Fertilize permanent plantings. Most ornamental trees, bushes, lawns and ground covers respond well to fertilizer at this time. In good years abundant spring rains green up the hillsides and bring out wildflowers, gardeners don't have to water as much, and salts are leached out of our soils. But heavy rains also wash soluble nutrients, especially nitrogen, down to lower levels, sometimes out of reach of roots. So fertilize the basic landscape with a complete granulated fertilizer high in nitrogen like Master Nursery Multi-Purpose Fertilizer. If you have a straggly ground cover that's never quite covered the ground, a sprinkling of granulated fertilizer in early March will do wonders. Water it in thoroughly or apply it when the weatherman says we're going to have rain.
This doesn't mean you should simply fertilize everything in sight. Many plants fall into the broad category of specialty plants because they require special handling. Some specialty plants, including cacti, succulents, and native plants, have little or no need for fertilizer. Others, such as camellias, azaleas, begonias, fuchsias, ferns, orchids, epiphyllums, roses, fruit trees, and vegetables have unique requirements. Follow the directions for them in this and other monthly chapters.
Plant new permanent specimens. March is one of the two best times of year to plant almost anything we grow in the permanent landscape, such as trees, shrubs, vines, and ground covers. The other is October. Planting in fall is traditionally considered to be just a bit better than planting in spring, but after a year or two you'll never know the difference. Now through mid-June is the time to look your garden over, see its strengths and weaknesses, replace troublemakers you don't like, and add permanent specimens where needed. Choose drought-tolerant plants over heavy water users. Be sure to group plants according to their needs for water, for sun or shade, and for soil type. Before purchasing any plant, research its requirements and growth habit.
