Similarly, what is the best fertilizer for banana trees?
A banana plant's rapid growth rate makes it a heavy feeder. Young plants may need as much as ¼ to ½ pound of fertilizer per month. A balanced fertilizer of 8-10-8 (NPK) is recommended.
Herein, how often do you fertilize banana trees?
During the summer,fertilize your Banana Trees once a month with a well-balanced organic fertilizer. Formula 10-10-10 is an excellent choice. After your banana harvest, cut your tree back to about 30 inches and let the stem dry out for two weeks before removing it.
When fertilizing a mature banana plant, use 1 ½ pounds of 8-10-10 per month; for dwarf indoor plants, use half that amount. Dig this amount in around the plant and allow it to dissolve each time the plant is watered. Or you can give the banana a lighter application of fertilizer each time it is watered.
