How to Support newly planted trees

Inspection

We should inspect newly planted trees on a regular basis to ensure that they are being adequately protected. Fences, tree cages, tree shelters and tree cages can be vandalised or damaged naturally so we should inspect them to ensure that no damage has been done that could jeopardize their function.

Fertilizing

Newly planted trees need to be supplied with adequate amounts of the major nutrients nitrogen, potassium and phosphorous. Once planted trees need to develop a sound structural base, so it is advisable to use a phosphorous based fertiliser as phosphorous helps roots to develop.

Watering

We need to ensure that the plant is adequately watered after planting. The surface soil may appear moist but this does not necessarily mean that the lower levels of soil are moist. We must water thoroughly to ensure the soil is moist until the newly transplanted tree is firmly established in its new location. When using a watering can it is important to use a rose so that an even spread of water is produced. It is best to do watering at dusk or dawn in order to avoid water being transpired by wind or sun.

Mulching and Weed Control

Mulching is very effective at getting newly planted trees off to a good start. Mulch helps the ground to retain water and it protects roots from temperature extremes. In addition mulching suppresses weeds which could otherwise compete with the tree for water and nutrients. Organic, such as bark, or inorganic mulches, such as black plastic can be used. Organic mulches should be applied to a depth of 10cm. One must ensure that the mulch does not touch the stem of the plant as such contact may result in disease. Weeds should be removed because they compete for nutrients and water. They also host pests and diseases. Weeds can be controlled by using a mulch as outlined above. Alternatively they can be removed manually or weed killers, that do not adversely affect tree roots, can be applied.

Pruning

Dead, diseased or dying material should be cut away from trees and shrubs. Any branches that are rubbing or crossing should be cut away because this allows air to flow around the crown, facilitating the production of stronger, healthier branches.

Adjustment and Removal of Supports

Ties that hold newly planted trees in place should be adjusted as trees grow. The aim is to hold the tree in place whilst ensuring the growth of the plant is not inhibited in any way. Guys that are attached to newly transplanted semi-mature trees should be loosened in the same way. Once trees are firmly established in their new locations tree supports should be removed.
