Reds spots on pancratium

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.
