If you have rather dry soil in your garden, you should not plant very thirsty trees there. These would have to be watered repeatedly and frequently. By the way, sandy, permeable substrates are often very dry.
Which trees need little water?
Drought-tolerant trees that require little water include maples, robinias, and some Mediterranean trees such as olive or citrus trees. You can recognize these trees by their small leaves and a loose, airy crown.
Drought-resistant trees and shrubs
Most native tree species need a lot of water and therefore thrive best on loose, humus-rich and rather moist soils. On the other hand, trees from the Mediterranean region are relatively insensitive to drought, as they are used to a dry climate and poor soils. However, olive and citrus trees are not hardy in our latitudes. All types of maple and robinia also need very little water. You can recognize drought-tolerant tree species by these characteristics:
- The leaves are rather small.
- The tree crown is very loose and airy, with few branches.
Trees tolerate drought better if you mulch the tree disc at least ten centimeters thick. The mulch layer retains existing moisture better in the soil and protects against evaporation.
Tip
You should also not plant the tree within a lawn, as grass draws a lot of water.
