Re: Easy rose trend

I asked someone who recently interviewed Bill Radler (hybridizer of Knock Out) about the deadheading issue. Below his reply:

*********
I was at the Boerner Botanical Gardens Annual Meeting and Bill was the keynote speaker. He gave a long presentation and it went into great detail. The deadheading issue came up in his talk.

Although I recall his comment was more a caution that deadheading Knock Out was a waste of time rather then actually causing harm. More like, you need to deadhead other roses to induce more blooms, but that is not necessary with Knock Out. It will continue blooming.

***********
Maybe this will put this issue to rest.

That seems contrary, since the idea of deadheading most roses is to
STIMULATE new shoots that will bloom some more. With most roses, letting
hips set causes the plant to slow bloom production and put energy into
developing the hips.

Carolyn Ulrich asked:

what's the reason for not deadheading Knock Out?

According to Bill Radner, Knock Out's creator, deadheading triggers a
hormone that curtails buds from sprouting on that particular cane. You
can
thump the dead flower with your thumb to send the dried petals flying, if
you are a neatnik and must have perfection, but you should leave the hip
with stamens intact.
