Composted leaf litter:Allow natural leaf litter to accumulate around the growth area to provide ongoing nutrient sources
Pruning
  • Remove mature fruiting bodies after spore dispersal to reduce lingering foul odor
  • Avoid disturbing the underground mycelial network, as it supports future fruiting cycles
  • Clear excess debris only if it blocks air circulation around the growth site
