>What is the reason that you lift the [colchicum] bulbs?

These are stock plants that I keep in plunged mesh pots so I can keep them 
separate and clearly identified, and I usually sell the surplus if they are 
healthy. I lift them every other year to change the soil and divide them, 
since they're in a confined space.

However, it's also beneficial to lift and divide garden colchicums at least 
every fourth year, because the corms become very crowded and try to cope 
with that by plunging ever deeper in the soil, and they they may not flower 
so well, because they get very attenuated.

I hope Arnold's bulbs aren't getting washed out by the torrential rains 
recently experienced in, I think, the area where he lives?
