They are also very sensitive to drought while in growth, and need magnesium
and food. The danger time is damp when they start to turn dormant. That is
when warm humidity causes pathogenic infections.
Deep planting can help to protect the bulb. It is important to remember
that they are mountain plants. Leaf mould is very good for them in my
conditions, topped with gravel for insulation.
