[Banana Species] Musa Basjoo - Japanese Fiber Banana

Musa basjoo is generally considered the most cold-hardy banana. While it does grow in Japan, the Japanese fiber banana is native to the Ryukyu Archipelago, which lies between Japan and Taiwan. It is also very common in parts of China. Its large, tropical foliage and fast growth rate make it ideal for a dramatic feature in the tropicalesque garden. It will eventually form a large, deep green clump, up to at least 18 feet tall.

Musa basjoo is somewhat unique in that it will actively grow in cool weather. The banana will continue growing until temperatures reach approximately 40° F. It will resist light frost, but die back at 28° F. It is is considered root-hardy to zone 6, and will survive a zone 5 winter with heavy mulch.

 Cut back leaves after soon after light frost damage occurs. Spray the root crown with a fungicide to prevent fungal rot during the winter. Use heavy mulch around the root crown to protect from freezing. Gradually remove the mulch in late winter-early spring as the risk of a hard freeze passes.

 Grow in full sun to partial shade. Musa basjoo thrives on plenty of fertilizer and water during the growing season. It will do well with a regular application of balanced liquid fertilizer applied weekly during the summer. While it is a heavy feeder, be careful not to burn the plant with too high a concentration of fertilizer. Top-dressing with composted manure is another popular feeding method. Leaves may be shredded or dried out in a windy location; pick a site with some wind protection. Source:http://coldhardytropicals.com/
