Managing Your pH
posted on April 27th, 2011 by Steve Schug
As we mentioned earlier this month, understanding the type of soil you’re working with when planting your Zoysia lawn is the first step in achieving the best possible results. Once you’ve determined soil type, it’s time to test its pH level to help you figure out what, if any, extra nutrients your soil may require.
While your Zoysia lawn can grow in a variety of soil types and pH levels, ideally your soil’s pH should be between 6 and 7. Since the pH of your soil determines how well plants absorb nutrients, it’s important to test it prior to planting – You can do this easily with a handheld pH meter.
If your soil tests below the ideal level, it is considered acidic. Acidic soil contains more sulfur and aluminum sulfate than neutral soils – And while acidic soil does help plants absorb iron more easily, it can also hinder the ability to absorb molybdenum.
Soil that tests above the ideal lever is considered alkaline. Alkaline soils tend to contain an abundance of lime or wood ash and help plants absorb potassium. However, alkaline soils can cause difficulty in the absorption of manganese.
Overall, most plants, including your Zoysia lawn, will thrive in a neutral soil. You can alter the level of your soil’s pH by adding granulated lime to raise the pH level or adding small quantities of sulfur to lower the pH level.
