What will kill banana trees?
Accordingly, how do you stop banana trees from spreading?
It should be easy to reach the roots, as they tend to be quite shallow in banana plants. Sometimes the extensive root system, which can reach 18 feet long, becomes invasive to other plants. Cut these roots close to the plant itself to shorten and detach them, reducing their spread.
Also to know is, how deep are the roots of a banana tree?
The rhizome, suckers and their fibrous roots form a mass of roots known as the mat. In well-drained, loose soils, the roots can reach up to 5 feet deep and spread up to 30 feet horizontally.
Well-Known Member. Are banana trees considered an invasive plant in certain areas. I have been growing them for several years in Virginia and they multiply quite dramaticly and survive our cold winters with no winter protection, I don't even cut them back anymore until the next spring.
