HELP! Last fall I left a very large pile of leaves on my lawn and hence, I now have a very large brown dead-grass area. When should I reseed this very large space? And, how do I know what type of grass seed to use. Also, I have lousy soil, actually it is clay. So any advice on what to do? Any help is very welcome! I guess you can tell I live in Maryland, so, of course normally flower seeds do not get put into the ground until after May 15 (rule of thumb).
