KitCMC is that all the tuber’s resources would be directed to the remaining sprout instead of growing many additional.
Cate, I've never noticed one stalk growing from a tuber is any more, or less, robust than multiple stalks growing from a tuber. If the plants are given ample room and fertilizer it should make no difference.
KitCMC Are there other negative impacts of this “technique?” I only have one of this variety and don’t want to inadvertently make it unhealthy.
I generally don't like to do any more surgery on a tuber than is necessary but this could be a personal phobia. I suppose, since bacterial infections, such as crown gall, are initiated by wounding the tuber, it could possibly increase those infections. I doubt if the increase would be large enough to measure.
