1. Water trees and shrubs deeply if natural rainfall is less than one inch per week. Watering the soil and not the foliage reduces leaf spot diseases.
  2. Replenish mulch under trees and shrubs. Mulch should extend to the drip line (end of branches), or at least cover a four to six foot diameter circle.
  3. Mushroom compost is an excellent top dressing for flower beds. It can be worked into the soil as it decomposes.
  4. Prune late spring flowering shrubs and hedges now.
  5. Pull weeds before they go to seed.
  6. Plant summer flowering bulbs and annuals. Annuals are developing roots. Fertilize and keep well watered.
  7. Monitor container plants, especially those in clay pots, daily for watering needs.
  8. Pinch garden mums and asters once a month, until July 15th, for bushier growth.
  9. Remove faded blossoms from flowering annuals, perennials and roses to encourage more blooms.
  10. Fertilize roses with a 10-10-10 slow release fertilizer after first bloom.
  11. Check bird houses for unwanted tenants and fill birdbath regularly.
