About soil condition, blue java banana tree need a loose, well-drained and fertile soil with a pH between 5.5 and 6.5. The tree will not tolerate boggy conditions. If the soil is too heavy, it can be amended with organic matter to improve drainage. Blue java banana tree is a heavy feeder and benefits from regular applications of banana fertilizer or a general-purpose fertilizer.
So, like the other banana trees, blue java banana trees need a lot of sun to grow. They should be planted in an area that gets at least 8 hours of sunlight a day. If you live in an area with hot summers, you might need to provide some shade for your blue java banana tree during the hottest part of the day.
The temperature condition that is best for a blue java banana tree is one that is warm with little to no humidity. This type of tree prefers a temperature that is between 75 and 85 degrees Fahrenheit. If the temperature gets too cold, the tree will not produce fruit. If the temperature gets too hot, the tree will produce less fruit.
Ideal humidity condition for this plant is about 60-70%. This can be achieved by regular misting or by placing the plant on a pebble tray. The plant should never be allowed to sit in water, as this will lead to root rot.
Mentioning fertilizer, usually the plant needs more nitrogen, potassium, and phosphate than other minerals. The tree's roots are very efficient in extracting these minerals from the soil. In return, the leaves of the tree provide these minerals to the soil in the form of fallen leaves.
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.
Propagation is by seed. Select a plump, ripe fruit and remove the skin to expose the pulp. Within the pulp are small black seeds. Cut the fruit in half and scoop out the seeds. 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.
Usually, the plant growth rate is about 1.5 to 2 feet (0.5 to 0.6 meters) per year. However, some exceptional cases have been recorded of blue java banana trees reaching almost 4 feet (1.2 meters) in a single year. This dependable growth rate, along with its other attributes, makes the blue java banana tree a desirable choice for many landscapers and home gardeners.
Common problems for this kind of plant are mainly due to incorrect watering, over-fertilizing, and pests. If the tree is overwatered, the leaves will turn yellow and drop off. If it's underwatered, the leaves will turn brown and dry. Over-fertilizing will burn the roots, causing the leaves to turn yellow and drop off. Pests such as aphids, mealybugs, and scale can infest the tree, causing the leaves to turn yellow and drop off.
