Choosing the Right Site

Once you have considered the general climate of your garden, you will then need to think about the specific position in which to plant your tree. The microclimate of your garden may vary considerably from one location to another, and you must make sure that the site you eventually choose provides the right amount of shelter and light. Trees species will vary in their requirements; for example, many large-leaved trees will not grow well in exposed sites where their leaves would be subjected to strong winds and high light levels. They would much prefer a sheltered, partially shaded position.

Trees planted in coastal gardens should be planted in a site sheltered from salt-laden winds and sea spray, as otherwise their growth buds may become damaged and their foliage scorched. However, as can be seen from the tree planting guide, there are a number of species, such as hawthorn (Crataegus monogyna), that will tolerate exposed coastal conditions. These species may be planted to provide protection to other plants from the harsh winds.

In general, try not to plant trees too close to buildings or walls; not only will the trees suffer from reduced levels of light and moisture, but their roots may damage foundations of buildings and drains as they develop. However, you may plant tender species near a warm wall, as the heat retained in the wall will benefit the tree, allowing it to be grown in an area where it would not survive in open conditions. Tender trees may also benefit from being planted half-way down a slope; this position is usually warmer and more sheltered than positions at either the top or the bottom.
