Southern California Coastal & Inland Valleys
Place potatoes in a four-inch-deep trench dug well with compost, and cover the cut-and-calloused pieces or small whole tubers with more compost to the original soil level. Water lightly, just to settle the soil close to the seed pieces. Too much water in clay soil will rot them.
Last Chance to Plant Bare-Root!
This is the last month to plant bare-root fruit and nut trees, vine berries, grapes, and strawberries so they'll get a good start. Fill planting holes with their original soil. Use organic matter as a 3- or 4-inch thick mulch on top.
Feed Established Fruit Trees
Feed established deciduous fruit trees about three weeks before you expect them to bloom, so they have the nutrition they need to produce strong blooms and foliage.
Plant Bulbs for Spring and Summer Color
Plant bulbs for spring and early summer blooms, including achimenes, agapanthus, amaryllis, tuberous begonias, caladiums, calla lilies, canna lilies, colchicums, dahlias, daffodils, daylilies, gladiolus, bearded and Dutch iris, sternbergias, tigridias, and tuberoses. For continuous spring bloom later this spring, plant a selection of anemones, gladiolus, ranunculus, and tigridias every two weeks through March.
Keep Lawns Mowed
Slow growth doesn't mean mowing isn't needed. The grass will go into shock if more than 25 percent of its new growth is mowed at one time. Keep mower blades sharp -- raggedly-cut grass blades die back and invite diseases.
