Southern California Coastal & Inland Valleys
If you planted asparagus, artichokes, or rhubarb this past fall, winter or spring, don't harvest this year. Let the plant use all its energy to develop a good root system and strong first shoots, instead of expending its energy having to send up more shoots to replace harvested ones. Next year you can begin harvesting.
Fertilize strawberries with a balanced fertilizer after each fruit-bearing period for continued strong growth and fruit set. I like using a seaweed and fish emulsion solution because it offers many micronutrients. Avoid applying fresh manure, as strawberries are not tolerant of salts, and fresh manure contains a relatively high level.
Trellises provide support for greater fruit production over longer periods. Erect plants have more leaf area exposed to sunlight, which increases growth and production. They also receive more air circulation, reducing fruit rot and ground-insect attack. Vines spreading on a trellis can provide shade for a porch, patio, or wall. Crops grown on a trellis are easier to pick and less likely to get attacked by snails and slugs.
Paint Tree Trunks
Paint tree trunks with light-colored indoor latex paint to prevent sunburn damage. This is especially important for young trees with tender bark. Use an inexpensive brand, or thin an expensive brand by mixing one-half paint with one-half water. Paint the lower third of the tree, concentrating on the south-facing side.
Prune azalea, carnation, chrysanthemum, fuchsia, geranium, impatiens, lavender, marguerite, marigold, petunia, rhododendron, rosemary, sedum, and zinnia, gently shaping the plants to encourage them to send out more side branches. Use the cuttings to root new plants.
