MARCH To Do’s
NOTE: The average last freeze in DFW is around March 15 – be prepared to protect tender plants.
Plant new trees & shrubs so they establish before summer temperatures. Take advantage of great spring selections. Don’t forget your root stimulator.
Plant cool-season annuals (petunias, alyssum, etc). Warm-season annuals should wait till end of month or early April.
Fertilize flowering annuals monthly … they are heavy feeders.
Fertilize landscape plants - trees, shrubs, perennials, groundcovers, etc. (An inexpensive soil test can provide direction on specific fertilizer formulation.)
MULCH, MULCH, MULCH. We recommend shredded wood mulch.
Apply pre-emergent herbicide early in month according to label instructions. We do NOT recommend “weed-n-feed” products.
Watch new growth on roses for possible Rose Rosette disease. Don’t wait to take corrective action.
Watch out for aphids on tender new growth. They are easy to control if you stay ahead of them.
Prune trees and shrubs as soon as spring growth begins, highlighting damage to be removed. If you must prune oaks (best not to) use pruning paint to prevent Oak Wilt infection.
