Priscilla’s Garden To-Do List for July

Installing Blueberry Netting

  • Keep up with summer watering (instructions here)
  • Lift perennials and trailing branches of shrubs to weed
  • Replenish and refresh containers for summer, adding a layer of mulch to help conserve moisture
  • Begin summer pruning of spring blooming ornamental trees and shrubs
  • Prune to open up boxwoods, yews, rhododendrons and all broadleaf evergreens
  • Deadhead spent blooms of peony, iris, hellebore, columbine, delphinium, rose and other late spring bloomers
  • Fertilize peonies and delphiniums after bloom to promote good bud set for next year (delphiniums may rebloom in fall)
  • Clean up decaying bulb foliage after it yellows and scratch in bulb fertilizer
  • Tie up tomatoes and pinch off suckers to control sprawl
  • Harvest lettuce, chard, herbs and greens in the vegetable garden promptly before they go to seed
  • Replace bitter, bolted or wilted crops with beans, summer squash, basil and other heat loving crops
  • Harvest garlic when only 5 sets of green leaves remain on the plant (usually around July 15) and air dry the bulbs
  • Remove strawberry runners, or transplant them to a new bed (and water well)
  • Topdress the asparagus patch with compost and top off its straw mulch
  • Install blueberry netting to protect your crop from birds
  • Stake tall annuals and perennials
  • Mow lawns high (3 1/2″) and less frequently in drought conditions to shade out weed seeds
  • Continue to water lawns seeded this spring and any plant installed within the past two years
  • Make notes about plants to add, transplant or remove from the garden later in the season, as now you can see how much space each plant fills
