What to Do When Velvet Calathea Leaves Turn Yellow, Droop and Curl? A Guide to Growing Methods

Velvet calathea (Calathea zebrina) has long, elliptical, lance-shaped leaves, with leaf surfaces in pale yellow-green or gray-green and a velvety sheen. Velvet calathea is a perennial evergreen herbaceous foliage plant of the family Marantaceae and the genus Calathea. So what are the growing methods for velvet calathea? Next, let the editor of Yiqizhuangxiu.com briefly introduce them to everyone!

What growing methods are there for velvet calathea

1. For potting soil, it is best to use well-drained leaf mold mixed evenly with 1/3 river sand, and add a small amount of bone meal at the bottom of the pot as a base fertilizer. During the peak growth period, apply a dilute liquid fertilizer with a ratio of 40% nitrogen, 30% phosphorus and 30% potassium once every half month to maintain the gloss of the leaves. Potting should not be too deep; simply plant all the roots into the soil, otherwise the growth of new shoots will be affected. In late autumn, pay attention to spraying monopotassium phosphate (0.2% to 0.3%) to benefit plant growth and improve cold resistance in winter.

2. Keep the potting soil consistently moist, but be careful not to let it become too wet, so as to avoid root rot. It has a relatively high requirement for air humidity, and it is best to keep it at around 75%. If the air is too dry, new leaves will appear curled and not unfold properly. Therefore, during the growing season, attention should be paid to frequently spraying water on the leaf surfaces and the surroundings to increase air humidity, but good ventilation should also be maintained.

3. It likes warmth, and the suitable growing temperature is 18°C to 25°C. It is not cold-tolerant, and the overwintering temperature must not be lower than 16°C. If it remains below 13°C for a long time, it will suffer cold damage. In winter, when the temperature is low, the potting soil should be kept on the dry side, otherwise the leaves are prone to scorching yellow or the roots may rot. The nighttime temperature should not be lower than 16°C.

4. Avoid strong light and exposure to the sun. The light should not be too intense, otherwise phenomena such as yellowing and curling of the leaves will occur. However, long-term insufficient light is also not acceptable, as it will prevent photosynthesis from proceeding normally and affect normal growth. In summer, shade 70%; in winter, shade 30%.

5. Repot each year in summer using a growing medium. After removing the plant from the pot, it is best to remove the soil around the roots, prune away some old roots, and add new soil for planting. If the potted plant has already grown quite large, you can move it to a pot one size larger or divide it and plant separately. After planting, water thoroughly and place it in a semi-shaded place for cultivation.

6. It is prone to leaf blight and leaf spot, and can be harmed by whiteflies, red spider mites and scale insects. Pay attention to observation and treat promptly with the appropriate remedy once discovered.

7. Propagation can be done by division. Division is best carried out in warm spring or in autumn when the temperature can remain above 18°C. First remove the plant from the pot, remove part of the old soil, divide the horizontally growing rhizomes into several clumps, with each clump having 3 to 4 small plants, and then plant them separately.

How to grow velvet calathea: growing methods for velvet calathea

Friends who love flowers and plants have all heard of velvet calathea, but many friends do not understand how to grow velvet calathea. Below, we will tell everyone the growing methods for velvet calathea.

1. Temperature: Velvet calathea likes a warm, humid environment, is not cold-tolerant, and is afraid of dryness. In winter, the growing temperature should not be lower than 10°C, while in summer the temperature should not exceed 35°C, otherwise it is extremely unfavorable to the growth of velvet calathea.

2. Watering: Velvet calathea is very sensitive to water. During the growing season, it must be watered sufficiently to keep the potting soil moist. But do not water too much; if the soil is too wet, it will cause root rot and even death. In addition, if the air humidity is low, the leaves of velvet calathea will immediately become curled. Therefore, when cultivating it, pay attention to maintaining suitable humidity, especially during high temperatures, and spray water on the leaves more often to increase air humidity.

3. Light: Velvet calathea likes a semi-shaded environment and avoids strong light and exposure to the sun. Therefore, when growing velvet calathea, the light should not be too intense, otherwise phenomena such as yellowing and curling of the leaves will occur. However, it is also not acceptable to keep velvet calathea in a completely shaded environment for a long time, as this will affect its photosynthesis and thereby affect its normal growth.

4. Fertilizing: During the vigorous growth period of velvet calathea, apply liquid fertilizer once every 1-2 weeks, and appropriately apply phosphorus fertilizer 1-2 times to maintain the gloss of the leaves. In winter, when the temperature is low, the plant grows slowly or enters dormancy, so fertilization should be stopped and watering controlled.

5. Pests and diseases: Velvet calathea is prone to leaf blight and leaf spot, and can be harmed by whiteflies, red spider mites and scale insects. When growing it, pay attention to observation and treat promptly with the appropriate remedy once discovered.

6. Repotting: When growing velvet calathea in pots, repot it every year in May. The main task is to prune away some old roots and add new soil for planting. If the plant is relatively large, you can move it to a pot one size larger or divide it and plant separately. After planting, water thoroughly and place it in a semi-shaded place for cultivation. For potting soil, it is best to use well-drained leaf mold mixed evenly with 1/3 river sand, and add a small amount of bone meal at the bottom of the pot as a base fertilizer. Avoid using heavy clay soil for potting. The potting depth should be such that the roots are not exposed.

7. Propagation: Velvet calathea is mainly propagated by division. The best time for division is in early spring (February, March) after the soil thaws. The divisions should not be too small, so as not to affect the growth of the new plants. After the new plants are potted, water should be controlled, and they should be kept in a semi-shaded place for care. Only after new roots have emerged can they be watered fully.

II. What to do when velvet calathea leaves turn yellow

1. Temperature: Velvet calathea likes a warm and humid environment, and the suitable growing temperature is 20-28°C. If the temperature is too high or the air is too dry, the leaves of velvet calathea will curl, shrivel and scorch at the edges. Therefore, let it grow at a suitable temperature.

2. Sunlight: Velvet calathea is a shade-loving plant, so when growing it, pay attention to shading and avoid exposure to strong sunlight. If exposed to direct sunlight, the leaves of velvet calathea will be scorched, causing localized scorching at the leaf edges, stopping the growth of new leaves, and yellowing of the leaf color.

3. Diseases: If velvet calathea is kept for a long time in a high-temperature, humid environment with poor ventilation, the plant will become weaker in growth and prone to leaf blight. It generally infects from the leaf edges and leaf tips, with lesions developing from small to large in irregular shapes, ranging from reddish brown to grayish brown, and plants are more severely affected on the lower leaves. The main pests and diseases are leaf spot and leaf blight, which can be controlled by spraying lime Bordeaux mixture. For pest damage, there is whitefly, which can be killed by spraying with 25% phosmet emulsifiable concentrate at 1000 times dilution.
