We put new turf down over a very small area last September and it was absolutely fine for quite a while. During the worst part of the winter we noticed it looking a bit worse than a lawn should look at that time of the year, sort of damp and lots of little worm mounds on it. We convinced ourselves it would be OK by spring but it looks dreadful. What happened? The house is for sale and the lawn is a definite minus point at the moment, what would be the cheapest "quick fix" ?
possibly the new turf is a differant type of grass or soil type thats made it look odd, this will usually blend in with time, but of course this dont help you right now, so I would suggest a lawn tonic, I think theres one called something like 'feed & grow' that might do the trick ! Good Luck.
September is fairly late to install sodded lawn so it may not have had sufficient time to establish a root system. Add a light application of a high nitrogen content fertilizer (it's the first number in the series of three in any fertilizer). Then, be sure to water it extensively. At least once a day. It should come back for you, but right now it's trying to establish itself. It wouldn't hurt to seed it lightly with a good fescue or blue grass seed... Good luck!
