Solution Increase humidity by misting leaves or placing a tray of water nearby.

The reason why houseplant leaves turn brown is due to excessive exposure to direct sunlight. When houseplants receive too much direct sunlight, it can cause the leaves to become scorched, resulting in browning or yellowing. This occurs because the intense sunlight damages the plant cells, leading to discoloration.

To address this issue, it is essential to provide shade or move the houseplant to a location with less direct sunlight. Placing the plant near a window with sheer curtains or blinds can help filter the intense light. Additionally, rotating the plant regularly can ensure that all sides receive an equal amount of light, preventing uneven browning.

In cases where it is not possible to relocate the plant, using a UV-filtering film on the windows or applying a sheer cloth over the plant during peak sunlight hours can help reduce the intensity of direct sunlight. Furthermore, providing adequate watering and ensuring proper humidity levels can also contribute to maintaining healthy foliage and preventing leaf browning.

By addressing the issue of too much direct sunlight, implementing shading techniques, and maintaining appropriate plant care practices, the browning of houseplant leaves can be mitigated, allowing them to thrive and maintain their vibrant green color.
