Pachysandra is an evergreen groundcover plant that is commonly used to cover large areas of ground. Its scientific name is Pachysandra terminalis. It is a low-maintenance plant that is ideal for shady areas and can grow up to 10 inches in height.

It is known for its glossy, dark green leaves that form a dense mat, making it an excellent choice for erosion control.

One of the most common issues with Pachysandra is the yellowing of its leaves. This can be caused by a variety of factors, including excessive sunlight, waterlogging, pest infestation, chlorosis, and soil with insufficient nutrients.

Yellowing leaves can be a sign that your Pachysandra is not receiving the proper care and attention it needs to thrive.

To prevent your Pachysandra from turning yellow, it is important to ensure that it is planted in the right location. Pachysandra thrives in partial to full shade, making it an ideal choice for planting under trees or in areas with limited sunlight.

It is also important to ensure that the soil is well-draining and not waterlogged, as this can lead to root rot and yellowing leaves.

Regular fertilization is also essential to keep your Pachysandra healthy. A balanced fertilizer with equal amounts of nitrogen, phosphorus, and potassium can help to provide the plant with the nutrients it needs to thrive. Additionally, regular pruning can help to promote healthy growth and prevent the plant from becoming too dense.

Pachysandra Turning Yellow – 4 Common Problems

Pachysandra is a popular ground cover plant that adds an attractive touch of greenery to any garden. However, yellowing of leaves is a common problem that gardeners face while growing pachysandra. In this section, we will discuss the most common causes of yellowing in pachysandra.

1. Sunlight Exposure

Excessive sunlight exposure is one of the primary reasons for pachysandra leaves turning yellow. When pachysandra is exposed to too much direct sunlight, the leaves can become bleached out, resulting in light green to yellow foliage.

To fix this issue, the pachysandra plant should be moved to a partially shaded area. Alternatively, a good ground cover plant that thrives in full sunlight conditions is Cotoneaster.

2. Watering Issues

Both overwatering and underwatering can cause yellowing of leaves in pachysandra. Overwatering can lead to root rot and other fungal diseases, while underwatering can cause drought stress.

To ensure that the pachysandra plant is getting the right amount of water, gardeners should water it deeply once a week during the growing season. During the winter months, watering should be reduced to once every two weeks.

3. Nutrient Deficiency


Pachysandra requires a balanced supply of nutrients to grow and thrive. A nutrient-deficient soil can cause yellowing of leaves in pachysandra. Nitrogen is one of the essential nutrients required by pachysandra.

A nitrogen-deficient soil can lead to yellowing of leaves and stunted growth. Gardeners can add a nitrogen-rich fertilizer to the soil to correct this deficiency.

4. Disease and Pest Infestation

Pachysandra is susceptible to various diseases and pests, which can cause yellowing of leaves. Chlorosis is a common disease that affects pachysandra, causing yellowing of leaves due to a lack of chlorophyll.

Pests such as spider mites, scale insects, and mealybugs can also cause yellowing of leaves in pachysandra. Gardeners should monitor their plants for signs of disease and pests and take appropriate action to prevent or treat infestations.

Diagnosing Pachysandra Problems

Pachysandra is a popular ground cover plant that is known for its lush green foliage and ability to grow in shady areas. However, sometimes pachysandra can turn yellow, which is a sign that something is wrong. In this section, we will discuss how to diagnose pachysandra problems and identify the possible causes.

Visual Inspection

One of the first things to do when diagnosing pachysandra problems is to perform a visual inspection of the plant. Look for signs of damage, blight, fungal disease, root rot, volutella blight, or any other visible symptoms.

Check the leaves for brown spots, yellowing, or any other discoloration. Look for webbing or spider mites, which can be a sign of insect infestation. Also, check for euonymus scale, a common pest that can cause yellowing and leaf drop.

Soil Testing

Another important step in diagnosing pachysandra problems is to test the soil. Soil testing can help identify any nutrient deficiencies or soil pH imbalances that may be causing the yellowing.

Pachysandra prefers a slightly acidic soil with a pH between 5.0 and 6.5, so if the soil is too alkaline, it can cause yellowing. Additionally, soil testing can help identify any fungal diseases or root rot that may be present.

To perform a soil test, collect a soil sample from around the pachysandra roots and send it to a soil testing laboratory. The laboratory will analyze the soil and provide recommendations for any necessary amendments.

Treatment and Prevention Strategies

1. Proper Watering and Drainage

Proper watering and drainage are essential for the health of pachysandra plants. Overwatering can lead to root rot, which can cause the plant to turn yellow and die. To prevent this, make sure the soil is well-draining and does not become waterlogged. A good way to ensure proper drainage is to provide a ditch to drain excess water away.

During the growing season, pachysandra plants should be watered regularly, but not excessively. Watering should be done in the early morning or late evening to prevent the water from evaporating too quickly and to allow the plant to absorb the water properly.

2. Nutrition and Fertilization

Pachysandra plants require essential nutrients for healthy growth. If the soil is poor in nutrients, the plant may turn yellow. To prevent this, fertilizers can be applied to the soil in early spring or fall. Slow-release fertilizers, such as Miracle-Gro, can be used to provide essential nutrients over a longer period of time.

Organic matter, such as compost or well-rotted manure, can also be added to the soil to improve its quality and provide essential nutrients. Mulch can be used to help retain moisture and prevent weeds.

3. Disease and Pest Management

Pachysandra plants can be susceptible to diseases and pests, which can cause the plant to turn yellow and die. Common diseases that affect pachysandra include Volutella blight and Phytophthora root rot. These diseases can be managed by pruning affected areas and replanting in a different area.

Insecticidal soap can be used to control pests such as spider mites and mealybugs. Chemicals should be used as a last resort and only if necessary. It is important to follow the instructions carefully and use them in the recommended amounts.

Maintaining proper soil pH is also important for the health of pachysandra plants. The ideal pH range for pachysandra is between 5.5 and 6.5. Too much acidic or alkaline soil can lead to poor growth and yellowing of the leaves. Testing the soil pH and adding lime or sulfur as necessary can help maintain the proper pH level..

Replanting and Care for Pachysandra

Best Time to Replant

The best time to replant pachysandra is in early spring when the soil is moist and the temperatures are cool. This allows the plant to establish its roots before the hot summer months. If replanting is necessary during the summer, it is important to keep the plant well-watered to prevent it from drying out.

Preparing the Planting Bed

Before replanting, it is important to prepare the planting bed properly. Remove any weeds, rocks, or debris from the area and loosen the soil to a depth of at least 6 inches.

Pachysandra prefers slightly acidic soil with a pH between 5.0 and 6.0. If the soil is too alkaline, add sulfur to lower the pH. If the soil is too acidic, add lime to raise the pH.

Long-Term Care

After replanting, it is important to provide proper care to ensure healthy growth. Pachysandra prefers shade or partial shade and moist, well-drained soil. Water the plant regularly, especially during dry periods, but avoid overwatering as this can lead to root rot.

Apply a layer of mulch around the plant to help retain moisture and suppress weeds.

Fertilize the plant in early spring with a balanced fertilizer to promote healthy growth. Avoid fertilizing in late summer or fall, as this can stimulate new growth that may not have time to harden off before winter.

If pachysandra is turning yellow and dying, it may be a sign of a larger issue. Check for pests or diseases and take appropriate action. Renovate the planting bed periodically to prevent the buildup of diseases and pests. If the problem is severe, consider replanting the plant in soil with better drainage.
