zoysia yellowing lawn
I re-sod my lawn in late November. It is the Zoysia variety. I was catching nicely, but within the last 2-3 weeks it started to yellow and look like its drying out. I stuck my finger in the ground and the sod base was kind of mucky to the touch. The yard has a very slight slope to it. My assumption was that the water was settling in that area and saturating the roots.
It was recommended to put potash down to help the roots.
How do I get the yellow patch to start growing again?
