Betty,

How much fertilizer are you using? If you are, slow it down. Too much. Well, the rain you can do nothing about, so it doesn't mean the plant will die, it might even grow back for you, somewhat.

I haven't fertilized at all. Last year 1 stem broke off but this year 2 stems broke off, it still has one stem but growing at a strange angle. These stems that broke were about 1 and a half feet tall. I thought perhaps something chewed it off at the bottom, but I'm just guessing.
