Mushrooms spread mainly through their spores, released into the air and able to travel long distances. To prevent sprouting in your garden, reduce shade with proper tree pruning and test soil for pH levels. Use compost instead of mulch, and add nitrogen-rich fertilizers to promote plant growth and decay organic matter so fungi can’t take hold. Identify mushroom species correctly before attempting removal, as some may be poisonous if ingested. With these steps, you’ll have a better chance of avoiding a fungus infestation in your garden!
