Please can anyone tell me what this is and how is best to get rid of it. We have been away for a couple of months and I find my sage plant covered in these red threads. I think they arrived with some oregano last year but now I see it as a potential major problem. Should I cut the sage down to the ground or spray what is there with something.
I have pulled lots of it off but will never get rid of all of it that way.
Help would be much appreciated.

Hi Verity, I've seen Red Thread as a fungal disease on lawns but never growing through plants like this. I'm sure one of our members will be able to shed some light on the problem.

It looks like, dodder, Cuscuta sp., maybe Cuscuta europea? I would get rid of it as soon as possible, preferably burn it. I bought a basil with a similar threadlike growth that nearly suffocated the plant and I was advised to destroy it immediately before it spread to my other plants. I believe that was Cuscuta epithymun, which is paler, but which behaves in the same way. Dodder can be highly invasive, see more about this parasitic plant here ftp://https://web.stanford.edu/~cbross/dodder.html .

Amazing parasitic plant - thanks for the link Jorun made fascinating reading.

Thank you very much, will cut sage down to the ground and check regularly to make sure it does not re-emerge.
