How to Lower Soil pH

If you are having problems getting plants to grow in your yard, you may have high soil pH. Most plants prefer a soil pH of about 6.5, so anything higher than that may be creating a problem for your plants. Upon determining that you have a soil pH problem by using a soil testing kit, here’s how you can lower your soil pH and transform your plants’ health.

Lowering Soil pH with Compost

If you live in a region with clay soils, you will likely have a soil pH around 7.5 to 8.5. To lower the pH in this soil, simply add a good deal of organic matter and compost to your soil before planting. This will lower the pH and also break up the clay soil, which can help with drainage issues generally associated with clay soil.

Lowering Soil pH in an Existing Garden

If you have an existing plant, tree or garden that needs its soil pH lowered, you can use sulfur pellets. You can generally purchase these in 50 lb. bags at home and garden stores. Adding a handful or about a ¼ cup of these pellets at the base of plant is quite effective in lowering pH. These break down very quickly with watering, though it is not recommended that you use these more than twice per season, as they can burn your plants if overused.

Verify that your soil pH is too high and makes these simple adjustments to have a healthy, fruitful garden.
