If the duck palm wood is only the bottom of the plant with sporadic yellow leaves, this is also a natural phenomenon of degradation, you can directly remove the yellow leaves can be. When there is a large area of yellow leaves, leaf drop, we need to find out the cause of leaf drop, so that we can solve the problem in a timely manner.
One, watering too hard to lead to long-term wet potting
Duck feet wood is like warm and moist plants, in the maintenance process need to ensure that there is enough water, in order to make the plant grow vigorously. But give it too hard watering is also easy to get out of the problem, if you do not wait for the potting soil dry water, long-term make the soil in too wet state, it is easy to make the root system suffocation, and finally rot, resulting in yellow leaves and leaves.
Solution
Watering should be dry and wet, do not make the potting soil is too wet for a long time or there is stagnant water, to keep a little moist can be. If too much watering caused by rotten roots, we should promptly take off the pot, prune the rotting root system, and use 0.2% potassium permanganate solution or polymyxin to sterilize and disinfect the treatment, and then re-potting. At the same time, prune off the yellowing branches and leaves to reduce nutrient consumption.
Additionally, when potting duckweed, it is also necessary to pad a good drainage layer, and try to use a well-drained and breathable culture soil, so that excess water can be discharged smoothly, to prevent the roots from rotting due to stagnant water.
Two, too much fertilizer caused by burning roots
In the home of the flowers and plants fertilizer, try to do thin fertilizer, especially the use of chemical fertilizers, if you do not grasp the amount of fertilizer, it is easy to burn the root system, a large number of yellow leaves, leaf drop phenomenon.
Solution
If the fertilizer is too thick caused by burning roots, we should immediately pour a few more times of water, so that the water in the basin from the drainage holes out of the water, after a few times of large water irrigation can dilute the concentration of certain fertilizers, to reduce the damage caused by the root system.
We usually fertilize as much as possible to do thin fertilizer multiple times, the use of organic fertilizers, be sure to go through sufficiently ripe and fermented in advance before applying to the pot, otherwise it is also easy to burn the roots of the yellow leaves.
Three, too much light can easily cause yellow leaves
The duck's foot wood is like a semi-shade environment plants, afraid of strong light direct sunlight, usually as long as it is placed in the diffused light can meet the growth requirements. If you don't pay attention to the shade in the summer, directly exposed to the sun, it is easy to sunburn leaves, resulting in branches and leaves withered and yellowed off.
Solution
The duck's-foot tree should be avoided strong light, occasionally let it sunshine scattered light can make the plant grow vigorously. Keep it in a cool and ventilated place in summer when the light intensity is high to prevent sunburn.
When yellow leaves appear to fall, immediately prune off the yellowed branches and leaves, and transfer the potted plant to a light ventilated place to maintain.
The duck's foot wood has limited cold tolerance, winter to move it to warm indoor care, the environment is too dry, but also often to the plant spray water to increase the humidity of the environment, in order to facilitate the growth and development of the plant.
