I've always heard that you can take white plastic grocery bags and tie them in different places - it mimics the deer's tail that signals to the other deer that danger is near - they will avoid the area. I don't know if it works but it is a nice concept
I have had a lot die on me. I did manage to grow some truely amazing pumkins. Truth be known - I just forgot to clean them up from Halloween. Altogether I got 3 large pumkins and 38 ghords.
Now ask me how many of my periennals came back out of about 3 dozen - only two. My white pampas grass and a piece of something my grandma gave me. It is still going strong.
