Bergenia: A Tough Perennial for Tricky Spots
Bergenia is a great choice for gardeners who have challenging planting sites. It’s a perennial, meaning it comes back year after year, and it can thrive in a variety of conditions, including shade, full sun, poor soil, and dry areas. Bergenia is also not bothered by deer or rabbits, making it a low-maintenance plant.
Common Bergenia Problems
Even though bergenia is a tough plant, it can still experience some problems. Here are some of the most common issues and how to fix them:
Sunscald
Bergenia can get sunscald if it’s planted in an area with intense afternoon sun. Symptoms of sunscald include yellowing and wilting leaves, brown or crumbly leaves, and stunted growth.
To prevent sunscald, plant bergenia in a location with afternoon shade. If you can’t move the plant, you can try to protect it from the sun by providing shade with a shade cloth or by planting taller plants around it.
Drought
Bergenia can tolerate drought, but it will not do well if it’s not watered regularly. Symptoms of drought stress include wilting leaves, brown leaf tips, and stunted growth.
To prevent drought stress, water bergenia regularly, especially during hot and dry weather.
Waterlogged Soil
Bergenia cannot tolerate waterlogged soil. Symptoms of waterlogged soil include yellowing leaves, wilting, and stunted growth.
To prevent waterlogged soil, plant bergenia in a well-drained location. If you have heavy clay soil, you can improve drainage by adding organic matter, such as compost or peat moss, to the soil.
Fungal Diseases
Bergenia can be susceptible to fungal diseases, especially in damp, humid conditions. Symptoms of fungal diseases include spots on the leaves, wilting, and stunted growth.
To prevent fungal diseases, plant bergenia in a well-drained location and avoid overwatering. You can also improve air circulation around the plants by spacing them properly and pruning away any dead or diseased foliage.
Anthracnose
Anthracnose is a fungal disease that can cause brown or gray sunken lesions on bergenia leaves. The lesions may eventually connect and form larger areas of dead tissue.
To prevent anthracnose, plant bergenia in a well-drained location and avoid overwatering. You can also improve air circulation around the plants by spacing them properly and pruning away any dead or diseased foliage.
Vine Weevil Beetles
Vine weevil beetles are insects that can feed on bergenia leaves. The adults are black and about 1/2 inch long. The larvae are white and C-shaped, and they feed on the roots of bergenia plants.
To prevent vine weevil beetles, keep the area around your bergenia plants clean and free of debris. You can also apply a systemic insecticide to the soil around the plants.
