Question
I recently reseeded my yard after dethatching and using a power rake.  The grass was showing in 6 days and except for a few bare spots, it was looking good.  Now it seems to be showing signs of loosing the new green color.  Almost turning to a yellow.  I live in Zone 9 and planted tall fescue, Kentucky 31.  I have a sprinkler system and am now watering every other day and am going to cut back to once a week soon.  I had the yard fertilized with a grandular by a yard service at the time of seeding.  I also have an unusual amount of mushrooms here and there.  Many different varieties.  Would you have any thoughts or suggestions.  I hate to loose the entire yard as it is at least an acre or more.  Thank you in advance.  Mary

Answer
Ms. Manley:

The timing of the seeding should have been ideal.  In zone 9, irrigation is needed for fescue.  However, fescue is fairly marginal for a zone 9 lawn.

It sounds as though you prepared well, got good initial results.  If you are experienceing the same drought as the mid-east coast, then the stress may appear as yellowing, even with irrigation.

Since you mention mushrooms, I wonder if a fungus has begun to take the young grass.  To be sure, an analysis will be required.  Your local ag agent should be able to provide that.  With fall temperatures and moisture, fungi can thrive.

If the culprit is fungus, you can treat easily.  Just be sure to do so before the winter rains begin, if in Florida.

If treatment is successful, you may reseed throughout the winter to perfect the stand.

Best wishes.
