Upon finding the strange fungus mould like mounds that seemingly sprouted up in every corner of the garden growing like they were bubbling up from below the surface, I honestly didn't know what to make of them. How did they get here? Are they bad for the garden? How do I remove them?
Do I remove them. I sprayed them with the hose to try and wash them away, but found out they were impermeable to water. I kicked one and it turned into a black cloud of smoke (releasing its spores everywhere, not a smart move).
Mould in the mulch
After putting on my gloves, I removed each of the mounds as they seemed to have only inhabited the top centimetre of the wood chips. After consulting my team, we found out the fungus was not a Spadina orientated problem. The fungus had indeed surfaced in other LEAF gardens in the city.
Close up of mould
We are now in the midst of testing a removal and mitigation tactic. Removing and disposing of the fungus, and using two small doses of apple vinegar applied to the site to attempt to destroy any remaining spores. Check back for updates on our progress!
