Trees for dry & sunny sites

This snippet has been extracted from “Tree for the Yard and Garden” by “John Cushnie”. Trees for dry & sunny sites are numerous in numbers which are well described & discussed at “Tree Removal in Hayward CA“.

Most trees, by their nature, grow well in shade.  There are, however, some trees that tolerate full sun and these are particularly useful when designing for small sunny gardens.  You need to be aware that gravelly soils, without humus, are free draining and, when coupled with a summer drought, may cause young trees to become stressed.

There is a difference between a free-draining dry soil in a warm, wet climate such as Great Britain and a sun-baked, frost-free California or South African soil.  During a cold, damp British winter, the temperature need drop by only 2-4 degrees Fahrenheit to kill plants. Half-hardy and frost-tender trees will only survive until the first “below average” winter.  Where the atmosphere and the soil are dry, frosty conditions are less severe on plants.  For example, my own garden in Northern Ireland is adequately watered with approximately 32in of rain each year.  Yet the top 6in frequently dries out to the point where I resort to watering young plants that haven’t had a chance to establish.  This is not the result of a hot, dry season but a lack of moisture-retentive humus in a gravelly soil, deposited before my time by a glacier.  However, once trees become established they will send out roots in search of water.
