Growing Grass On Rocky Soil

Do you want a beautiful lawn, but can't seem to get one to grow because your soil is full of rocks? Growing grass on rocky soil can be challenging, but it's not impossible.

Here are some tips on growing and maintaining grass on your rocky soil:

Working with the Rocks

If you have the means to use a tractor to drag the land and remove surface rocks, by all means do so. If not, till the land removing as many rocks as possible.

When starting fresh, your best option is to get a truckload of topsoil. Spread the topsoil evenly over the area you plan to seed. Your seeds will have a better chance of thriving in topsoil that can be kept moist. Rocky soil dries out quickly. Even if you have dragged your land, more rocks will probably surface over time.

Choose Wisely

Soil with rocks tends to lose nutrients rapidly. Couple that with the fact that it dries out quickly, and you have two challenges when it comes to choosing what kind of grass to plant.

You will want a grass that is known to grow well in your climate, and is drought tolerant. Plants, flowers and grasses are often classified by the zones in which they grow well. The U.S. Department of Agriculture has a plant hardiness zone map you can refer to if you need to know what zone you live in.

A few grasses that lend themselves to the ability to thrive in rocky soil are:

Bermuda grass – This grass grows best in zones 7 through 10. It is a fast growing grass and has deep roots. Bermudagrass is drought tolerant.

Buffalo grass – This grass grows best in zones 4 through 8. It does well in full sun and with well-drained soil. It is drought tolerant and has low water requirements.

Fescue – This grass grows best in zones 4 through 7. Fescue is a low maintenance grass, is drought tolerant once established, and holds up to harsh winters

Zoysia grass – This grass grows best in zones 6 through 9. It develops deep roots, only needs occasional watering, and while not as drought resistant as others it usually tolerates rocky soil.

A landscape professional will be able to help you choose which grasses are best for your location and soil. All grass requires some maintenance whether it is watering, fertilizing, aerating, or mowing. If there is any question as to how you should care for your lawn, bring in a professional (such as Valley Green Companies). Don't give up on your rocky soil.
