I was going through my (eek! seriously disorganized) photo files yesterday and I came across these two pics that I took at the community garden this fall. The light was absolutely amazing that day in October.
Although they look pretty, the mushrooms are symptomatic of a problem in the community garden. Large chunks of wood mulch were used to dress the beds along the perimeter fence when the garden was built about five years ago (and by “large,” I mean HUGE – see Exhibit A, above). It was all done mainly for aesthetics over any practical purpose and through the years, many of the chips have been dug under, creating a soil structure akin to cement. Pore space is at a definite premium, and will eventually affect the way crops grow. (I won’t get into the whole carbon-nitrogen imbalance thing here, but that’s an additional issue. I recently read that bark chips can take at least a decade to decompose in soil). To make matters worse, this year, the mushrooms turned up in full force. LOTS of mushrooms. Expected, sure, but definitely not welcome. Although we made an attempt at damage control in the fall and removed some of the uppermost layers of the wood chip/soil clumps, we’ve got a long way to go to fix this mess. Definitely a cautionary tale about using the right mulch for the job (and in this case, about not digging it in)!
Let’s talk soil and/or mulch – do you have any problem areas in your garden?
