Southern California Coastal & Inland Valleys
Sow or transplant lima and snap beans, beets, carrots, celeriac, celery, chard, corn, cucumbers, eggplants, oak leaf and other heat-tolerant and bolt-resistant lettuces, melons, okra, peppers, sweet potatoes, pumpkins, radishes, New Zealand spinach, summer and winter squash, and tomatoes.
Plant the Last Batch of Corn
Get the last of the corn planted this month, as later plantings will probably have smut problems (those big, grey and black puffs of fungus in place of kernels) when harvested in September. Or you may choose to inoculate your corn with the fungus; it's considered a delicacy in Southwestern and Mexican cuisine.
Learn the Needs of Different Herbs
Lavender, marjoram, rosemary, sage, savory, and thyme do fine in hot sun and poor but well-drained soil with minimal fertilizer. On the other hand, basil, chives, coriander (cilantro), and parsley prefer richer soil with more frequent watering.
Water Citrus and Avocado
Keep citrus and avocados well-watered (deeply every two or three weeks) and give them a 3-inch-thick layer of mulch to maintain uniformly cool temperatures. They are more tender than other fruit trees and cannot withstand the stress of alternating moisture and dryness. Citrus roots grow beyond the tree's dripline, so give it a larger basin area.
Pinch for More Flowers
Pinch back tips and faded blooms from alyssum, tuberous begonias, carnations, chrysanthemums, dianthus, delphiniums, fuchsias, geraniums, hydrangeas, lobelias, marguerites, and penstemons to encourage bushier growth and more flowers.
