Blue powdery mould in compost.

Gabriel8500 added on April 15, 2019 | Answered

Hi, I’m VERY new to composting and I have decided to make my own compost. I try to mix it in every 2 to 4 days. Although I’m quite worried because blue, powdery mould has started to grow on some of the ingredients. As far as I’m aware it has not spread to the soil but I heard that only white mould should be present in compost. Please help.

There are many molds present in compost. That does not appear to be anything dangerous, though. These molds are what are responsible for helping to break down your ingredients into soil, and will not be of much harm. Seeing this much may indicate that you need more brown (dry) ingredients, though.
