JUNE - AUGUST CALENDAR
Oak Leaf Hydrangea brightens up shady spots.
Trees and Shrubs
• Continue pruning blooming shrubs as soon as they finish blooming.
• Deadhead spring-blooming shrubs, to focus the plant's energy toward strong growth and next year's blooms.
• Trim boxwood while the growth is still soft and easy to shape.
• Watch for black spot and powdery mildew on roses and other plants – apply fungicide (Ortho Funginex) and remove (and destroy – don't compost) any diseased foliage.
• Add extra mulch to shallow-rooted shrubs (like native plants, azaleas, camellias, and rhododendrons), to help them hold moisture.
• Remove aphids with a blast of water from the hose. If that doesn’t work Safer Insecticidal Soap should do the trick.
• Reduce (or stop) fertilizing as the temperature heats up.
• Keep plantings and lawn well-watered.
• Lightly shear conifers (junipers, cypress, etc.) but don't cut back to bare wood.
• Keep adding to compost pile and turn weekly.
Raise your mower blade during summer.
Lawns
• Raise the blade on your lawn mower for summer. Cool-season grasses should be mowed at 3”-4”.
• Mow regularly, especially if you’re mulching the clippings. Rake clumps and add to compost.
• Control existing w**ds with a post-emergent herbicide (W**d B Gone or similar product), or by pulling or digging. Removing w**ds before they bloom and disperse seeds helps reduce next year’s crop.
• Reduce fertilizer on cool-season lawns, since they go partially dormant during the hottest part of the summer.
• Apply moss killer before temperatures are regularly above 65° F, especially in shady areas (Scott’s MossX moss control)
• Make sure your lawn gets one inch of water per week. If you irrigate, water deeply to encourage deeper roots.
