Hay Kernel: I agree with everything you have said so far about oak root fungus. You are right on the money. The fact that you did not see the honey mushrooms growing from decaying host roots might be the best way to assume that the fungus was no longer present in infective levels. Is there a reference that would support your decision to add ammonium sulfate? Does the oak root fungus really need it in the same way as regular plants? Just wondering, Baldito | ||

As I said, I dumped 40# of ammonium sulfate on it over a few months and after a year or two, it went away, Don't know how much good the ammonium sulfate did. I reasoned that if I over fed the ORF, it might die. | ||

Mel, did you have to have recourse to chemical treatment? Or did it eventually go away? Jeri Jennings | ||

I agree with Cass. We had an area in the Heritage with ORF resulting from dead roots from a tree that was removed. I tried treating it with massive amounts of ammonium sulfate, but it took 5 years before the mushrooms no longer appeared. The whole area needs to be dug up to remove rotting wood and I'd sugest that it remain fallow for a couple of years after that. Perhaps a test rose could be planted during that time. If it doesn't grow well, wait some more. | ||

That is great news, apart from the oak root fungus. Since it loves water and roses love water, I don't see much of a solution without extensive preparation. John, do you think they are willing to solarize the soil this season, build up a very slight mound to make sure drainage is perfect, and remove as much of any wood barky stuff in the soil as possible? Some people plant in pots, but that's a serious restriction for something as large as a Tea. Hopefully someone who has succeeded in controlling ORF will respond, methyl bromide aside. | ||

The proposed area is betw. Albas and the Chinas. There's a bed that has languished and had some problems with an oak fungus in the soil that Wen thinks affects some roses. Now, if anyone knows anything about oak fungi, weigh in. Last thing we want to do is condemn Hoag House Cream and the like to a lingering death. | ||

John, that is GREAT news! It should be a terrific addition to the garden. Do you know whereabouts it is likely to be placed within the gardena? I guess we'd best start collecting some plants for you, eh? Jeri Jennings | ||

FYI. Wen Wang at Descanso is going to propose a section on(tentative title) "Lost Roses of California" to the higher ups at the Garden. I think a rose rustle article and my incessant yammering got him going. There's even a bed available and I told him(presumptuously) that old/lost rose folks would be happy to provide stock and stories of where the roses came from.I am SO excited. Thak you, Jeri! |
