Lots of pecan shells
This year there's a good crop of shells, even if a lot of the nuts aren't fully formed due to drought. AND I'm doing a lot more baking so am not extending my usual invitation to people to "come and get 'em." So I've got a LOT, probably the equivalent of 2 lawn-size garbage bags, possibly 3 if they are many more yet to fall.
I've already put some in my compost, as per usual, but am becoming concerned about the proportion of shells to the other stuff. Is the juglone gone when the shells are no longer recognizable? Is there a set amount of time for the juglone from pecan shells to dissipate, or does it "depend on...?" Is there a substance known to negate juglone when composting? Should I make a separate pile to be left alone longer than usual?
