What to do if the leaves of pennywort turn black

1. What to do if the leaves of the pennywort turn black - light and temperature

Pogostemon cablin is a plant that likes to be cared for. This plant is most suitable for places with sufficient light. When planting Pogostemon cablin at home, if the light is not good, the leaves will wilt and turn black. So if the leaves at home turn black, the first thing you can try is to transplant the Pogostemon cablin outdoors and keep it in sufficient sunlight. The second is temperature. Pogostemon cablin cannot tolerate low temperatures and will no longer survive at around 0 degrees. At the same time, too high a temperature is not suitable for the survival of Pogostemon cablin. The unsuitable temperatures in summer and winter will inevitably cause the leaves of Pogostemon cablin to turn black.

2. What to do if the leaves of catnip turn black - dust and toxins

If the air toxins are too high, the leaves of the plant will turn black. This is because the plant absorbs too many toxins but does not have time to eliminate them, so the leaves will turn black. Or if there is too much dust in the air, the dust covering the surface of the leaves will prevent the leaves from fully absorbing nutrients or incomplete light. If this happens, you can clean the leaves to help the plant detoxify.
