Trees and Shrubs
Flowers
- 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.
