In some areas it is necessary to protect young trees from damage caused by rabbits or other animals. Staking helps to anchor the roots while allowing the trunk to flex in the wind, which strengthens it. It is vital to stake larger trees and those planted in exposed situations. When planting, the point where the roots flare out from the trunk should be level with the surrounding soil.ĭo not add organic matter to the planting hole as it decomposes causing the tree to sink. Make the planting hole at least three times the diameter of the root spread of bare rooted plants or the pot if container grown and a depth of 30cm.įork over the base and sides of the hole to break through smeared surfaces and aid drainage, but do not dig over the base because the disturbed soil will settle, resulting in the tree being too deep once planted. Evergreens establish well when planted in autumn or early spring. Trees less than 1.2m tall, called ‘whips’ or ‘maidens’, are much cheaper and establish more quickly and soon catch up with larger specimens planted at the same time.

It is important to choose species suited to local conditions, such as soil type and exposure, and those that will not outgrow the space available. All these trees are native to Great Britain and will provide a good habitat for local wildlife. Towards the bottom of the page you will find a list of trees that are suitable to plant in the school grounds.
