Ruthless Defoliation

As I said before, my Francis Meilland had rust. This is only the second time that I've used a non-organic substance on my roses. But I had tried just removing the infected leaves, , , it didn't work.

So I sprayed with Bayer Advanced Disease for Roses last weekend. Just this morning (no wind) I very carefully removed all diseased leaves on FM plus some on the roses closeby. I also cleaned up all old leaves from the bed and bagged them all and into the trash.

I had to remove leaves from almost the bottom half of the FM. The others weren't nearly so bad. I will then respray both older beds at about 14 days and see what happens.

If the FM becomes re-infected, he's history.

This rose won awards for being a 'no spray' champion...So far, I had to have one destroyed and NOW, this one has the worst case of 'nobby knees' you've ever seen..It's a good thing that he's at the back of the garden where only the top of the bush can be seen.

RE: Ruthless Defoliation

I'm going through the same thing with my HT. The cluster of cages may be affecting air flow. I didn't have the problem last year with rust and PM. I had fewer roses and fewer cages. I sprayed, fertilized and increased my watering. My old garden roses on the slope are clean.

My opinion now is roses are easy, HT roses not so easy.
Deer, fungus, insects.
