If you have problematic landscape features such as a moderately steep slope, dry soil, and rocks, you have the perfect environment for a rock garden.
Rock gardens mimic an alpine environment. For example, imagine you are on a long hike and you finally emerge above the tree line. You look around and see slopes with loose rocks, low-growing vegetation, and maybe a few wildflowers in crevices between boulders. A rock garden intends to recreate the feeling of this landscape.
To create a rock garden:
1. Start with a small open area. An east-facing slope with poor, rocky soil is ideal.
2. Adjust the soil to create a mixture of one-third each soil, small rocks, and something with good drainage, such as sand. Add some larger rocks into the soil. They can be arranged to your liking by adding a lot to create many crevices — a crevice garden — or just a few to accent the space.
3. Add plants that thrive in dry conditions, experimenting to see what works for your conditions.
4. Rock gardens should not need applications of fertilizer because the plants derive nutrients from the rocks added to the soil.
