Gardening

Offgassing from fruits and vegetables, molds, rot... nuh-uh.

Put it in a cardboard box and sift slightly damp potting mixture over it until it's covered; don't pack it in. If the potting mixture doesn't have much vermiculite or perlite in it, mix in some shredded newsprint or other aerating material.

Put it in a dark, consistently cool (40-45 degrees fahrenheit) place. Mist the potting mixture now and then so it doesn't dry out altogether.

Next spring after the ground becomes workable, plant it in a place where it will not be waterlogged. Mark it with a good sturdy stake. It will probably not do much next year-- might not even sprout, but don't give up on it. Year after, year after that, it should take hold and give you lovely peonies.

helpfully,
