January to March: Young or weak growing trees and shrubs, summer blooming shrubs such as roses, rose of Sharon, crape myrtle, and certain spiraeas.
April to May: Spring flowering trees and shrubs such as azaleas, camellias, daphne, forsythia, lilacs, rhododendrons, cherries, plums, deciduous magnolias, and crabapples, after they are finished blooming. Also, needle-leaf and broad-leaf evergreens can be pruned or sheared.
June to August: Overgrown or neglected deciduous flowering or fruit trees and shrubs, suckers and watersprouts, and faded flowers on summer blooming plants such as roses and spiraea. Also, needle-leaf and broad-leaf evergreens can be pruned or sheared.
September to October: Only necessary pruning to prevent limb breakage during winter weather.
November to December: Perennials and shrubs that die back over winter such as hydrangeas, and Confederate Rose hibiscus.
Dead or diseased wood should be pruned out immediately in any season. Sterilize pruning tools with bleach or disinfectant between every cut to prevent spreading the disease.
Steps 5 and 6 may not be needed if the branches are not crowded.
