How to maintain the yellowing leaves of small coconut trees

The adaptability of small coconut trees is relatively strong, but if they are too lazy or improperly operated in the process of breeding, they will still cause their leaves to yellow and other phenomena.

The cultivation method of small coconut tree

1, growth habits: like warm, humid and semi-cloudy environment. The suitable temperature for growth is 20~30 ℃, and it enters dormant period when it is 13 ℃. The lowest temperature for winter overwintering is 3 ℃.

2, pot soil: small coconut tree potted generally available rotten leaf peat soil plus 1/4 river sand and a small amount of base fertilizer culture for the substrate. It is best to plant on well-drained, loose, fertile loam.

3, watering: follow the method of wet rather than dry, so that the soil to maintain a long-term wet state. In hot, dry conditions in summer, it is necessary to spray water frequently to increase the humidity of the surrounding air and make the leaves evergreen; in winter, water should be reduced to better survive the cold winter.

4, fertilization: growth period can be applied 1-2 times a month liquid fertilizer, organic fertilizer or three elements can be. From late autumn to winter, fertilizer is applied thinly, and no fertilizer is needed after entering the dormant period.

5, sunshine: suitable for growth in a semi-shady environment, high temperature weather pay attention to proper shade, leave 50-60% of the light, must not accept direct light, otherwise it will make the leaves fade or even yellow, cause scorched leaves and black spots, affecting the aesthetics.

6, temperature: suitable temperature for growth is 15-30℃, which is 19-30℃ in May-September, 13-16℃ in October-April of the following year, in summer, it can withstand high temperature of 35℃, when the temperature exceeds 35℃, it should be properly shaded or sprayed with water, ventilation and other measures. In winter, the ambient temperature should be maintained at not less than 5 ℃, otherwise, it is easy to freeze and fall.

7, pests and diseases: small coconut trees in high temperature and high humidity, easy to occur brown spot disease. If brown spot disease is found, 800-1000 times of thiophanate or baishengling should be used in time to control it. In dry air, poor ventilation is also prone to scale insects. If scale insects are found, artificial scraping can be used, and 800-1000 times omethoate can be sprayed for control.

Small coconut leaves yellow cause

Too little watering: small coconut trees like moisture, need enough water, if too little watering will yellow leaves and gradually wither off. Solution: often watering to keep the pot soil moist, summer and autumn air dry, often spray water to the plants to improve the air humidity of the environment.

Fertilization too thick: small coconut tree fertilizer requirements are not high, if too much fertilizer will occur fertilizer damage, resulting in yellow leaves of small coconut trees. Solution: Small coconut tree growth season 1-2 times a month liquid fertilizer, late autumn and winter a little fertilizer or no fertilizer.

Light too strong: small coconut trees like semi-shade conditions, light too strong when the small coconut leaves will become pale or yellow, lose ornamental value. Solution: Maintain the small coconut tree in a place with sufficient astigmatism, which can provide enough light for growth and will not cause yellowing of the leaves caused by excessive light.

Disease infection: In high temperature season, small coconut trees are easily infected by root rot, etc. Disease infection will lead to yellow and withered leaves of small coconut trees, and serious cases will cause plant death. Solution: Pay attention to the ventilation of the growing environment of small coconut trees and the permeability of the soil. When the disease occurs, topozine and chlorothalonil can be sprayed.

Small coconut tree type beautiful and generous, bright green leaves, placed in the room can almost match each other with various styles of furniture, play a role in beautifying the room, so it is very suitable for home farming.
