Indoors

  • Houseplants will need more water and fertilizer during summer growing period.

General landscape

  • Prune spring-flowering shrubs within a month after blooms fade.
  • Supplement water as needed. Most newly planted stock needs an inch of water every week or 10 days. Established trees, shrubs and perennials can go several weeks without supplemental watering.
  • Remove faded blooms from peony, iris, delphiniums and other spring perennials.
  • Container-grown stock, including shrubs, trees, perennials and annuals, can be planted any time.
  • Continue planting gladiolus for successive blooms.

Vegetables and fruits

  • Discontinue harvest of asparagus and rhubarb in mid-June to allow foliage to develop and store food reserves for next year. Fertilize. Water when dry.
  • Blanch (exclude from light) cauliflower when heads are 2-inches in diameter. Tie leaves up over the developing heads.

  • Harvest spring plantings of broccoli, cabbage and peas.
  • Plan your Halloween pumpkin. Determine the days to harvest for particular cultivar and count backward to find the proper planting date.
  • Remove cold-season plants, such as radish, spinach and lettuce, as they bolt or form seed stalks.
  • Every week or 10 days, continue planting carrots, beans and sweet corn for successive harvests.
  • Do not be alarmed by June drop of tree fruit. It is a natural thinning process. If needed, help nature by thinning fruit to 6- to 8-inches apart and propping heavy branches.
