plan where each plant should be depending on what is near it, best time to harvest, varieties, etc....I can help with everything, so I figured I would post Sunsets "what to do in the garden in March". I'll post April tomorrow.
Grow camellias Sunset climate zones 4–7: Some of the finest garden camellias are also some of the oldest. Try white ‘Alba Plena’ from 1792, a pink bloomer with white markings from 1831 called ‘Elegans’ (or Chandleri Elegans), the blush pink ‘Magnoliiflora’ from 1886, and an orangey rose-pink type called ‘Kumasaka’ that dates back to 1896.
Plant vegetables Start cool-season veggies: seedlings of broccoli, cabbage, cauliflower, celery, herbs, onion-family members (including chives), and Swiss chard; roots of asparagus and rhubarb; seeds of peas, radishes, and leaf crops such as spinach and Asian greens; and potato tubers.
Sow seeds of warm-season edibles such as cucumbers, eggplant, melons, peppers, squash, and tomatoes now so they’ll be ready to plant out in May.
Divide perennials Zones 4–7: This is the best time to divide summer- and fall-flowering perennials like asters, black-eyed Susan (Rudbeckia hirta), chry-san-themums, purple coneflower (Echinacea purpurea), and Shasta daisies. Zones 1–3: Divide in April. Wait until autumn to divide spring-flowering perennials.
Patrol for slugs Kill European black slugs (these are mostly brown, but sometimes white or black) when you find them, since they love tender seedlings. Don’t kill banana slugs (usually yellow or yellow with black spots, sometimes green or white, up to 10 inches long), since these natives are most interested in mushrooms, dead plants, and leaf litter. Leopard slugs (gray with black spots) are omnivores ― which is bad when they’re eating your lettuce, but good when they’re devouring European slugs.
