Many New England gardeners think spring is the only planting season, but late August is actually one of the best times to add trees and shrubs to your landscape.
Warm soil, cooler nights, and fewer periods of extreme heat create ideal conditions for strong root development before winter arrives.
Cooler Nights Mean Less Stress
As temperatures begin to moderate, newly planted trees and shrubs experience less heat stress while continuing to establish healthy roots.
Warm Soil Encourages Root Growth
Even as top growth slows, roots continue growing well into fall.
This gives plants several weeks to establish before the ground freezes.
Water Consistently
New plantings still require regular watering.
Remember to:
- Water deeply
- Check moisture often
- Mulch around roots
- Avoid shallow daily watering
Mulch Matters
Two to three inches of mulch helps:
- Retain moisture
- Moderate soil temperatures
- Suppress weeds
- Protect developing roots
Get Ready for Fall Planting
August is the perfect time to choose:
- Flowering shrubs
- Evergreens
- Shade trees
- Native plants
- Ornamental trees
Shopping early often means better plant selection.
