Cobwebs on compost
For many years I have used a heated propagator in the greenhouse to start my seeds off. This year some of the seed pots have had a fine white cobweb develop on the surface of the compost. I can rub this off with my thumb but it comes back almost overnight. I remove the lid from the propagator during the day once the seeds have germinated. Even seedlings I have pricked out into new compost have developed this cobweb surface. Not all the seed pots have been affected. Any ideas as to what is causing it and should I treat it?
