What kind of plant is the cast iron plant? An analysis of the causes of yellowing leaves
What kind of plant is the cast iron plant? The cast iron plant (Aspidistra elatior) is a plant native to the south, able to adapt to warm, humid and shady environments, and able to survive in infertile soil, but it is not very cold-resistant. Many people have encountered the phenomenon of cast iron plant leaves turning yellow, and do not know what causes the leaves of the cast iron plant to turn yellow?
1. Too little light
[Cause] The cast iron plant is extremely shade-tolerant, and can even be displayed in a dark room for several months, but being too dark for a long time is not conducive to the sprouting and growth of new leaves. If it is kept in a dark place with too little light for a long time, the leaves of the cast iron plant will turn yellow.
[Method] If the cast iron plant is placed in a dark room, it is best to move it every so often to a place with bright light for a period of care, to benefit growth and display, especially during the period from the sprouting of new leaves to the maturity of new leaf growth, when it must not be placed in too dark a place.
2. Too concentrated fertilizer
[Cause] The cast iron plant does not have a particularly large demand for fertilizer, and it is best to apply only a light fertilizer each time. If too much fertilizer is applied, it will burn the roots, disrupt the growth of the cast iron plant, and the leaves will turn yellow due to fertilizer damage.
[Method] Apply a thin liquid fertilizer 1-2 times a month to promote the sprouting of new leaves and robust growth, and to keep the leaves fresh and bright. Do not apply too much fertilizer.
3. Too intense light
[Cause] The cast iron plant dislikes direct sunlight, and even a short period of exposure to strong sunlight may cause leaf scorch and yellowing, reducing its ornamental value.
[Method] The cast iron plant can be grown year-round in a bright room, but whether indoors or outdoors, it must not be placed in direct sunlight.
4. Pest infestation
[Cause] Cast iron plants cared for indoors are very prone to red spider mites, and the appearance of pests is also a cause of the leaves of the cast iron plant turning yellow.
[Method] Frequently check both sides of the leaves, and promptly spray dicofol, hexythiazox and the like for control.
5. Too much watering
[Cause] Too much watering is also one of the causes of the leaves of the cast iron plant turning yellow. The cast iron plant likes water and has a certain tolerance; even after several days of drought it will not die, but if watered too much it will affect root respiration and thus cause the leaves to turn yellow.
[Method] Water the cast iron plant by the principle of watering when dry and stopping when wet; do not water too much, but not too little either. During the growth period it needs sufficient water.
Post-harvest management: potted cast iron plants that have left the nursery can be stored in a bright place with a relative humidity of 90%-95%, an ambient temperature of 10-15°C, and no direct sunlight. Do not make the ambient air too ventilated. On the premise of ensuring product quality, the storage time should not exceed 3 weeks, and watering should be stopped 2-3 days before transport.
