Ferns are popular plants for outdoor gardens and landscapes due to their lush, green foliage and ability to thrive in shaded areas. However, even with proper care, it’s not uncommon for outdoor ferns to turn brown.
This can be a frustrating and concerning issue for gardeners, as browning foliage is often a sign of distress or disease in plants. So, what causes outdoor ferns to turn brown, and how can you prevent or fix this problem?
There are several reasons why outdoor ferns may turn brown, including:
Overwatering or underwatering
One of the most common causes of browning foliage in outdoor ferns is improper watering. Ferns require consistent moisture to stay healthy, but they can be sensitive to both over- and underwatering. If you’re giving your ferns too much water, the soil may become waterlogged, causing the roots to suffocate and the foliage to turn brown.
On the other hand, if you’re not watering your ferns enough, the soil may become too dry, causing the leaves to wilt and brown. To prevent these issues, it’s important to check the moisture level of the soil regularly and water your ferns as needed.
Poor soil drainage
Another factor that can contribute to browning foliage in outdoor ferns is poor soil drainage. If the soil in your garden doesn’t drain well, excess water may accumulate around the roots of your ferns, causing them to rot and the foliage to turn brown.
To fix this issue, you may need to improve the drainage of your soil by adding organic matter, such as compost, or by creating raised beds for your ferns.
Pest infestations
Pest infestations can also cause outdoor ferns to turn brown. Common pests that may attack ferns include aphids, mealybugs, and mites. These pests can feed on the foliage and stems of ferns, causing the leaves to turn brown and die. To prevent pest infestations, it’s important to regularly inspect your ferns for signs of pests and to use appropriate control methods if necessary.
Disease
Outdoor ferns may also turn brown due to disease. Ferns are susceptible to a variety of diseases, including crown rot, rust, and fern blight. These diseases can cause the foliage of ferns to turn brown and die. To prevent diseases from affecting your ferns, it’s important to follow proper care instructions and to avoid planting ferns in areas with poor air circulation or damp conditions.
Environmental stress
Environmental stress can also cause outdoor ferns to turn brown. For example, ferns may turn brown if they are exposed to prolonged periods of direct sunlight, as they prefer shaded or partially shaded areas.
Similarly, ferns may turn brown if they are exposed to extreme temperatures, such as extreme heat or cold. To prevent environmental stress, it’s important to plant your ferns in an appropriate location that meets their light and temperature requirements.
Preventing and Fixing Browning Foliage in Outdoor Ferns
