With the popularity of indoor green plants, Apple Calathea has been loved by many plant enthusiasts for its unique leaves and good air purification ability. During the maintenance process, many plant lovers have found that the new leaves of Apple Calathea turn green, which not only affects its appearance but may also affect its healthy growth. This article will unveil the reasons for the greenness of the new leaves of Apple Calathea and provide corresponding care techniques.
Reasons for the greenness of new Apple Calathea leaves1. Insufficient lighting
Apple Calathea is a plant that prefers semi-shade. If it is exposed to insufficient lighting for a long time, the new leaves are prone to turning green. This is because insufficient lighting prevents the plant from performing photosynthesis adequately, thus affecting the normal growth of the leaves.
2. Improper watering
Watering is a key step in maintaining Apple Calathea. If watering is excessive or insufficient, it can lead to the greening of new leaves. Excessive watering can cause waterlogging in the roots, affecting root respiration; while insufficient watering can lead to dry soil and leaf water loss.
3. Improper fertilization
Fertilization is an important means to promote plant growth. If fertilization is excessive or improper, it can lead to the greening of new Apple Calathea leaves. Over-fertilization can increase the salt concentration in the soil, affecting the plant's absorption of water and nutrients; improper fertilization can lead to a deficiency of certain essential elements in the plant.
4. Pest and disease infection
During the growth process, Apple Calathea may be invaded by pests such as aphids and red spiders. These pests absorb the nutrients of the plant, leading to leaf greening.
Apple Calathea care techniques1. Reasonable lighting
Place Apple Calathea in an environment with ample scattered light and avoid direct sunlight. If lighting is insufficient, you can move the plant to a different location or use artificial light sources to supplement the lighting.
2. Control watering
Water the plant according to the soil moisture, keeping the soil slightly moist. When watering, be careful to avoid getting the leaves wet to prevent diseases.
3. Scientific fertilization
Choose appropriate fertilizers according to the growth needs of Apple Calathea and pay attention to the concentration when fertilizing to avoid over-fertilization.
4. Prevent pests and diseases
Regularly check the growth condition of Apple Calathea and take measures promptly when pests and diseases are found. You can use insecticides or pyrethroids for control.
The reasons for the greening of new Apple Calathea leaves are diverse, including insufficient lighting, improper watering, improper fertilization, and pest and disease infections.
