I just finished. I doused them today again with the same stuff. We have been having nice rains and it even rained again last night. I figgure between the rain and fertilizer they should really get growing nicely. Lots of green growth already since the last time I did this.
Spray day is really a big job when I do it like today as I not only did the fertilizer but then I just started again with the roses as they needed there fungicide spray.
