Rose woes
Hi all,
I'm growing some "Parade" roses down in TAS and noticed, just as a large number of buds are developing, some white powdery spots developing on many of the leaves. I'm guessing it's a fungal problem and seem to remember reading somewhere that spraying a 1/8 (ratio?) solution of milk and water might help. Is this correct? If not, can anyone suggest another way of treating this? TIA |

I believe the milk should be full cream milk, it needs that little amount of fat. -- John Savage (news address invalid; keep news replies in newsgroup) |

I'll give it a burl with plain milk and see how it goes. Cheers GH |

On his gardening programs on weekend radio Graham Ross was talking about black spot on roses, and he said that he has found that reconstituted powdered milk works better than the fresh milk. He said you should spray every week, or certainly at least every two weeks, so that any new growth keeps getting treated. -- John Savage (news address invalid; keep news replies in newsgroup) |

Thanks for this John, I've been spraying the fresh milk/water mix and it seems to be doing the job, however powdered milk will be a great deal more convenient. GH |
