Trees for Chalk Soils


Chalk soils have a very high lime content so can be harmful to many trees.

That being said, calcium and magnesium limestone in the wild supports a very diverse range of plants so the gardener need not be entirely defeated by theses conditions.

Chalk is more difficult when there is only a shallow layer of soil above the rock since this leads to soil drying out quickly.

Attempts to fight nature by planting your favourites will almost certainly fail.
