Pruning your blue java banana tree is an important part of keeping it healthy and promoting new growth. You should prune your tree every few months, or as needed, to remove any dead or dying leaves and branches. When pruning, be sure to cut back to a healthy bud or branch to encourage new growth.

The Propagation

Rinse the seeds and blot them dry on a paper towel. Fill a planting pot with moistened soilless potting mix. Sow the seeds 1/2 inch deep in the potting mix. Cover the pot with plastic wrap or a humidity dome to maintain moisture. Place the pot in a warm location, such as on top of a warm furnace or water heater. Keep the potting mix moist but not soggy. When the seedlings emerge, remove the plastic and place the pot in a bright location. Gradually acclimate the young plants to outdoors conditions over a period of seven to 10 days before transplanting to the garden.
