My lawn has turned quite yellow. Any ideas of the causes? I fertilized with a fall "weed and feed" containing iron about a month ago. I just had it it aerated. I am watering it quite a bit because I reseeded a couple of spots. The new seed is coming up really well. I'm wondering if it is some sort of nutrient deficiency, or maybe some sort of fungus problem?
The yellow lawn is the entire front lawn and is an even yellow color throughout. My back lawn is looking really good -- a nice even green. And it's getting the same amount of water and fertilizer as the front.
Yellow lawn for us means lack of iron. Our soil is clay-like here in Boise, ID. Not sure where you're at, but that could be what the problem is. Try a liquid iron, works faster than granual. Make sure you follow the instructions. You're suppose to water the area well before you apply. You should be able to find liquid iron at your local nursery supply center, Lowe's or Home Depot. Get the type that attaches to your hose for easy application. If you're area is dry keep grass watered after application. If lack of iron is the problem you should start seeing the grass green up in a matter of a few days.
Problems now are due to either steady low temps at night, below 60 degrees, where the grass is preparing to go dormant, or overwatering creating a Iron deficiency.
Try Milorganite (from Lowes), it's a slow release, but you'll still see the iron effect within a few days. It's a good product to put your lawn to bed with for the winter.
Psst. Come over here, I'll whipser a secret to ya. Shh, don't let anyone else know.
Get some epsom salt. Dilute it to about a teaspoon to a gallon of water and using a standard watering can, water your lawn. If you have one of those garden hose sprayer jobs, mix 1/4 cup epsom salt to the container iwth some water and then attach the hose and spray the lawn once a week with this.
Tip: You'll be sorry. This will create a lush, green and vibrant lawn that will grow twice as fast as any other lawn -which means you will have to mow it more often than anyone else has to mow theirs.
riveree - I concur about Milorganite. It's relatively inexpensive and 'organic'. I didn't realize how organic until I googled it... Ewww...

it consists of processed sludge from the Milwaukee Metropolitan Sewerage District Jones Island Wastewater Treatment Plant in Milwaukee, Wisconsin. The fertilizer is made up of microbes that have digested nutrients from the sewage stream along with added iron, used to strip phosphorus from the waste water flowing into Lake Michigan.
The name Milorganite is a contraction of the phrase Milwaukee Organic Nitrogen
Milorganite has been banned in many areas for cancer causing substances in the material.
