Annuals Continue preparing beds Start seed of fast-growing annuals indoors such as Zinnias and Marigolds Sow seeds of hardy perennials outdoors, such as Cornflower and Larkspur Apply pre-emergent herbicide, such as “ Preen ” to reduce spring germinating weeds. Vegetables and Herbs Plant cabbages and onions Direct-seed peas and continue succession plantings for lettuce, radishes and spinach As soil warms, direct-seed beets, carrots, turnips and other cool-season crops. Cut back over-wintered sage and lavender, and direct seed or plant other hardy herbs. Patio and Container Plants As the weather permits, place over-wintered containers and those started indoors outside Fill gaps or replace winter plantings with those for spring and summer Be prepared to protect tender plants from possible late frost. Cover with a fabric material,  not plastic. Tree and Shrubs Apply 2-3 inches of organic mulch around new and established plants Prune young azaleas, rhododendrons, and wisteria just after flowering to encourage compact  growth. Remove dead and misshapen branches. Apply a well-balanced fertilizer, such “ Hollytone ” to evergreens with yellowing leaves Pinch off contorted new growth on pines to remove pine shoot moths. Roses Prune ever-blooming roses Plant container roses anytime until July Apply complete slow-release fertilizer, such as “ Osmocote ” to established roses Begin weekly sprays to control black spot and mildew Remove winter-killed wood from old garden roses but do not shape or thin at this time. Tomatoes Start main season varieties indoors now. There are usually 4-6 weeks of unpredictable  weather left before being transplanted outside Early seedlings sown indoors may need transplanting to individual pots Finish incorporation fertilizer, compost, over-wintered cover crops, or crop residues into the beds. Check and clean last year's cages, trellises, stakes, etc. Perennials and Bulbs Complete soil preparation, division, and planting Weed, water and fertilize with “ Osmocote ” or “ Plant Tone ” as-needed Do not remove foliage from spring flowering bulbs until it has started to dry-out on its own Lawns Sharpen mower blades De-thatch and aerate if not done earlier in spring or previous fall Apply “ Green Power ” or “ Preen for Lawns ” at the recommended rate Over-seed with a variety suitable for your area if not over-seeded last month Keep moist until seeds until seed sprout.
