The fickle weather of March and April makes it impossible to set dates and schedules for planting, but with spring just around the corner, it’s time to get serious and get the garden ready; so proceed with caution. March is the month when many of the beautiful spring flowering perennials begin to flower and brighten our days, making us anxious for spring.
For shrubs and trees, it is still possible to do dormant sprays on fruit trees. Dilute your spray to half the full rate and spray on days when the temperature is above 40 degrees Fahrenheit. If you see buds breaking dormancy, hold off with the dormant sprays and use another option.
March and early April is a good time to transplant or prune shrubs and trees, if buds haven’t swelled or broken open.
Shrubs and trees should be fertilized, if this wasn't done in February. Use an acid-type rhododendron fertilizer to feed evergreens, conifers, broad-leaf evergreens, Rhododendrons, azaleas and camellias. An all-purpose fertilizer can be used to feed roses and other deciduous trees and shrubs.
Divide and transplant summer blooming perennials and fertilize established ones as soon as new growth appears.
Severe pruning of roses results in nicer long-stemmed flowers and more compact bushes. Begin to feed and spray roses for black spot now!!
Winter jasmine can be pruned after flowering. As for honeysuckle cut the plant back to 3 feet.
Begin to plant summer-blooming annuals and summer vegetables, such as tomatoes and lettuce, indoors. Seedlings started in February can be transplanted into peat pots.
Primroses and pansies can also be planted now. It is also safe to plant tender bulbs and tubers such as gladiola, lilies and dahlias now. Continue planting additional bulbs every two weeks until mid June to ensure a continuous source of bloom throughout the summer.
