I planted some Rose Of Sharon a few years ago. The rabbits have been feasting on them, but the people on this forum told me to use water with a little dish soap. Well, it WORKED. My rose of sharon are now 3 feet tall and for the first time they are blooming.My question is: what if anything can I do to they to keep them healthy? Do they need any special food or should I just use some miracle grow? thanks in advance. :-D
