Fertilizer trees and shrubs in March. Use a flowering plant food for flowering plants and trees (azaleas, rhododendrons, hydrangeas, cherries and dogwoods) and a tree and shrub food for evergreens and deciduous trees (hollies, boxwoods, yews, maples and oaks).
Prune roses, crape myrtle, panicle hydrangea, althea and other vigorous summer blooming shrubs. This is also the time to prune boxwoods, hollies and yews.
Cherries, peaches, plums and pears all bloom this month.
For all your new plantings, fertilize with a starter plant food at the time of planting. This will encourage root growth and help get the plant off to a vigorous start.
Prevent cedar-apple rust by applying Immunox on apple, hawthorn and other rosaceous host plants.
