More Lettuce All Season Long

Continue reseeding heat-tolerant leaf lettuce throughout the summer. Then you'll have seedlings to plant into unused spots in the garden as earlier crops are harvested.

Get Herbs Started

Herbs to sow or transplant include anise, basil, borage, burnet, catnip, chervil, chives, cilantro (when you harvest the seeds, it's called coriander), comfrey, dill, fennel, lavender, marjoram, mint, oregano, rosemary, sage, savory, tarragon, and thyme. Many perennial herbs make attractive, drought-tolerant, trouble-free landscape plants. Also try some herbs indoors next to a very brightly-lit window - dwarf green or dark opal basil, chervil, chives, dill, marjoram, oregano, parsley, savory, and thyme.

Clean Up Ground Covers

Plant or prune ground covers, such as ice plant, ivy, potentilla, and wild strawberrry, to clear away dead portions and stimulate new growth. Drought-tolerant choices include coyote bush, creeping coprosma, gazania, Mexican evening primrose, rosemary, and verbena.

Dry-Area Blooming Shrubs

Water-conserving blooming shrubs for dry spots include crape myrtle, oleander, rosemary, and wild or California lilac.

Get Weeds Now

Continue pulling weeds before they form seed heads or scatter their seeds, and you'll have fewer weed problems later. Weeding the day after watering will ease the chore, as entire root systems will come out more readily when the soil is moist. If you leave pulled weeds in garden pathways for dry mulch, be sure to leave them with their roots up so they don't re-root themselves. But don't leave weeds that have already developed their seed heads--some seeds may mature and germinate next year. And you certainly don't want this kind of recycling!
