As August arrives, many gardeners begin thinking the growing season is winding down. In reality, it’s one of the best times to plant trees and shrubs in Connecticut. Warm soil, cooler nights, and shorter days create excellent conditions for roots to establish before winter, giving new plants a healthy head start for next spring.
If you’re planning to update your landscape, August is the perfect month to get started.
Cooler Nights Reduce Plant Stress
While daytime temperatures can still be warm, cooler evenings help reduce stress on newly planted trees and shrubs.
Instead of using energy to cope with intense summer heat, plants can focus on developing healthy root systems.
Warm Soil Encourages Root Growth
The soil remains warm throughout August, encouraging roots to continue growing long after top growth begins to slow.
This allows plants to become established before winter dormancy and prepares them for vigorous spring growth.
Watering Is Still Important
Newly planted trees and shrubs need consistent moisture while they establish.
For best results:
- Water deeply once or twice a week
- Check soil moisture regularly
- Water at the base of the plant
- Avoid frequent shallow watering
Deep watering encourages stronger, deeper root systems.
Mulch Helps Plants Thrive
Adding two to three inches of mulch around new plantings offers several benefits:
- Conserves soil moisture
- Keeps roots cooler
- Suppresses weeds
- Protects developing root systems
Be sure to keep mulch a few inches away from the trunk or stems to prevent rot.
Great Plants to Add This Month
August is an excellent time to begin selecting:
- Flowering shrubs
- Evergreen shrubs
- Shade trees
- Ornamental trees
- Native plants
Shopping early often provides the best selection before the busy fall planting season begins.
Plan Ahead for Fall Success
Planting in August gives trees and shrubs extra time to establish before cold weather arrives. With proper watering and care, they’ll be well positioned to thrive next spring with healthy growth and beautiful blooms.
Frequently Asked Questions
Is August too hot to plant trees and shrubs?
Not at all. With regular watering, August is one of the best months to plant because warm soil encourages rapid root development.
Will roots continue growing after planting?
Yes. Roots continue growing well into fall while the soil remains warm, even after top growth slows.
Should I mulch around newly planted trees?
Absolutely. Mulch helps retain moisture, regulate soil temperature, and protect developing roots.
How often should I water new shrubs?
Water deeply once or twice a week, depending on rainfall and soil conditions. Check the soil regularly to avoid overwatering.
Is fall planting better than spring?
Both seasons are excellent, but planting in late summer and early fall gives roots several weeks to establish before winter.
