Why won't a mature blood orange tree bloom?
I consider it mature, it has been in the ground for about 6 or 7 years. It was in bloom when we bought it, but has failed to bloom again. At first my husband would fertilize it in the spring for several years and nothing. Then for the past few years, he quit fertilizing it. Still nothing. It gets lots of sunshine.
He wants to do away with it, but I protest and say that at least the butterflys get to lay their eggs on it.
