Fertilize roses, annual flowers and berries with slow-release fertilizer when spring growth begins. Pull weeds. Fertilize citrus and deciduous fruit trees. Check roses for aphids; control with a strong spray of water or insecticidal soap. Spray apricots with a fungicide as flowers open to prevent brown rot. Cut back, divide and fertilize herbs. Prepare beds for planting by spading in compost. Prune and fertilize spring-flowering shrubs and trees after bloom. Fertilize cool-season lawn grasses (bent, blue, rye, and fescue). Fertilize camellias at the end of bloom. Try using composted or well-aged manure. Check irrigation system and perform maintenance.
