.
Plant requirements for moisture diminish as weather cools and day length shortens. Reducing water helps plants go into dormancy and prepares them to resist freezing.
Do not fertilize roses or tropical landscape plants such as bougainvillea and hibiscus.
Do not fertilize new growth on citrus.
Add small amounts of ammonium nitrate fertilizer to winter vegetables every month.
Move tender potted plants to sunnier locations or in protected spots under porches, eaves or tree canopies.
Don’t water cacti and succulents before frosts.
Place polystyrene cups over the tops of columnar cacti.
Drape small trees with frost cloth; wrap young citrus trunks with burlap.
The first of the winter vegetables will include radishes, spinach, arugula and leaf lettuce. Thin vegetable seedlings and enjoy in salads.
Test citrus to determine ripeness. Tangerines ripen first, followed by navel oranges, tangelos, lemons and limes.
TIP OF THE MONTH
Silver and gray foliage plants can make a striking display in your garden. Many of these light-hued species are drought tolerant and native species, having adapted to extreme climate and soil conditions. The tiny leaf hairs provide protection from long hours of sun and minimal cloud cover by reflecting solar radiation, which slows evaporation and cools leaf surfaces. Their unique color makes them excellent companion plants to contrast with green-leafed varieties. HG
