Plant Cool-Season Flowers
Sow seeds or set out transplants of baby's breath, bachelor's button, bells of Ireland, dianthus, black-eyed Susan, calendula, geranium, hollyhock, Johnny-jump-up, larkspur, nasturtium, pansy, Iceland and Shirley poppy, purple coneflower, snapdragon, stock, and sweet pea.
Water Citrus Carefully
A healthy crop depends on consistent moisture as fruit develops. Irrigate mature citrus trees at this time of year about every three weeks to a depth of three feet.
Finish planting bulbs for spring bloom. Phosphorus is a nutrient that promotes bloom, but it does not move readily through the soil. Thus, mix a phosphorus fertilizer into the bottom of the planting hole where it will be available for roots to take up.
Buy Tomato Seeds
Before the holiday whirl commands all of your attention, purchase tomato seeds so they will be ready and waiting for you to sow indoors in time for transplanting out from mid-February to mid-March. Good performers in the low desert have small to medium fruits that mature before the intense heat hits. Big beefsteaks generally don't perform well and crack in the heat.
Monitor for Cabbage Loopers
Cool temperatures and cool-season veggies typically add up to cabbage loopers. Watch for their ragged chewing marks on the leaves of broccoli, cabbage, cauliflower, kale, and other greens. Handpicking is an easy control method.
