Chris, I live in the inner ring of subs of Detroit. I have low laying clay loam that doesn't dry out well, so I feel good if everything gets planted by Memorial Day. So, as you can imagine, I don't worry much about LFD (my LFD=May 12). While rummaging through a used book store this winter, I found a book that may be of intrest to you. The Organic Gardener's Home Reference by Tanya Denckla, published by Storey Communications. It discusses the information you seek in detail. Plus a lot of other subjects. I would try my local library to check it out. If you live in SE MI and your library is a member of The Library Network, there are seven member libraries that have the book. And no, your thinking appears to be right on track. HTH RM |
