Holly Tree

I have 3 very large Holly trees, all at least 40' tall and at least 20" round. The smaller of the 3 is within 8 feet of a larger one, this smaller one had gotten dark damage at the base, which a section of bark came off about 2 years ago. Since then it has lost 65% of its leaves, the leave it has are dark green and healthy looking. I do not believe this tree is dead or dying just in distress I hope. Please please help me in you can! The picture of the base is black from tree wound paint I applied last year. The other pictures I am sure you can see the thinning tree on the left.

Lawn of Tall Fescue

I"ve had a lawn of what I think is clumping tall fescue that I think may have been sodded over ten years ago (we've been here for ten years). Last summer, for unknown reasons, maybe grubs, about half of it died - see the pictures. It looks and feels like a cow pasture. Last fall I planted what I thought was a match - another fescue, but it does not match at all. Not sure what to do. I would like to plant more matching clumping tall fescue and would like to know where to buy it and what it is called. (I could not download a picture.) Thank you.
