Beautyberry (Callicarpa americana) is a deciduous shrub found naturally in the southeastern United States. It grows between 3 and 6 feet tall and wide on average, though its been known to reach 9 feet tall. It has a moderate growth rate, gaining around 1 to 2 feet per year until it is mature, and it can be planted in the fall or spring.
Beautyberry plants tolerate full sun to partial shade, and while they like moist soil, they can tolerate somewhat dry conditions. Enjoyed mainly by wildlife, humans can also consume beautyberries, best served as a jelly.
If you’ve noticed brown spots on the leaves or berries of your American beautyberry shrub, it can be worrying. But don’t fret! Brown spots are common in these shrubs, and with the right care you can get your plant thriving again.
In this article we’ll walk through the top causes of brown spots in American beautyberry and how to fix them. We’ll also share tips to keep your shrub healthy and prevent problems in the future. Let’s dig in!
Common Causes of Brown Spots
Here are the usual suspects when it comes to brown spots on American beautyberry:
Fungal Diseases
Fungal diseases like anthracnose are a prime cause of brown spots. These fungi cause dark, sunken lesions on leaves and berries that can expand, killing off areas of the plant Pruning for air circulation, avoiding overhead watering, and using fungicides if needed can help.
Sunburn
Too much harsh sunlight can actually burn American beautyberry leaves and berries, leaving brown sunburn spots on exposed areas. Relocating to partial shade or providing shade covers during intense sunlight prevents this.
Pests
Spider mites, aphids, caterpillars and other critters feed on beautyberry, causing brown damage. Regular inspections, insecticidal soap or neem oil treatment, and pruning of heavily infested parts helps get rid of them.
Nutrient Deficiency
Lack of nitrogen, potassium, magnesium and other nutrients shows first as yellowing or browning on leaf edges and tips. Address with balanced fertilizer in early spring and late fall to nourish beautyberry.
Environmental Stress
Heat, drought, temperature shifts and poor drainage stress the plant, eventually causing brown spots on leaves and berries. Adequate water, mulching for moisture retention and soil amendments prevent this.
Caring for Your American Beautyberry
While brown spots are common on American beautyberry, a little TLC goes a long way in preventing and treating issues. Here are our top care tips:
-
Water carefully – Too much or too little water causes problems. Check soil moisture before watering and aim for consistently moist but not soaked soil.
-
Fertilize occasionally – Use a balanced shrub fertilizer in early spring and late fall to provide nutrients. Avoid over-fertilizing.
-
Give it partial shade – Dappled sunlight, like that under a tree canopy, is ideal for American beautyberry. Move potted plants or use shade covers as needed.
-
Watch for pests – At the first sign of mites, aphids, caterpillars or other bugs, take action with insecticidal soap, neem oil or targeted pruning.
-
Prune for airflow – Remove overlapped inward facing branches to open up air circulation and prevent fungal disease.
-
Check soil drainage – Beautyberry thrives in moist but well-draining soil. Amend dense or compacted areas as needed.
-
Add mulch – A 2-3 inch layer of mulch helps regulate soil temperature and moisture to prevent stress. Replenish annually.
When to Worry About Brown Spots
In most cases, a few brown spots here and there are purely cosmetic and your American beautyberry will continue thriving with good care. But if you notice:
- Expanding brown lesions that are killing large areas of leaves or berries
- Excessive leaf loss
- Lack of new growth
- Wilting, dying branches or other signs of major stress
It’s time to take action. Rule out and address pest, disease and care issues right away before they worsen. You may need to consult a local expert for diagnosis and treatment if problems persist.

Types of Beautyberry
American beautyberry plants (Callicarpa americana) grow natively in the U.S.; therefore, they are not invasive but can have weedlike properties. Non-native varieties like Callicarpa dichotoma, native to Asia, are considered invasive in Alabama.
There are several types of American beautyberry (Callicarpa americana), including:
- Alba: This beautyberry shrub is known for its white berries.
- Lactea: This beautyberry also features white fruits.
- Welchs Pink: This shrub is known for its pink berries.
Propagating Beautyberry
The beautyberry shrub will reseed itself, and you can propagate it by digging out volunteer seedlings that pop up around the plant and replanting them in a new location. You can also propagate the shrub from cuttings in late spring or early summer. This is an inexpensive and easy way to make more of a shrub variety that you particularly like. Heres how:
- Cut a section of healthy stem thats around 6 inches long. Avoid old woody stems.
- Remove any leaves on the lower half of the cutting.
- Dip the cut end in rooting hormone and plant it in a small container filled with moist, soilless potting mix.
- Put a clear plastic bag over the container to help retain moisture, and place the container in bright, indirect light.
- Keep the soil evenly moist but never soggy. Once you see notable foliage growth, youll know roots have formed. It can take about two to three months for substantial root growth. Then, the new shrub is ready for transplanting.
