Sheila,

I think one of the major differences between my garden and the one at Wooster was that when my spring starts, it progresses rapidly into summer. (Last year a local friend bought twenty roses and planted them in mid April and they didn't grow very much. Reason: allow a week or two for the roses to grow out into 'real dirt' and THEN the rose puts on growth. Except last spring we barely had five weeks of optimum temperatures. It was either very wet and no sun or too darned hot. ) The crop farmers felt it as well.

I would expect you are far enough north to have several months before 'summer warmth' hits like a sledge hammer.

The moss roses up in Ohio had huge bouquets of mixtures of buds and blooms and not all maturing at once. When one had three blooms, you could see several spent blooms, and about twelve more buds in different stages of maturity.

My growing conditions don't make for a long spring and early summer bloom for once blooming OGRs. It just doesn't happen. Heat and sunlight happen and I learned that if I don't / didn't photograph them at the start of their bloom,. the next week the bloom would be over.

In your part of the world, rose buds don't mature too fast, they get large. And the blooms get large as well.

In Maine we saw a rose (once bloomer) and the bloom was five inches across. (The tight petaled white one with the distinctive green pip at the center.) I grew that rose and had never had a bloom more than three inches wide and my petals never reached the size of theirs).

I do look forward to hearing about your mosses, I'd expect by year two, they will be magnificent.

Ann

Wait ... it said the disease was first discovered in CA ? Then why don’t they have it now ? I’m a little confused but it’s really not important.

I believe it was discovered on a native rose in a wild area where it didn't really have other roses around. It was used experimentally to eradicate multiflora and you the rest. : (

" in August. Samples of the roots and shoots were taken, and a lab confirmed the disease in February "

It's near criminal if the lab sat on samples for six months before doing analyses.

Allentown has had RRD nearby for over a decade.

The first RRD was NOT on wild multiflora or on multiflora gone wild.

That nobody noticed the problem until it was that widespread ....Clueless isn't just the name of a teen movie.

Ann, are you familiar with what happened at the Wooster garden?

Henry,

I had heard from them at the very beginning of their problem. The Plant Path folks at OSU had worked with Jim Amrine for quite a while so the knowledge should have been there.

I mourn the loss of their beds of Moss roses. I saw them in bloom one time and then I knew that my growing conditions were too warm for Mosses.

There was a single position in charge of the roses, and there was turnover in it. (This was about eight years ago.)

With all the active rose societies in Ohio, I am (yet again) surprised that nobody noticed.

Oh no Ann, I am trying mosses here. Henri Martin, Nuits, Cap John Ingram, and I just received William Lobb today. I guess I'll find out. I should be warmer than you, but have less humidity.

Thank you, Ann. I do hope they do well. Maybe if I don't go to Ohio I won't notice a deficiency either. Here's hoping. I think you might be right that we warm up more gradually.

I'm sure this is it. One the other hand in the last year or so we have had prolonged cool springs her in zone 6 (Brooklyn, NY) -- and then it warmed up very fast -- around June. But everything is so unpredictable. It may just have been a temporary blip.
