Choose the plants for your rock garden. Plants that grow close to the ground and clump together work well in most rocky environments.
Choose the right location. According to the Montgomery County Cooperative Extension, slopes and uneven terrain are ideal for creating a rock garden.
Clear the area of debris and the top 6 inches of soil.
Design the layout of the rock garden. Rock gardens are designed to look natural. To achieve this appearance, clump rocks in masses with sporadic spaces in-between.
Set rocks into the ground so that 1/3 is buried in the soil. Use small but similar rocks as mulch.
Use a small shovel to plant the flowers, perennials or foliage plants in the spaces between the rocks.
