July To Do

JULY Gardening To-Do List


Zone 3

  • Now’s the time to start seeds of cool-season vegetables for fall growing
  • Rogue out (remove) virus-infected plants from the garden and control leaf-hopping insects to prevent virus spread
  • By pruning off faded blooms from annuals, you can prevent seed formation and coax additional flowers
  • Mulch flowerbeds with dried grass clipping or compost to maintain moisture and reduce weeds
  • Save maintenance and water by allowing perennial rye and Kentucky blue grass lawns to go dormant during the summer
  • Raspberries are ripe when they pull readily from the central core
  • Prune water sprouts (upright, vigorous shoots) from apple trees
  • Avoid deep cultivation around shallow rooted trees and shrubs such as evergreens
  • Add a water-soluble fertilizer to hanging baskets and patio pots every 2 weeks to keep plants blooming their best
  • Cut flowers for drying at their prime or when just opening

Zone 4

  • Add one last planting of gladioli bulbs for flowers into fall
  • Harvest veggies as soon as they’re ripe to encourage further production
  • Avoid the sight of a weed-infested garden: weed first before you leave on vacation
  • Harvest sweet corn when silks are brown and punctured kernels produce a milky juice
  • Prevent blossom-end rot on tomatoes by providing plants with at least an inch of water each week
  • Let melons ripen on the vine — this is where they will develop their best flavor
  • Start fall garden transplants from seed
  • Petunias, coleus and other summer annuals might be leggy by now
  • Pinch them back just above a leaf to encourage bushy growth and more flowers
  • Leave faded flowers on those plants that form ornamental seed heads, pods, or berries
  • Provide water in a shallow pan or birdbath for your feathered and fluttering friends

Zone 5

  • Remove annuals with stunted or unusual color; these are usually virus infected and the disease can spread to neighboring healthy plants
  • To control disease on fruit trees, maintain a summer spray schedule
  • Clean hummingbird feeders filled with nectar solution regularly to ward off mold and bacteria
  • Consider drip irrigation and/or soaker hoses for watering in the flowerbed and vegetable garden
  • Bats help control mosquitoes; attract these friendly mammals with bat houses
  • Muskmelons and cantaloupes are ready for picking when the stem “slips” easily from the fruit with gentle pressure
  • Harvest veggies as soon as they’re ripe to encourage additional production
  • Sharp mower blades prevent leaf blade damage and lawn stress
  • Prevent diseases on susceptible rose varieties: apply fungicide every 7-10 days
  • Lanky annuals need your help! Pinch them back now to encourage bushy growth and more flowers
