I've ransacked Aggie Horticulture's web site pretty thoroughly to no avail. I've tried to contact our turf scientists, but haven't gotten an answer yet. Will check with the county agent next. If not there-I'll try out oak specialist. My neighbor has an oak, but he isn't having this problem. However, he is an avid gardener and does a lot of watering and fertilizing anyway. Thanks. I'll get to the 'root' of the problem yet. :) >I'm in agreement with Barb since you described the exact dimensions. I think >you're moving in the right direction too.
