Whit, looks good brother.....I am in west tennessee at probably a much lower elevation than you are and ive seen how the mountains start greening from the bottom up, thats why i thought that your crops would be behind mine. they should thicken up thru-out the spring, IMO.
Latt,sounds like its going to be a job. I always have had what i thought was a leaf density issue, however i haven't done anything about it. I have a large amount of hickory, oak both white and red, maple and popular. Do what you feel you need to do, 20lbs is alot. Good Luck
Oh here is ya another pic.
