Ok, I have been reading around her for a while now, and I have a question. I have seen conflicting information as to the source of thatch, in the very same thread I saw two starkly different reasons, one said too infrequent waterings, and the other was too much watering. I know it is normal to have some thacth, and that it really doesn't come from clippings as many customers suggest but........ WHICH IS IT???????
