3. EVERGREENS, such as boxwood or yew, can be lightly pruned after the new growth fills in to maintain a formal shape.
5. PRUNE weak, green but very fast-growing water sprouts that grow vertically from branches of fruit trees, redbuds, or other ornamental flowering trees.
8. MULCH. Apply 1 to 2 inches of leaf mulch on flower beds and around trees, keeping mulch away from the trunks. Mulch conserves moisture, protects plant roots, suppresses weeds, and regulates soil temperature.
10. WATERING SCHEDULE. Implement a watering schedule for all plants to help prevent drought stress.
11. LOOK for insect damage. Damaging insects can be very active at this time. Call your arborist if you detect trouble.
12. PRECAUTION. Be careful not to wound trees with lawn mowers and trimmers.
14. PRUNE Spring flowering shrubs. Pruning after they flower encourages maximum blossoms for the next year.
15. PLANT TREES. In many areas, June is a good time for planting trees, shrubs, vines and ground cover.
16. THIN FRUIT TREES. Take care of fruit trees now to make sure you get your sweet rewards later in the season. Thin Asian and European pear trees heavily now.
17. ANALYZE YOUR TREES. If it's a "light year" for any of your apple trees, avoid pruning them — but the heavier fruit bearers should be thinned lightly after their unpollinated fruit has dropped. Remove one apple from triple and double clusters to encourage the growth of larger fruit.
18. DESTROY LARVAE. If you find tent caterpillars in tree branches (they're especially fond of crabapple and fruit trees), prune out the limbs and destroy the cocoons.
