My St.Aug turned from a nice deep green color to a bright yellowish color over nite after applying Lesco 26-2-11. It’s in diff area’s but about 50% of the yard has changed. Does anyone have any idea’s. My last treatment before this one was about 10 weeks ago which was lesco weed/feed. Should I run my sprinklers even more. I’m running them 3 times week now it’s been real dry here in Tampa Fl. Also could I hit it with Iron or should i leave it alone. Any help would be awesome. Thanks

I also forgot to mention that I used a handy spreader the kind you hold in your hand. My broad cast spreader took a shit. I’m wonering if I just applied to much in certant area’s and not enough in other’s.Whats would be the best way to fix this problem do you think the ph is messed up. Should i hit it with lime. Thanks

Hi:

How long do you water each zone?

Hi I water about 20min per zone and it’s reclaimed water.

Do you think it could be fungus

Could be many things. You could have gotten too much fertilizer down and burned the grass. You could have disease or fungus.

I would treat the lawn for fungus. And no, I would not water the lawn more as that promotes fungus problems.

It turned yellow from too much nitrogen. It should clear itself up. St. Augustine needs a lot of nitrogen but at a slow feed. Think about getting more potassium into the root system for uptake of the nitrogen. Grass and roots have got to work in harmony. A good micro-nutrient mix with iron would help significantly.
