How to Grow Bananas: A Detailed Guide to Planting Methods and Precautions

Everyone is familiar with eating bananas, but growing them is a different matter. On one hand, we lack the land to plant them; on the other hand, we lack the experience and skills to grow them. So most people are banana eaters rather than banana growers. However, bananas have stood the test of the market over a long period. Although the current market price is not very high, their stable demand is an advantage, so growing bananas should still be worthwhile.

How to Grow Bananas

1. Site selection and planting: Choose a plot with no severe frost, good air circulation and open terrain; this is ideal. Spraying a new high-fat film after planting can shorten the seedling revival period, help plants adapt quickly to the new environment and grow healthily. The amount, timing and frequency of banana fertilization must be determined according to soil fertility, yield level, growth and development patterns and fertilizer properties. Irrigation methods should suit local conditions. Irrigation should be frequent and moderate.

2. Banana cultivation techniques:

① Plant management: Removing suckers; many suckers grow in a ring around the mother plant's corm, and removing them can reduce nutrient consumption. De-budding; bananas reproduce asexually, so after the bunch emerges only the female flowers that open first at the base can be kept. The neutral flowers and male flowers that open afterward cannot set fruit, so use a small knife to cut off the upper part of the flower bud and let nutrients concentrate on fruit development. Digging out old banana corms; promptly dig out old banana corms to avoid producing a large number of large-leaf buds, which consume nutrients and make management more difficult. The wounds from de-budding and digging out banana corms should be coated with a callus anti-corrosion film to prevent invasion and infection by pests and diseases.

② Promoting the stalk and strengthening fruit: At the female flower bud stage, young fruit stage and fruit expansion stage, spray a fruit-stalk strengthening agent. This can thicken the fruit stalk, increase nutrient transport, prevent flower drop, improve pollination ability, increase fruit set rate and accelerate expansion. Because biennial bearing in the tree affects the balance of the tree's load, it affects both balanced returns and orchard tree health. Therefore, during the annual flower bud differentiation period, brush a flower-promoting agent No. 1 around the trunk to increase fruit set rate, suppress excessive shoot growth and thoroughly balance biennial bearing.

Banana Planting Methods and Precautions

1. Best propagation time: The best planting period for banana propagation is from mid-March to early April, with the specific time depending on the source of seedlings. Autumn planting is suitable from late August to mid-September.

2. Best growing soil: Banana roots are delicate and have strict soil requirements. Heavy clay soil with poor aeration and poor structure, or poor drainage, is extremely unfavorable for root development. Sandy loam with a clay content of {lj}lt;40{bf} and a groundwater level below 1 m is suitable, especially alluvial loam or humus loam;

3. Humidity requirements for growth: Bananas prefer a humid climate;

4. Best growing temperature: The growing temperature for bananas is 20-35°C, with 24-32°C being most suitable, and the minimum should not be lower than 15.5°C;

5. Best growing light: Bananas like an environment with plenty of sunlight.

6. Fertilizer application:

Bananas require a large amount of fertilizer for growth. Their root system is well developed but shallow, and especially sensitive to fertilizer. Nitrogen fertilizer can promote early flowering in bananas, with a notable yield-increasing effect. Potassium fertilizer is an essential component for synthesizing the pseudostem and leaf fibers: bananas need the most potassium fertilizer, followed by nitrogen fertilizer, and the least phosphorus fertilizer. The ratio of nitrogen, phosphorus and potassium is 4:1:14. For tall-stalk varieties, the potassium-to-nitrogen ratio is low; for short-stalk varieties, the potassium-to-nitrogen ratio is relatively high; in the early stage the potassium-to-nitrogen ratio is low, and in the later stage it is high.

7. Key watering points:

Bananas have a relatively large water requirement. Generally, monthly rainfall of more than 100 mm is required. Below 50 mm is considered a dry season, and bananas will suffer from water shortage, resulting in a prolonged bud emergence period, short fingers and low yield. Rainfall in South China is uneven; high temperatures are often accompanied by abundant rain, while low temperatures are accompanied by drought. The rapid leaf growth period is when the plant grows most vigorously and also when it needs the most water. In hot seasons, supplying sufficient nutrients and water can promote banana leaf expansion and rapid plant growth, advance bud emergence and increase yield. Long-term drought causes slow banana plant growth, yellowing, wilting and drooping leaves, and pseudostem shrinkage. During flower bud differentiation, it reduces the number of fruit hands and fruit fingers, and the fingers become shorter.

Banana Yield

Generally, bananas yield about 2000-2500 kg per mu. Good planting techniques and varieties can increase banana yield, and scientific fertilization is especially key. For example: banana grower Liang Zhenfa in Qianwu Town, Doumen District, Zhuhai, grew bananas with a fertilization cost of less than 600 yuan and achieved an average yield of nearly 6000 jin per mu, 20% higher than the provincial average yield per mu. Liang Zhenfa believes that scientific fertilization is the top priority in banana management. “Applying too much fertilizer causes waste, not only unnecessarily increasing costs, but in serious cases it can also burn the seedlings; applying too little leads to insufficient nutrition and reduced yield. Grasping the right amount is the most critical thing.”

How to Store Bananas for a Long Time

1. Many people put bananas in the refrigerator to chill them, which causes the banana flesh to turn dark brown and affects the taste. The correct method is to rinse the whole bunch of bananas several times with clean water to reduce the corrosive effect of ripening agents. Under the same external conditions, rinsed bananas can be stored 5-7 days longer without spoiling.

2. Then, use a clean cloth to wipe the surface moisture off the bananas, ensuring the peel is dry and free of moisture. Finally, wrap the bananas in a few old newspapers and place them in a cool, ventilated indoor spot.

3. Note that there is also a trick to placing bananas. If the pressure-bearing surface is too large, the banana surface in contact with the tabletop will turn black and then rot. When the whole bunch is large, it is best to let the convex side face up; when there are fewer, place them tilted on one side and eat them as soon as possible.

4. If conditions permit, it is best to hang bananas up to reduce the pressure-bearing area and extend storage time. With the above tips for storage, I believe the bananas in your home can stay “beautiful” for longer.

There should still be greater room to improve banana planting yields through technical improvements. However, banana storage has always been a very important part of banana planting management, as it not only affects banana quality but also relates to final market profits. Therefore, it is something we should all pay attention to.
