The banana on the slope of the bank of the Fengyuqiao River has been delicate recently, attracting many tourists to stop and watch. While appreciating the stunning beauty of the banana, people also suddenly discovered the "failure" of the existence of the banana ~ the base leaves are yellow and scorched.

Why didn't anyone come to fertilize the bananas? The leaves of the feet were so yellow that they were almost gone. This is probably not due to a lack of fertilizer, or because of waterlogging! In the face of the yellowing of the "foot leaves" of the withered bananas, people are gossiping and exploring the reasons for the yellowing of the dead leaves of the red bananas.
Zhujiao is also known as palm bamboo, iron red tree. As a common foliage appreciation greening plant, with its unique leaf form and bright color, it has won the favor of many plant lovers and tourists.
In the "Notes on South Vietnam", the origin of the name Zhu Jiao is described in detail. "Zhu banana, leaf plantain and dry palm bamboo, also known as Zhu bamboo. The branches are not very straight, so they think they are bananas. The leaves are purple and grow on the stem. The stem is knotted, from root to tip. One inch three or four knots, or six or seven knots. Very dense. However, there are many people who come out alone, and there are no double branches".

From the expression in the text, we can see that the banana is mostly an independent plant, and the stem nodes are very short, similar to the stem of the palm tree.
However, in the process of planting and maintenance, sometimes the leaves at the base of the banana are "yellowed" and scorched, which not only affects the aesthetics of the plant, but also may cause potential harm to the healthy growth and development of the plant.
So, why do the leaves of the banana appear scorched, and what are the good ways to correct this problem?
In this issue, Qingjiang Crane will continue to pay attention to and chat with all the teachers about the related topics of banana planting, aiming to discuss from the aspects of cause analysis and correction methods, so as to improve the effect of people planting banana. I hope you like and actively participate in the interactive comments, forward and share the pictures and texts of this issue.

Analysis of the reasons for the scorching of the basal leaves of the banana during the planting process:
01) Scorching phenomenon of leaves at the base of banana caused by too strong light:
Although the banana likes a sunny environment for growth and development, it is exposed to strong sunlight for a long time, especially in the high temperature period of spring, summer or summer, which can easily lead to burns of the leaves at the base of the banana, and then scorch.

02) Scorching phenomenon of basal leaves caused by insufficient water:
If there is a lack of water for a long time or uneven watering (local water), it will cause the leaves to dry up due to insufficient water, or even scorched.
Local water accumulation, if not drained for a long time, the root system of Zhujiao is in the "high groundwater level" for a long time, and the root system is affected by lack of oxygen respiration. There are few or no new roots, and the root system cannot absorb water and nutrients from the soil, resulting in the vegetative growth and development parts of the banana, and the above-ground plants will appear yellow due to uneven or no nutrient moisture, and the basal leaves will be yellowed due to uneven or no nutrient water, and scorched when seriously harmed.

03) Yellow and scorched leaves at the base of banana caused by low air humidity:
If the environment is too dry, the leaves are easy to lose moisture, and then scorch. Especially for indoor potted bananas, if no one has watered them for a long time, or the indoor air humidity is not enough, the basal leaves will be burnt yellow.
04) Yellowing and scorching of the leaves at the base of the banana caused by improper use of fertilizer:
Excessive fertilization (use of fertilizer beyond the standard concentration) or application of inappropriate fertilizer or improper fertilization method (fertilizer damage) will cause scorching of banana leaves.

Too much salt in a fertilizer or an imbalance in nutrients can cause damage to the leaves.
05) Yellowing and scorching of the basal leaves of the banana caused by the replacement of the new:
The basal leaves are always gradually withered and scorched from the lower basal leaves upwards in the "new and old" replacement, which is a natural physiological phenomenon.
Scorch correction method of banana leaves:

01) Adjust the light conditions between plants.
For scorched leaves caused by too much light, you can move the banana to a semi-shaded place (potted banana) to avoid prolonged exposure to strong sunlight. Immovable bananas, such as those on the slopes of river banks, can be watered in the morning or evening to "cool down" during the hot season. Of course, shade nets can also be supported to reduce the "exposure" of bananas, but affect their ornamentation.
At the same time, potted bananas can also be shaded during the high summer period, such as building shade nets or using parasols or moving to a cool place to reduce the light intensity.

02) Watering reasonably, "let me drink enough at once":
Maintaining an adequate water supply is the key to preventing leaf scorching. Indirectly, it means ensuring good soil moisture.
When watering potted bananas, it is necessary to pay attention to even watering to avoid local water shortage. Do not pour "half water", if you want to water, you should water it thoroughly at one time. Bananas grown in the open field also need to be replenished with nutrients and water in time when the soil is dry. At the same time, the frequency of watering should be adjusted according to the season and weather conditions to ensure that the water needs of the plants are met.

03) Increase air humidity to create a good and comfortable environment.
To increase the humidity of the air, you can place some water basins or humidifiers around the potted bananas to increase the moisture content in the environment. In the case of extremely poor water and fertilizer retention performance of loam, the plantain planted in the open field should be supplemented with nutrients and water according to the change of moisture, "eat less and eat more", otherwise, the yellow leaves at the base of the banana will not be "corrected".
In addition, regular spraying of water on the leaves of the plant is also an effective way to increase the humidity of the air.
04) Scientific fertilization to ensure sufficient nutrient supply for the growth and development of banana.
When fertilizing, choose a fertilizer suitable for the growth and development of bananas, and fertilize according to the recommended dosage on the instructions.

Avoid over-fertilizing or applying unsuitable fertilizers to avoid damage to the leaves. At the same time, it is necessary to pay attention to the regular replacement of the soil (repotting) to maintain the balance of soil fertility and the appropriate pH of the loam. Planting enthusiasts with conditions can choose a special substrate seedbed fertilizer to mix the culture soil and adjust the pH of the loam.
During the vegetative growth and development period of the banana, combined with foliar water spraying or comprehensive pest control, an appropriate amount of multi-functional foliar fertilizer with high potassium can be sprayed to make the flower color of the banana more beautiful. For example, crystalline potassium dihydrogen phosphate, amino acids or humic acid multifunctional foliar fertilizers, etc. These foliar fertilizers are sold in many categories in the agricultural materials market, and they can be purchased and selected purposefully according to their own production needs.

Words written at the end:
Scorched leaves are a common maintenance problem, but as long as the correct cause analysis and correction methods are mastered, this problem can be effectively solved. By adjusting light conditions, watering reasonably, increasing air humidity and fertilizing scientifically, we can rejuvenate the banana and show its unique charm. As plant lovers, we should continue to learn and explore to provide a more suitable growth environment for ornamental plants such as bananas.
