The reason for the loss of leaves in the latest banyan bonsai
Banyan bonsai is a common ornamental plant in daily life. Flower friends who cultivate banyan bonsai often encounter it with falling leaves, normal falling leaves are old leaves to grow new leaves, and some abnormal falling leaves are the reasons why daily maintenance is not well maintained. let's take a look at the reasons and solutions for the loss of leaves in banyan bonsai.
Improper watering causes loss of leaves
Banyan watering must adhere to the principle of not drying and watering thoroughly. Drying here means that the surface of the basin soil is dry, not thoroughly. Of course, even if it is dry, it will not cause great harm to the banyan tree in a short time, because the leaves of the banyan tree are thick and small, and have a certain degree of drought tolerance.
Improper fertilization causes loss of leaves
The fertilization of banyan tree needs to be carried out by applying thin fertilizer frequently to avoid the application of high concentration chemical fertilizer or unfermented mature organic fertilizer, otherwise it will cause fertilizer damage, the light ones will lose their leaves and the heavy ones will die.
Lack of light causes loss of leaves
The banyan tree grows well in the environment with sufficient light, and the leaf color is greener if it can shade 30-50% of the sun in summer, but it is best not to shade the sun when the temperature is lower than 32 ℃, so as not to lose the leaves.
Loss of leaves caused by insect pests
The main pests that lead to defoliation of banyan trees are red spiders and shell insects, although there are also "thrips". This kind of insect only rolls leaves to absorb juice, which is less harmful than the above two kinds, and thrips are easy to control and can only be removed and destroyed. The individual red spider is relatively small, and the general harmful part is the back of the leaf, which is caused by poor ventilation and dry air. The whole plant can be washed with water and sprayed with special mites, such as mites, acaroid mites and so on. The harmful parts of shell insects are mainly stems and petioles, with different size and color, round and oval in shape, and generally do not move, but they are harmful and need to be prevented and treated in time. They can be wiped clean with a toothbrush or dishcloth, or 0.2% solution of detergent and essential oil can be sprayed, or pesticides such as methamphetamidophos are sprayed with good results.
The solution to the loss of leaves in banyan trees
1, within four weeks, to less watering, usually only keep the cultivation substrate 5 or 60% wet on the line. Too much water will increase the chances of wound decay in the roots. The drier substrate is beneficial to the growth of new roots.
2. Shade 50% to 70%, or keep it in a semi-shaded environment for three to four weeks. Too strong light will increase transpiration.
3. Spray more foliar water to maintain high air humidity and moist leaves in the small environment, which can reduce the temperature of leaves, reduce leaf transpiration and reduce the loss of water.
4. Ginseng banyan is native to the south and likes slightly acidic water and soil. Peat soil is recommended to be used in the cultivation medium, and the water used for irrigation also needs to be softened. Soaking in a bucket of water for 24 hours after wrapped with a jin of activated carbon or peat soil gauze can reduce the pH of the water.
5. without considering fertilization within four weeks, there is a large amount of water and nutrients in the ginseng banyan body for it to consume for a period of time. Fertilize the root before the wound is fully healed. Not only can the root not absorb it, too much fertilizer will force the water from the root cell to flow back into the substrate. Four weeks later, it is recommended to use the nutrient solution sold in the flower market.
