Grass blades are yellow/green...

WestchesterGrower(Lower NY)May 31, 2009

Hi,

I seem to have this issue every year.

The grass starts off beautifully, and in late Spring the blades start to turn a myriad of colors. Some have yellow in the middle and green on the bottom or top. Others have yellow bottom and green top, etc. I figure it may be fungal, but we are not in a dry spell and it seems to be getting worst. I should note that I have gone organic and so far have used only corn meal and milorganite in early Spring. So I was thinking it may be lack of N, but this happened when we blasted the lawn w/ chemical ferts as well.

Any ideas? We do have some grub issues, but I thought that produced more severe areas of yellow compared to an overall issue throughout the lawn. The grass is still growing quickly and has strong roots. Type of grass? I believe we mostly have fescue and perennial rye.

Thanks greatly!

I don't know about other years, but lots of people are reporting mixed yellow/green blades this year in our area. It seems to get worse after yet another rainy spell. So far, nobody is connecting it with fungus or disease. Post a close-up picture if you want us to match it to what everyone is seeing this year, and to make sure it isn't anything more serious.

It could be iron chlorosis. A lack of iron sometimes causes grass to turn yellow. Sometimes there's iron in the soil but it's not available to the grass due to pH (either too high or too low). Too much water can also cause it.

Don't know about your area (check your Agronomy depts at your Cty Extension or local colleges) but I just got an "Alert" email from NC State Friday warning of possible fungal and insect problems due to much rain and higher temps. I immediately got some fungal treatment and applied Sat morning.

I'd contact your folks up there before you lose you grass.

I don't see anything looking like fungus. It looks similar to other postings that we're hearing about - maybe you have a little more brown and a little less yellow, but I'd watch and see what happens as it dries out.
