April Garden by the Month Ornamentals

Trees and Shrubs
  • Newly planted trees require regular watering through their first summer. Apply 2-3 gallons per inch of trunk diameter to the root ball at least once a week if it does not rain.
  • Mulch trees and shrubs to help reduce summer weeds. Apply a 3-4” layer out to the drip line but do not pile against trunks. Too much mulch (over 4”) can repel water.

Flowers
  • Wait until mid month to set out summer annuals and summer blooming bulbs.
  • Newly planted flowers will benefit from liquid fertilization the first few weeks, in addition to slow release fertilizer applied at planting time.
  • Aphids are a common spring pest on many flowers. Wait a few weeks before treating to see if ladybugs move in to control them.
