Can you identify this disease? #931663

Asked May 14, 2026, 11:17 AM EDT

I put my potted amarylis in a paper bag in my basement for a few months, then try to grow them in early winter. I do the same with my container of Agapanthus - I bring it inside in the fall and put in my basement, covered in a paper bag, to pull out each spring. I have noticed white strand-like growth on the plants and wonder what it is and whether I can get rid of it, or whether I should dump the Agapanthus and amaryllis. Fungal disease? Also, I am currently finding very small worms in my vegetable garden as I'm preparing my beds. I wonder if they are young earthworms or jumping worms. They are too skinny & small for me to see clitellum & they are not squirming / thrashing when I touch them. Leave them be or remove them?

Expert Response

Thank you for contacting the UVM Master Gardener Helpline with your question about the fungus on your plant and potential jumping worms.

I asked for input from Ann Hazelrigg, who is the Director of the Plant Diagnostic Clinic, for assistance with your fungus question. She provided the following response:

“Yes, looks like fungus on the agapanthus. It is probably a result of being in a moist cool basement and is not an actual agapanthus pathogen but something more opportunistic. I would remove as much as you can of that above ground tissue and destroy. I bet once the plant gets outside in the warmth and sun, the new foliage will grow out just fine.

“I can't be sure on the worms. They would be really small right now if they are jumping worms, but it sounds like they are not thrashing around so must be something else. Even if they were jumping worms, it would be tough/impossible to eliminate the population from handpicking.”   End of quote

On the UVM Master Gardener Resource Web Site under “Introduced (Invasive) Species” there are a number of documents about jumping worms that you will find helpful. In particular, you can refer to the “Jumping Worms Best Management Practices” document for more information about identifying the worms at various life stages. If you do have the worms, you can drop them in a cup of soapy water to destroy them.

I hope this information is helpful. If you have any additional questions, please feel free to reach out.
