I live in the DFW area and have a Delmar St. Augustine lawn. It was sodded at our new home in April, 2003. Before building our house, the land had been farmed. I have continually had problems with the grass blades turning yellow from the tips down.
I have aerated the entire yard, put down compost, lava sand, greed sand, corn meal, dry molasses, and an organic fertilizer. Nothing seems to help the yellowing of the grass blades.
Since my non-organic neighbors on both sides have beautifull bermuda lawns, I do not believe this is a soil problem. It seems to be a problem with the St. Augustine grass.
Please help! I do not know what else to try.

PS: I have put down corn meal several times because I thought the grass had a bad case of Brown Patch last year. However, I am beginning to think it may have been chinch bugs.

I wish I was more familiar with the different varieties. Could it be that Delmar is more yellow than the rest?

Comparing St Aug to bermuda in color, St Aug will ALWAYS look yellower. Could be you're at full greenness but compared to the bermuda it looks yellow to you.

I'm not familiar with Delmar either, but as far as chinch bugs go I'm fairly certain that it's too early to be seeing them actively damaging your lawn. They like to attack when it's hot and the st. augustine is stressed by other factors such as not enough water, fungal issues, etc.

In order to check for chinch bugs you can do either of two things. If they're thick you can simply brush your hand across the turff and you'll see them down deep. They're little so know what it is you're looking for! :) Cutting the bottom out of a coffee can, tamping it into the soil and filling it with water will flush them to the top. With either method you're going to have the best results in finding them by checking at the area where the damaged turf borders the healthy stuff. Typically they start in an area and spread outward, eating as they go.

In any case I'd call the place where you bought the stuff and ask them what they think. Miller Grass in NE Dallas is where I've always bought my st. augustine sod and they're usually quite helpful identifying problems I've had.

Good luck!

over watering or under watering st aug will make it turn yellow!

pull a PH test and find out where you are on PH,,,,,then if you want to make it green after fixing the PH issue (if there is a PH issue) apply as much milorganite as you want.
