We are gearing up towards winter here in N. IL....which partly means whacking the peony plants to the ground and burning the stalks/leaves (cannot compost them). Unfortunately, I planted new blueberry bushes on either end of the peony bed. Yeah...well.... The blueberry bushes are now 4" tall. They are a bush type to begin with...so I'm thinking they'll survive. Any 'whoops, us too?!' comments? Should I mulch heavily to protect the cut ends?
