My garden is only three year old,I started it the summer after I moved from the D.C. area to Frederick Maryland. So far my emphasis has been on my back yard. One side of this yard is a definite shade garden and about 2/3rds complete, The other side is definitely sun. I feel like I have the best of both worlds, but the sunny side has been a challenge because I have never had a sun garden before, and I am dealing with weeds, such as bind weed, that I have never confronted before.
