The Q&A Archives: Weeds all over St' Augustine lawn

Question: I have a St. Augustine lawn, and the types of weeds I have are numerous. I have clovers and different types of tall weeds. I even have a type of weed that just seems to grow like a tall weed, but grows against the ground and crowds out the grass. I moved into this house about seven months ago. The lawn also has bare spots. I have been using Bonus S, but all it seems to do is feed the weeds. I also tried Turf Builder. Do I need to start over on parts of the lawn with new sod? I have never had such problems with weeds. I even cut the yard at next to the highest setting on the mower, and it still doesn't help. I would greatly appreciate any advice you could give.

Answer: Brandon,

Whether you need to start over or not is hard to say. If most of the weeds are perennials it would be best to spray them and then restart with a new sodded area. I suggest you take samples from the various weeds to your County Extension Office for them to identify. Then a decision can be made as to the best product(s) to use for the weeds you have, when to apply them, etc.

The best weed control is a dense, healthy turf. Do all you can to develop a good, dense turf (regular mowing, deep infrequent watering and moderate fertilizing) and over a year or two you will eliminate the vast majority of weeds in your turf.

Thanks for the question. Please stop in again soon!
