Planting

Bearded iris Set out rhizomes of bearded iris in cooler summer areas now; in warmer areas, wait until the temperatures have cooled at summer's end to plant.

Two Northern California mail-order sources are Napa Country Iris Garden in Napa (www.napairis.com or 707/255-7880) and Nola's Iris Garden in San Jose (www.walking-p-bar.com or 408/929-6307).

Fall vegetables Sunset climate zones 1 and 2: For fall harvest (except in highest altitudes), plant beets, broccoli, bush beans, cabbage, carrots, cauliflower, green onions, peas, spinach, and turnips.

Widely available reblooming varieties to look for this month include 'Endless Summer', with flowers that are pink in alkaline soil and blue in acid soil, and new 'Endless Summer Blushing Bride', with brilliant white blooms that develop a hint of pink when mature.

Deadhead blooming plants Remove spent flowers from annuals and perennials such as daisies, daylilies, geraniums, marigolds, and penstemon to promote new blooms. Make sure to deadhead the entire flower so you remove the part where the seed forms. Marguerites and low-growing verbenas that produce masses of blooms can be time consuming to deadhead; shear off flowers with clippers instead. …
