Botrytis BlightGray Mold Rose FungusBotrytis Blight is a rose fungus also called Gray Mold, that causes the buds to turn black. These buds may not open. If they do manage to open, the flowers might be flecked with yellow or brown and covered with a gray fuzzy growth. The leaves, stems and growing tips will also be affected, and turn black also. Has this ever happened to your roses? Ever scratched your head and wondered what it was?Rose problems such as this is a moderately serious rose fungus.

TreatmentThe best treatment for Botrytis Blight is to prevent it! How can you prevent it?
Note: Be sure to dip your pruning snips in some bleach water to disinfect them, so you won't spread the fungus to other plants. I keep a bottle of bleach in the potting shed, along with a plastic pail. When I head over to the roses, I have it ready. It seems there are always flowers to snip off (deadhead). So why not be prepared? Spray the infected plant with this Organic Rose Spray It is very effective, for this and many other rose problems. By inspecting the bushes as often as you can, you can get an early jump on little problems before they turn into big ones!
