Some areas are not blessed with soft, lush soil. Often times, the contractor layer the area around the house with topsoil that is 10 – 30 cm in depth. It is definitely adequate if you only plant grass in your lawn.
However, it gets tricky when you start planting other plants or flowers in it. Some plants root deeper than 30 cm, and they need more nutrients which cannot be found in rocky soil. A rocky soil would also mean that you need to find the right garden drainage ideas for it.
If you happen to have a hard soil under, here are some of the simplest way to deal with it.
1. Use Raised Beds
There is no way you can get rid of those rocky soil under. Consequently, you have to add more topsoil. Using raised beds in planting is a clever way to have your plants area to grow. The ideal raised bed is at least 15 cm in height—but it mostly depends on what plants you are planning to grow.
Since you only have around less than 30 cm of topsoil before it reaches the rocks, you can pick the plants with shorter roots. Some of these plants are alyssum, bellflower, dianthus, hawthorn, geranium, and many others.
Though some people would say that rocky soil drains well, it is not always the case. Sometimes, it can get too dry, especially for the plants that need abundant water. The best way to deal with it is to plan a drainage system. One of the garden drainage ideas in rocky soil is to slow down the flow of the water. It can be achieved by creating ditches or French sump.
Working in a rocky soil should not refrain you from having a great garden. With the right plants and garden drainage ideas, rocky soil can work as good as other soil.
