Gardening Tips for July
Despite good cultural practices, pests and diseases at times may appear. Chemical control should be used only after all other methods have failed.
- Fertilize roses for the last time in mid-July so that new growth can harden off before frosts.
- Cutting late-blooming perennials such sedum, aster, chrysantemum, and boltonia back by one-third around July 4 will promote bushier growth. Pinching back new growth will keep plants compact.
- Systemic grub control should be applied to the lawn by July 15th to be effective when grubs hatch in early August.
- Cucumbers are heavy drinkers and feeders. Keep the soil evenly moist during hot spells to avoid bitter fruit and side-dress plants with 1 tablespoon of 10-10-10 fertilizer.
- Inspect garden plants regularly for insect and disease problems. Monitoring, good sanitation practices, insecticidal soaps and insect traps are alternatives to pesticides.
- Summer blooming shrubs should be pruned after they have finished flowering. Do not prune azaleas and rhododendrons after the 2nd week of July as they are forming buds for next year's blooms.
- Put netting on fruit trees and bushes a few weeks before the fruit begins to ripen to protect it from birds and squirrels.
- Raise the mower height to 3” in hot weather and mulch to help conserve water.
- Pinch back herbs to stop flowering and encourage branching. Pick herbs early in the day when they are well-hydrated.
- Leaky garden hoses and fittings can waste water. Check hoses while they are under full pressure and make repairs.
