Why is there mould on my bark chip mulch? How do you get rid of it?
When I turn it over, the mould has a creamy yellow appearance.
The white mould appearing on your bark chips is a sign that your mulch is beginning to break down. This fungus plays a part in the natural decomposing process of wood and is not detrimental to plants. If you are concerned, you may wish to turn your mulch over regularly to slow down the fungus or apply a new layer.
