I am wondering if it is to late in the year to give my perennials a dose of fertilzer? I am in zone 3b, in the NW corner of the state.
I am particularily wondering about my endless summer hydrangea. This is the first full year I have had it, I planted in spring 2005. It did bloom, but I think it got to dry while I was out of town for 3 weeks. All the flowers dried up. I have dead headed it, and am right now giving it a nice deep watering. But am wondering if I should put some miracid down.
