 It happens when the bulbs are not
 warm enough, (or dormant), and therefor
 not using as much water as they have in the compost. I find
 that chemicals
 are not needed, improved conditions allow the bulb to heal.
 The first thing to do is get the compost drier, and make
 sure that it has
 plenty of air content. Then wait until the bulb tries to
 grow and needs
 water. Also, ensure that temperatures are adequate for the
 species in
 I believe that mites can exacerbate the problem.
