Seeds in Situ + Physan20
I was wondering if using Physan20 regularly as a preventive spray kills the symbiotic fungi that, by all accounts, is around the roots of orchids. Anyone know or can hazard a guess ? I have heard reports of seeds germinating in greenhouses without any special care, so one would think that Physan20 doesn't impact germination, but one doesn't know - without asking ! Maybe those greenhouses didn't use it ?
If so then I will have a problem with germination in the seeds I have sown in-situ around a mounted Bc Yellow Bird's roots.
