As I wrote about in April (See blog post from April 12), roses really appreciate a monthly dose of fertilizer from April through September. Well, here we are, in September, and it’s time to give them their final feeding before allowing them to start getting ready for the winter. This means letting any new growth that was encouraged by this latest meal to grow and harden off before the cold weather comes. if you fertilize too late, then the new foliage will get killed by frost and you will have wasted all that effort.
I will re-attach the drawing of where to fertilize, so that you don’t have to look back for it. Hopefully it will have become old hat if you have been feeding your roses monthly, but if not, it’s not too late and they will appreciate their last supper for awhile. I hope that you have had an excellent rose season!
