Plants For Chalky Soil

Chalky soils (or those based on limestone) are usually alkaline, so have a pH above 7. They tend to be freely draining, stony and don’t hold onto nutrients very well. Therefore, to help your plants flourish, you should water regularly and dig in lots of composted organic matter as often as you can.
