Q.Can St. Augustine Grass And White Clover Grow Well Together?
My soil is sandy, not very fertile, and I’ve pulled lots of crab grass out. I’d like to add white clover to my St. Augustine grass to help add nitrogen naturally and help crowd out crab grass next spring. Will that work in Florida? Or will the clover crowd out the St. Augustine grass?

The first article includes some information about white clover to consider before adding it to your lawn. It does say you can mix it with a high traffic grass to avoid the dead spots from walking on clover. Also note that clover may shade the St. Augustine, causing dieback. (you may want to use the microclover) It also may act as an annual in Florida, so you may need to let it mature enough to produce seed for reseeding, or add additional seed each year. I also included a link to find your local extension service, who can guide you on any merits or pitfalls in adding clover to your lawn in Florida.
