Tropical herbs that prefer full shade can be extremely sensitive to direct sunlight. If your plant is exposed to too much light, the leaves may start to turn yellow or brown and may eventually drop off. Additionally, the plant may become stunted and stop growing. If you notice any signs of sunburn or overexposure to light, move your plant to a shadier location or provide it with additional shade. In conclusion, understanding the sunlight requirements of your tropical herbs is crucial to keeping them healthy and happy. Full shade tropical herbs require only a few hours of indirect light each day to thrive, and ensure that the plant is never exposed to too much sunlight. By providing your plant with the right amount of light and shade, you can help ensure that it grows strong and healthy.
