Curly knobs on amaryllis
What are the curly knobs that appear on the leaves of my Amaryllis? My Amaryllis leaves have spots that curl into red knobs. Has spread from one bulb to the entire group. Cutting open the knobs I did not find a grub or anything. What is causing this?

It sounds like it could either be leaf galls or a fungus called red spot leaf disease. I would recommend repotting the plants (if in containers) with sterile soil and treating them with a fungicide, like neem oil.
