Causes of and Solutions for Scorched and Curled Edges on Peacock Plant Leaves

The peacock plant (Calathea makoyana) has relatively large leaves, most commonly green, with light green stripes on the upper surface that make it very distinctive. It is now a fairly popular houseplant, but many people, because they do not understand it during the process of growing it, end up with problems such as scorched leaf edges and curled edges.

Causes of scorched leaf edges on the peacock plant

Generally, when the peacock plant develops shrunken leaves, it is caused by inappropriate temperature and humidity. The peacock plant likes a high-temperature and high-humidity growing environment. During care, if the temperature is too low, scorched edges will appear.

2. The next cause is insufficient humidity. The peacock plant itself likes moisture, and both the potting soil and the air should be kept at relatively high humidity. But when watering is too little, the insufficient water cannot meet the growth needs of the peacock plant, and it is bound to develop shrunken leaves.

3. Water accumulating in the pot is also a cause. The peacock plant likes moisture, but if water accumulates in the pot, it will cause root rot, and the leaves will curl and develop scorched edges.

Solutions for scorched leaf edges on the peacock plant

When the peacock plant develops scorched leaf edges, the first thing to ensure is reasonable temperature and humidity. The temperature should be kept above 18°C, and daily water and fertilizer management should be done well, taking care that no water accumulates in the pot. In addition, except when it is raining, you can also spray water on the plant to raise the air humidity. If the shrinking of the peacock plant is relatively severe, you can cover the plant with a plastic bag and tie it tightly with string, leaving a few small gaps, which can retain moisture and help the leaves recover.

What to do when the peacock plant's leaves curl

1. Unsuitable ambient temperature and humidity.

Symptoms: When the peacock plant is in a stuffy, hot environment, the plant grows poorly, and the leaves gradually curl instead of stretching out freely. If no measures are taken, over time the leaves and roots will rot, and it may even wither and die.

Solution: Strengthen daily water and fertilizer management, ensure the plant has sufficient nutrients, and enhance its disease resistance. If the plant is placed in an enclosed indoor environment, besides on rainy days, spray it every day to increase humidity, at least 3 times a day. If the leaves are especially severely shrunken, you can cover the entire plant with a plastic bag and poke some small holes at the pot opening, which can both maintain a certain humidity and provide appropriate ventilation to aid recovery.

2. Too little watering, humidity too low.

Symptoms: The peacock plant likes a relatively moist environment. If the watering method is wrong and the water has not soaked through for a long time, the inside of the soil will gradually compact, which cannot be seen from the outside, but as time goes on, the leaves will gradually curl, accompanied by some dead parts and yellowing of the lower leaves.

Solution: The peacock plant originates from the tropical rainforests of South America and requires relatively moist growing conditions. Besides keeping the potting soil moist and not waiting until the potting soil dries out before watering, as long as there is no water accumulation and root rot, you should also maintain relatively high air humidity in the surrounding environment. Therefore, in summer the plant should be placed in a semi-shaded location, and water should be sprayed on the leaves 2~3 times a day to increase humidity and lower temperature, promoting robust growth of the plant.

What to do if the peacock plant does not grow tall

1. Unsuitable temperature, too high or too low, or insufficient light. As far as the habits of the peacock plant are concerned, it likes a warm, humid, and shady environment, does not like low temperatures or windy conditions, and especially must not be exposed to direct sunlight. Therefore, in the hot summer season, the plant should be moved to a shady place. In addition, be sure to avoid a high-temperature environment, keep the ambient temperature below 30°C, and frequently spray water and ventilate to lower the temperature and preserve moisture, so as to avoid situations such as yellowing leaves. Of course, in winter, light should be appropriately increased and the temperature raised.

2. Insufficient nutrient supply in the potting soil, because the peacock plant likes fertile, loose soil with good drainage, preferably slightly acidic leaf mold, or a potting mix made by mixing decomposed base fertilizer, leaf mold, peat, and river sand.

3. Insufficient water supply. As mentioned earlier, the peacock plant likes moisture, and especially during its growing season it has a high water requirement, so the amount of watering should be appropriately increased, and water should be sprayed at the right times to keep the environment moist. In winter, however, the amount of watering should be controlled, and it is enough as long as the potting soil is not dry; then in early spring, gradually increase the amount of watering again.

Actually, scorched and curled edges on peacock plant leaves are generally caused by temperature and humidity, and the solutions are very simple: just control the amount of fertilizer and water well in normal times and do a good job of drainage. If the plant does not grow tall during the growing process, you can observe it from several aspects such as nutrients, water, and temperature, and then treat it accordingly.
