Ornamental bananas are actually very resistant. Nevertheless, the leaves can turn brown due to small maintenance errors. However, these can be quickly eradicated.Brown leaves on the ornamental banana can have different causes. The popular ornamental banana is relatively insensitive, but sometimes the leaves of the plant turn brown. There can be different reasons. Water shortage, low humidity, incorrect location or pest infestation are possible.
There is also a gratifying reason: the banana plant has offspring, so-called “Kindel”. Then older leaves simply die from the perennial. However, if the banana forms too many offspring over the years, the plant dies completely.
Cause 1: Possible maintenance errors
Occasional discoloration is normal, wait and see if it stays with individual spots.
Cut off older leaves with brown discoloration and margins, this won't harm the ornamental banana.
Not enough water:
The leaves often change color if the ornamental banana receives too little water. The leaf edges in particular look brown and dry. Water more often, but also check the substrate. The water must run off well. A permeable soil with parts of peat and coconut fibers is favorable for an optimal water supply. You can also shower the plant from time to time, but only the leaves should get wet. Low humidity sometimes also causes leaf discoloration. Regular spraying of the leaves with low-lime water or collected rainwater helps.
Too little light:
If the banana gets too little light, it tends to brown leaves. Place the perennial in a bright and sunny location, so that the condition improves again. If necessary, use a plant light. Remove the affected leaves. For healthy leaf growth, you can take precautions with regular, but economical, fertilizers. In the summer months, fertilize weekly, in winter once a month.
Pests can spread on and under the leaves. Mealybugs and spider mites are more common. In this case, the leaves turn yellow rather than brown and become soft. As a countermeasure, special oil-containing agents are useful. Choke the pests. Pest infestation usually occurs when the soil of the banana is too dry and the plant is too cool.
Cause 2: plant forms daughter plants
Small plants sprout around the stem. In this way, the ornamental banana multiplies. On the one hand, child formation is a sign that the mother plant is optimally cared for, because only healthy plants form the offspring. On the other hand: the Kindel cost strength, which is mainly shown by the browning leaves.
Carefully remove the young plantlets. If you want to grow the young plants, pay special attention to the delicate roots. Cut off the brown leaves. Older ornamental bananas, which have already had many children, will no longer be viable at some point. Then all the leaves turn yellow, then brown. Fortunately, you can grow new ornamental bananas with the young plants!
