Beat the burn: Planting trees and shrubs in July

Just because it's the middle of summer doesn't mean you've missed your chance to plant trees and shrubs.

University of Missouri Extension horticulturist David Trinklein says many trees and shrubs can still be planted successfully in July, especially those that are container-grown or sold balled and burlapped. With proper care, these plants can become established even during the warmer months.

Bare-root trees and shrubs are the exception. Trinklein says they should be planted during the dormant season because they lose much of their root system when dug, making it difficult for them to survive summer heat.

When planting, dig a hole that is wide rather than deep. Tree roots naturally spread outward near the soil's surface, so a broad planting area gives them room to grow. Mixing organic matter into the soil can also help young roots become established.

Trinklein recommends planting trees at the same depth they were growing in the nursery, or even slightly higher to allow for settling. During hot weather, new trees need deep, slow watering at the root zone to help them develop strong roots. A layer of mulch helps keep the soil cool and reduces how often watering is needed.

If temperatures are especially high, misting the leaves or providing temporary shade can reduce stress while the plant becomes established.

A little pruning at planting time is also a good idea. Removing damaged or poorly placed branches helps encourage healthy growth and gives the tree or shrub a better shape as it matures.

With the right planting methods and regular watering, Trinklein says summer can still be a successful time to add trees and shrubs to the landscape.
