I have white mould in my compost
Sometimes when you open a bag of compost you may notice a layer of white mould on the top or part way through. Although unattractive this is in no way harmful to you or your plants and is caused by a saprophytic fungus that feeds on dead and decaying matter and is in fact essential to healthy plant growth. There is not a problem with the compost and it is safe to use on all plants including fruit and veg.
