What is the role of rocks in the rock garden?
Rocks play an important role in the growth and health of many plants just as they do in their natural habitat. Rocks affect the immediate environment in a number of ways to allow the plants to flourish:
- Rocks shelter seeds, allowing them to lodge and germinate,
- Runoff from rocks provides supplemental water and nutrients that help the plant become established,
- Shade from rocks keeps the soil around the plant from drying out and protects the plant's roots from heat from the sun,
- Rocks also provide a protected, competition-free location in which the plant can thrive.
