SOLUTIONS FOR STRESSED TREES

Many trees can tolerate the poorest conditions in which to grow coping with soils low in nutrients and organic material but occasionally a mature tree will start to show signs of stress. This can often follow disruption to roots, by compaction or other physical damage or stress for example on development sites or simply through lack of water. And as with all plants the answer truly lies in the soil. If the conditions for growth are optimised even mature specimen trees can recover.

CASE STUDY:

Problem: Beech tree in a rear garden in Cardiff , which was showing clear signs of stress, with depleted foliage of a very small size and the death of branch growth tips. The soil was observed as heavy, poorly drained clay and the area immediately beneath the tree was lawn.

Solution: Improve drainage and increase availability of nutrients to tree.

Method: Inject surrounding soil with compressed air to open up soil and allow free drainage
Inoculate soil beneath tree canopy with Mycorrhizal soil drench, (a solution of beneficial fungal spores that colonize the soil and live in symbiosis with fibrous root hairs increasing the plants ability to assimilate soil nutrients).
Mulch the soil with partly composted wood chip and leaf matter to encourage the development of mycorrhizal associations.

Within 2 years this tree begun to show clear signs of recovery with larger leaf size.	Dense fibrous roots.
A full dense crown.	Mulch beneath canopy.
