    I had new tall fescue sod installed in Sept 2012 and over the last several months it has started to yellow. I thought maybe it was just because it was winter, but I've been told tall fescue is supposed to stay green year round. I'm in the Washington, DC area. Does anyone know what is going on here and how I can fix it?

    Can you take a close up pic of the yellow areas? Close enough to see individual blades of grass.

    Most of it looks like it is just dormant. Something else to look into is: Chlorosis - Turf areas may become pale green-yellow, and plant growth may be somewhat stunted. In most cases this chlorotic condition is due to lack of nitrogen. If a nitrogen fertilizer application does not correct this condition, it is very likely that the cause is iron deficiency. An application of iron sulfate or chelated iron on turf showing iron deficiency will result in a greening of the turf within a few hours after application.

    Here is a link with some good information for correcting the problem: http://www.gardenguides.com/81606-fix-yellow-grass-lawn.html

    You guys had some serious storms in DC this year. Spring is a little late in coming. Wait for temps to warm up and fert with iron minors. Will be fine.
