WHEN AND WHAT DO YOU PRUNE ON MARCH?
"Rejuvenation" pruning of overgrown broadleaf evergreens should be done the earliest part of this month.
Cut well-established plants back to within 12=18 inches of the ground. Fertilize and water. This can be done to azalea (after bloom), camellia, euonymus, evergreen magnolia, gardenia, hollies, ligustrum, nandina, photinia, pyracantha, and other broadleaf evergreens. Check with office on other plants because they do not tolerate drastic pruning. Drastic pruning now will eliminate spring flowering.
