Winter Care for Large In-Ground Banana in Tennessee (Zone 7)

Mulch the Corm Deeply

After first frost kills the top, cut pseudostems to ground. Cover the crown with 12–18″ of loose mulch (straw, leaves). The corm survives if soil doesn't freeze solid.

Spring Uncovering

Pull mulch back gradually as new shoots emerge (usually April). Fertilize with high-K fertilizer once growing actively.
