Solutions for heartleaf philodendron dropping leaves

This situation is thought to have two causes. More than half of the time it is due to overwatering. Do not water frequently. Generally, heartleaf philodendron should be watered once every 5-6 days. Second, insufficient scattered light is also one of the main causes of leaf yellowing and leaf drop. Although it likes shade, make sure it gets plenty of scattered light.

At this time, it should be placed in a ventilated environment with plenty of scattered light. Do not water when the white area on the surface of the potting soil is no more than 50%. If you take careful care of it in daily life, you can use a spray bottle to mist the leaf surface to increase relative humidity (you can also add 0.01% urea dissolved in water for spraying).

How to grow heartleaf philodendron

1. Light requirements

Heartleaf philodendron does not have high light requirements, but it still needs a little light. Keep 4-6 hours of light every day. It can be placed outside for a long time to get more sunlight, but in winter the weather is relatively cold and at night the plant may be frostbitten.

Therefore, pay more attention and provide some cold protection when necessary. In summer, the sunlight is too strong, so shade measures are needed, otherwise the leaves will be damaged.

2. Humidity requirements

The humidity condition needs to change according to the season. Humidity is different in different seasons. In summer, water a little more to prevent water from evaporating too quickly and causing water shortage. In winter, water less. You can water appropriately, and it is best not to water at noon.

Because the temperature is highest and hottest at noon, and the plant's stomata are fully open. Watering at this time will damage the plant's stomata and restrict its growth.

3. Temperature requirements

The best temperature most suitable for the growth environment of heartleaf philodendron is between 5-15 degrees, so we should learn to control the temperature. In summer, we can take shading measures to prevent strong ultraviolet rays from damaging heartleaf philodendron. In winter, pay attention to heat preservation to avoid freezing to death in low-temperature weather.
