Q: We have zoysia grass and have never put lime on it. Should I do so now or do I have to test the soil first?

A: All lawn grasses benefit by having the proper soil pH. If your soil is too acid or alkaline, plants can’t take up the fertilizer you apply. You can get your soil tested quickly by following the instructions at www.georgiasoiltest.com. Even though centipede lawns tolerate low pH better than most grasses, you’ll get the healthiest growth by adding the right amount of lime. Lime takes a few months to dissolve, so waiting a week won’t hurt anything.
