Our botanical garden rolls the bulbs in Plantskydd (liquid) and lets them dry then plants them. Nothing will touch them then!!! Whew smelling. I spray it around my garden and on my plants to repel moose and it works great.
opsss. Forgot to answer question about crocus. You know, I have never noticed. I do know that I have not taken any pains to plant them upright and I have plenty coming up so not sure. When they are laying around in a bucket for a while they do sprout at the top end but so do lilies and tulips and they manage to reorient their stems so why not?
