New sod at brink of death, need help.

dangerousstartFebruary 11, 2013

I just built a house.
It came with a freshly sodded lawn and they had the sprinkler system set to daily watering at 2am. I kept it there waiting to see it turn from some yellow to mostly green with roots attached. It hadn't happened after 3 weeks, so I added in another watering at 7:30am. After a week of no change I did a manual run just to find out that MY SPRINKLER SYSTEM WASN'T WORKING.

I'm talking to the builder now and they will fix the sprinkler, but the lawn isn't covered under warranty. (which I understand, I should've checked it to begin with but that's my own fault)

I've scoured all over trying to find out what I can do now and the only response on any post is "how have you been watering it?" and "here's how to check it"

My question is simple:

My new lawn has not had enough water for about a month and is more yellow than green, what can I do now?

Give it a good soaking and hope it comes back. What kind of grass? Saint Augustine?

Most Nurseries and fertilizer dealers have a good granular Potassium fertilizer, such as 0-0-22 with minors. I would ask around for that, or something similar. The potassium improves cell turgor, which will help the lawn recover faster by retaining more of the water you put down. The minor nutrients, such as iron, will also help with the color.

The question that comes to mind for me, is which part of the State are you in? If you've had cooler temperatures lately, that can stunt St. Augustine enough to discolor it. Lack of water shows up initially with wilting, rather than discoloration. This is easy to see in St. Augustine, because the leaves will fold up tightly right at the mid-rib, as the grass tries to increase the transpirational pull on the roots. If it didn't do this prior to losing color, then it's either reacting to winter temperatures, or there is a nutrient deficiency. Either way, a good potassium fertilizer with minor nutrients will help your cause.

One last note, make sure not to use fertilizer blends that include weed killers. St. Augustine is very sensitive to a group of herbicides, phenoxy acids, that are frequently found in weed and feed products. Look for active ingredients like 2-4-d or mecoprop (mcp) and avoid these.
