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.

Plant Citrus

This is the perfect time to plant young citrus trees. Look for plants in 1 gallon cans to save money, if you can find them. Incorporate plenty of organic compost into the planting hole, watch the planting depth, and water young trees twice a week until the weather cools. No fertilizer until you see new growth.

Prolong Blooming Roses

Feed, water, and mulch around the base of roses. This will keep them blooming well into the fall and protect them from drying out from hot weather still to come. Use 15-30-15 fertilizer to promote bloom rather than foliage growth.

Water Redwood Trees

Keep watering redwoods until the winter rains begin. Redwood trees need additional moisture now because the summer fog season is over. Redwood trees capture fog in their needles and drip onto their shallow root system during the foggy months. Provide water directly to the roots by using soaker hoses. Cover the hoses with a layer of mulch to protect them from the sun.

Plant Winter-Blooming Annuals

Stock, pansies, violas, snapdragons, and calendula are available now for fall planting. Protect new transplants from hot weather by covering them with newspaper tents. Make sure to leave an opening so that trapped air can escape. Water only when the soil feels dry to the touch. Young plants can't take up water quickly enough to prevent wilting. If you water when the soil is moist, you risk damaging the roots.
