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.
