Top Dressing a lawn

My front lawn is uneven and has some dead spots caused by dog urine, so I would like to top-dress it and over-seed. What material do you recommend for top-dressing (I am assuming .25 to .50 inch of top-dressing material) and should I spread the seed prior to the top-dressing? Finally, once the new seed is growing, how to I keep from getting mower wheel ruts in the newly dressed lawn?

Thank you!

Probable Emerald Ash Borer infestations in Arnold

There are 12 ash trees on Clausen Lane in Arnold that are very likely infested. All have varying amounts of die-off- probably from 10 to 50%, and characteristic 'D' exit holes. At least one tree has split bark with the squiggly bore patterns inside. These trees were planted as saplings in 1999 and are now 40-60 inches circumference (breast height). We have just treated the trees with imidacloprid soil drench this past week.

What is this tree?

I am requesting a street tree from Baltimore City. A tree which the City planted across the street from us seems ideal. I'm trying to find out what it is so I can request the same, and am attaching 3 photos of it. It was planted 8 or 9 years ago. Here's a close-up of a leaf; they alternate along the branches, usually growing in little clusters of 2 or 3 leaves. They go a beautiful yellow in the fall, and linger on the tree fairly late. You can probably see the bark in the "root" photo: it's smooth, grey-ish, motley (peeled-looking) in places, occasional patches of ordinary rough vertically-oriented tree-bark. I can send additional photos if it'd be helpful. Could you please tell me what it is? And whether this tree has any problems in older age that might make it a poor choice? So far it is doing splendidly. Thanks!! (sorry, you may have to rotate a couple of the photos.)

Gambles Oak Infection? Black growths on trunks and branches

Hello, I live in Colorado Springs and have some sections of Gambles oak that have black growths on the trunks and branches. I have attached some pictures showing the growths. The trees in the affected sections have less leaves and growth is not as vigorous. I would like to know the following: 1) What is this black growth? 2) Is this growth contagious? 3) Can you treat the trees to remove or stop the spread? 4) if you cant treat the trees, how can you remove and prevent reoccuance? Any information would be really great.

hosta problem

I have 3 hostas in a bed of other hostas that are all showing rust spots and wilted, almost transparent brown sections of the leaves. I don't know the name of the hosta, but the leaves are generally about 5-6" long with the width at the widest part about 2-3". The are a solid lime green color and one clump is probably 3' diameter, but only 12-18" tall and very dense. They get some morning sun, but by noon are in shade. I have some slugs and grubs, but have not noticed any of them or any other insect on the leaves. This is the only variety that is showing this symptom. I checked out the pictures for the hosta virus X, but they are not similar.

What is wrong with my peach tree?

About 2 months ago, I noticed my peach tree's leaves shriveling. Now they have fungus-type lesions on the leaves, and the tiny peaches turned redish brown. This has only happened to one of three trees. The other two are fine.
