How Do You Keep Banana Plants from Freezing

Cover the cut trunk under a mulch pile of wood chips, bark, or raked leaves as an insulating protective layer to prevent damaging freeze/thaw cycles. Apply mulch over the trunk. Spring: Remove the mulch pile and bag in the spring after the last frost and fertilize your banana to help get it jump started.

What is the lowest temperature a banana plant can tolerate?

Given their native climate, it is unsurprising that banana plants are cold intolerant. They need mild temperatures in order to grow; their leaves will stop growing at around 55°F. They will suffer leaf damage at 32°F, and their underground rhizomes will die at sustained temperatures of 22°F or lower.

When should I wrap my banana tree?

Banana plants need plenty of wrapping in winter to keep them warm. Without protection, the cold weather will decimate them and they’ll have to grow from scratch in spring. A little extra effort will ensure thriving bananas that bring tropical cheer to your garden.
