How to Treat Trees Affected By Construction Work

Posted on

Do you have trees in your landscape that have been negatively affected by construction work during a home renovation project? Read on and discover some measures that can be taken to restore the health of those trees.

Improving Aeration

The soil in the root zone of the trees may have been compacted when construction vehicles moved over that soil as they ferried construction materials and debris. This compaction can reduce the aeration of the soil. It can also hinder the effective uptake of water and minerals by tree roots. Thus, improving aeration of that compacted soil is of utmost importance if the trees are to recover and thrive. Rent a soil air-excavation device from a landscaping company near you and use that device to pulverise the soil without affecting the root system of the trees.

Healing Damaged Roots

Some of the roots of the trees may have been damaged as construction work was being done. For instance, some roots may have been cut as a trench was being dug to drain water away from a kitchen extension. You can stimulate root growth in the affected area by applying a thick layer of organic mulch around the root zone of the tree. Examples of the organic mulch that you may use include pine needles and wood chips. For younger trees, the tree zone may cover the diameter of the canopy of that tree. Older trees may have roots that spread beyond the canopy of the tree. The mulch will help to retain moisture in the soil. It will also condition that soil by increasing the organic matter in the soil. These benefits will create favourable conditions for the recovery and growth of the trees' root system.

Treating Damaged Bark

The bark of your trees may have been torn or shredded as construction equipment rubbed against the trees. Use a sharp knife to cut away the damaged bark. Be careful as you do this so that you don't damage other living tissues on the tree trunk. You should also cut away any jagged edges from the damaged bark. Jagged edges can provide hiding space for insects and other organisms that may infect the wounded tree. Do not dress the wound as that may promote the development of rot.

Contact tree management professionals for help if the trees have extensive damage, such as weakened branches. Those professionals will assess the condition of your trees and recommend the best course of action to take.
