Change the Watering Routine
Water early in the day or late afternoon on hot days to prevent sun scald on tender leaves. Water applied during the heat of the day is lost to evaporation and doesn't reach the roots.
Plant Cool-Season Annuals
Plant cilantro, cabbage, broccoli, and cauliflower now for fall harvest. Cool-season plants respond to the diminishing length of the daylight and to cool nighttime temperatures.
This is the perfect time to plant young citrus trees. If you have ever wondered what all the hoopla about Meyer lemons is all about, now is the time to find out. Incorporate plenty of organic compost into the planting hole, plant so that the bud union is well above the ground to avoid rot, and water young trees twice a week until the weather cools. No fertilizer until you begin to see new growth.
Root Herb Cuttings
Herbs such as basil, marjoram, and oregano are going gangbusters right now. If you have more herbs than you can use, share them with friends by either dividing the plants or making cuttings. Basil roots easily in water, as does marjoram and oregano. Rosemary is more difficult to start and should be propagated by tip cuttings. Take several to ensure viability.
Pick Up Fallen Fruit
Remove any fruit that has dropped from apricots, plums, peaches, and nectarines to prevent insect damage next year. Insects lay their eggs in fallen fruit, then winter over in the soil under the trees. This simple step will prevent a majority of fruit tree problems.
