The compost that we purchased from the store, seems to have come with small fungus spores that come up during the day and by the next morning turn grey and wilt away. This seems to be causing mold spores to cause the leaves of our tomatoes and our cucumber.

Does anyone know what to do about this? We don't have the luxury of more compost. It is too expensive this far into the gardening season.

Any ideas will be welcome.
