Bark mulch is a natural product from the forest that also contains microscopic spores of wood-degrading fungi. Therefore, even without the intention of growing mushrooms in the garden, mushroom growth can suddenly increase.
Take action against unwanted fungal infestation
Although some fungi that appear on bark mulch can be quite attractive in color, they are rather undesirable for many garden owners. It often helps to dig out the visible fruiting bodies of the mushrooms with a spade and bury them so that they cannot spread further via spores.
tips and tricks
If you cannot eradicate the unwanted fungi on the bark mulch in the long term, spreading lime can remove moisture and thus put an end to the fungal problem.
