Understanding Staghorn Ferns
Staghorn ferns (Platycerium species) are epiphytes, which means that they grow on other plants or trees and don’t need soil to survive. They are native to tropical regions and are popular houseplants due to their unique and striking appearance.
Staghorn ferns have two types of leaves: basal and fertile. Basal leaves are flat and shield-shaped, while fertile leaves are antler-shaped and grow upward. The fertile leaves produce spores, which are used for reproduction.
These ferns are relatively low-maintenance and can grow up to several feet wide and tall. They prefer bright, indirect light and high humidity levels, which can be achieved by misting the leaves or placing a humidity tray nearby. Staghorn ferns also require good air circulation to thrive.
One common issue with staghorn ferns is yellowing leaves. This can be caused by a variety of factors, including overwatering, underwatering, pest infestations, or incorrect lighting conditions. It’s important to identify the cause of the yellowing leaves and take appropriate action to remedy the issue.
Staghorn Fern Leaves Turning Yellow – 6 Common Problems
Staghorn ferns are a popular choice for indoor and outdoor gardens, but yellowing leaves can be a common problem. There are several reasons why staghorn fern leaves may turn yellow,.
Here is a detailed explanation of each:
1. Lighting Issues
Lighting issues are a common cause of yellowing leaves in staghorn ferns. These plants require bright, indirect light to thrive. If they are exposed to direct sunlight, their leaves can become scorched and turn yellow. On the other hand, if they do not receive enough light, their leaves may also turn yellow and drop off.
