Hi, I have a 4 year ild Ilse Krohn Climber which flowered beautifully the first year. We moved it and it grew vigorously for 2 years, but did not flower. This year we were elated to see HUNDREDS of buds, but when they opened they were tiny single blooms only abut 1 inch across, with the classic "wild rose" sort of makeup to them. What happened??? Any way to fix this??? THANKS!

I am guessing that your Ilse Krohn Superior was budded to a R. multiflora rootstock and that somehow, the rootstock has overtaking Ilse.

Hi cass, thanks for your reply. Is therre any way I can reverdse the "Takeover" or is the rootstock now and forever in control?

The extent of the takeover will decide whether Ilse can be saved. If you carefully remove all the suckers of the rootstock and leave only the canes of Ilse, you might save your plant. Most rootstocks are far more vigorous than the roses that are budded onto them. As a result, rootstocks allowed to sucker will eventually overcome and out-compete the scion, which will die off. So the key is: are any of the remaining canes Ilse?

Reputable growers carefully de-eye rootstocks to discourage suckering. Cheap, poor quality plants are more likely to sucker. I've also heard that in certain alkali soils, multiflora rootstocks are inclined to sucker, but I have no personal experience of that problem.
