What to Do When Calathea (Cat's Eye) Leaves Turn Yellow? Causes and Solutions

Growing Techniques Jan 1, 1970 0 views

Improper Lighting: Calathea (Cat's Eye) prefers shade. Too much light can scorch the leaves, causing yellow spots on the leaf surface, which leads to the leaves drying out and turning yellow. In this case, move the Calathea to a shaded spot indoors. If there is too little light, the leaves cannot receive sufficient sunlight and cannot form chlorophyll.

Calathea (Cat's Eye) prefers shade. Too much light can scorch the leaves, causing yellow spots on the leaf surface, which leads to the leaves drying out and turning yellow. In this case, move the Calathea to a shaded spot indoors.

If there is too little light, the leaves cannot receive sufficient sunlight and cannot form chlorophyll, causing the leaves to turn yellow and drop. In this case, supplemental sunlight is needed.

Improper Watering

Calathea (Cat's Eye) has relatively large leaves and water evaporates quickly. If the old leaves begin to scorch yellow and drop, and the leaf tips and edges dry out and curl, it means the Calathea is being underwatered. Water more, mist more, and keep the potting soil and surrounding air moist.

When the young leaves of Calathea (Cat's Eye) are dull and lackluster, and the stems and new shoots are shrunken, small, and yellow-green, it is very likely caused by overwatering. At this point, place the Calathea in a ventilated area, dry out the root ball, and reduce watering frequency. Water less but water thoroughly.

Improper Fertilizing

During the growing process of Calathea (Cat's Eye), if the leaf tips of new leaves turn yellow-brown and the old leaves scorch yellow and drop, it is because the fertilizer concentration is too high, causing the plant to turn yellow. Stop fertilizing immediately. In severe cases, replace the potting soil and rinse off the fertilizer residue on the roots and leaf surfaces of the Calathea.

If fertilizer is rarely or never applied, yellowing leaves may also be due to a lack of nutrients. Repot in a timely manner and apply light fertilizer frequently.

Now that we understand the causes of yellowing leaves in Calathea (Cat's Eye) and how to handle them, let's look at winter care tips for Calathea (Cat's Eye)! Winter care for Calathea (Cat's Eye) is very important.

What to Do When Calathea (Cat's Eye) Leaves Turn Yellow: Solutions for Leaf Spot Disease in Calathea (Cat's Eye)

Calathea (Cat's Eye) is the most common perennial evergreen herbaceous plant and is often grown indoors. It is a relatively easy plant to grow. But even the easiest plants to grow can experience various problems. What to do when Calathea (Cat's Eye) leaves turn yellow? What are the solutions for leaf spot disease in Calathea (Cat's Eye)? Let's take a look together.

What to Do When Calathea (Cat's Eye) Leaves Turn Yellow?

1. Too Much Light

Strong direct sunlight hitting the shade-loving Calathea (Cat's Eye) easily causes the leaf tips and leaf margins to dry out, with yellow spots appearing on the sun-facing parts of the leaves. Simply move the Calathea to a shaded area.

2. Lack of Light

If Calathea (Cat's Eye) is placed in a shaded environment for a long time, the leaves cannot receive enough sunlight and cannot form chlorophyll, causing the leaves to turn yellow and then drop. Supplemental lighting can prevent the leaves from turning yellow.

3. Overwatering

If the young leaves of Calathea (Cat's Eye) are dark yellow and lackluster, while the old leaves show no obvious change, and the stems are thin and yellow-green with new shoots shrinking and not growing, it indicates that the Calathea is being overwatered. Remove the Calathea from its pot and place it in a ventilated, shaded area. After the root ball dries, put it back in the pot.

4. Underwatering

If the leaf tips or edges of Calathea (Cat's Eye) dry out and become parched, and the old leaves wither yellow and drop from the bottom up, but the new leaves are growing relatively normally, it indicates that the Calathea is being underwatered. Simply water thoroughly and generously.

5. Too Much or Too Concentrated Fertilizer

Applying too much fertilizer or fertilizer that is too concentrated can cause yellowing leaves. This manifests as dry brown tips on the new leaves of Calathea (Cat's Eye). Generally, the leaf surface is thick and lackluster, uneven and not smooth, and the old leaves scorch yellow and drop. Stop fertilizing immediately. In severe cases, use a large amount of water to flush out some of the fertilizer from the Calathea.

6. Too Little Fertilizer

If the young leaves of Calathea (Cat's Eye) become pale, yellow, or light green, while the old leaves remain relatively normal or gradually turn from green to yellow, it may be caused by insufficient fertilizing. Check the potting soil of the Calathea. If there is hardening, replace the soil. Regularly apply light fertilizer frequently and occasionally water with alum water. Apply fertilizer primarily based on nitrogen fertilizer to the Calathea.

Solutions for Leaf Spot Disease in Calathea (Cat's Eye):

The leaf spot disease of Calathea (Cat's Eye) produces yellow-brown lesions. In the early stages, small yellow spots form near the leaf margins or in the center of the leaves, and gradually expand and darken, turning yellow-brown. There is a relatively obvious halo around the lesions. As the lesions spread, the leaves of the Calathea gradually dry out, wither, and eventually drop off and die. The causes of leaf spot disease in Calathea (Cat's Eye) are high temperature and high humidity, poor air circulation, placing Calatheas too close together, excessive weeds and rotting leaves in the growing environment, excessive nitrogen fertilizer application, and leggy growth of the Calathea.

Promptly remove diseased and dead leaves as well as weeds to reduce sources of infection. Calatheas should not be placed too close together. Proper ventilation and light transmission, and reducing environmental humidity, can reduce the incidence of disease. When disease occurs, spray for protection: 50% carbendazim at 600x to 800x dilution, or 75% chlorothalonil at 600x to 800x dilution, or 50% mancozeb at 500x to 600x dilution, once every 7 to 10 days. Alternate the use of various chemicals to prevent the leaf spot pathogen from developing resistance. Normally strengthen fertilizer and water management, appropriately increase phosphorus and potassium fertilizer, reduce nitrogen fertilizer, and promote sturdy growth of the Calathea to enhance its own resistance.
