Basic color question.

I have a couple of accounts that I've noticed seem to be showing some chlorosis, yellowing of the blades. It shows up real nice, too, since the rest of the grass is dark green and these spots are lime green.

The one is a St. Augustine yard and the other is a bahia turf plot at a factory. Both have been fertilized through the season, using Lesco 16-4-8 SCU.

Why are they getting spotty? Is the only way to take care of that by applying iron? Doesn't that wear off fairly quickly?

Thanks ...

chlorosis is a water problem, due to either to much water or not enough, i would check to soil to see how moist it is or how dry it is and avoid the chemicals if possible. try and correct the problem with proper water management before trying the iron.

Def. not nutsedge. These accounts both have irrigation systems that are used on a regular schedule ... every day, I think - both in the early morning. I'll try to get some pics of the offending patches this week.

Here are some pics that show what I'm talking about. This is the bahia, same story with the St. Augustine. I'll try to take some pics of the SA on Friday.

looks like chlorosis, how long do these places water? has the recent temperture been the same or has it been cooler? and how offen do they water( twice a day, ect...)

I had a customer with the same problem, he was over watering, and some of the lawn started to turn yellow and i had him cut back the watering at night and the lawn is greener in these spots and grows faster due to it not having wet feet for long periods of time at night now.

Joshua, I'm not real sure how long they water. If I had to guess, though, I would say at least 20-25 minutes per zone, every day, early morning. I'm not real sure that it would be a good idea to cut back right now, since we're in the middle of a drought ... I'll mention it to them, though.
