Reasons and treatments for yellow leaves of moonflower

1. Temperature discomfort

Reason: The temperature suitable for its growth is generally between 15-28 degrees. Temperatures that are too high or too low will affect its normal growth, and the plant will show signs of yellow leaves due to frostbite from low temperature or lack of water from high temperature.

Solution: When the temperature is too low, the plant needs to be placed in a warm place indoors for maintenance, and wait for the plant's stem to recover slightly before starting normal maintenance. When the temperature is too high, place it in a cool place with good ventilation. Spray some water on the surface of the leaves to achieve a cooling effect.

2. Overwatering

Reason: It likes to grow in a relatively humid environment and has a higher demand for water. In this way, it is easy to overwater, causing water accumulation in the pot, leading to root rot and yellowing of leaves.

Solution: You need to immediately control watering and stop fertilizing. Then loosen the soil frequently to ensure good soil ventilation. Then move the plant to a ventilated and well-lit place so that excess water in the soil can evaporate as quickly as possible.

3. Too much light

Reason: Its normal growth requires sufficient warm sunlight, and enough light can make it bloom normally. However, if exposed to strong sunlight in summer, the leaves will turn yellow.

Treatment: First place it in a cool place with only diffuse light, then spray some water on the leaves, water it in small amounts, and wait for it to recover. After the leaves of the plant have slightly returned to normal, place it in a semi-sunny place for maintenance, or block out strong light. In addition, make sure you get at least 4 hours of sunlight every day.

4. Pests

Reason: Aphids are a very harmful insect pest. It is a serious threat to more than 250 species of plants, and moonflower is one of them. This pest mainly sucks the sap from the plants, causing a large loss of nutrients, gradually turning yellow and eventually withering.

Treatment: Medication should be used immediately. You can directly use 1500-2000 times diluted 40% imidacloprid water solvent or 3000 times diluted 50% cypermethrin wettable powder to spray it directly. Then place the plant in a ventilated and well-lit place to allow it to recover.
