Sky Pencil Holly Turning Brown: Causes and Solutions

Sky Pencil Holly is a popular ornamental plant known for its unique vertical growth and evergreen foliage. However, witnessing your Sky Pencil Holly turning brown can be disheartening.

In this article, we will explore the various causes of browning leaves in Sky Pencil Holly and provide practical solutions to help you save and care for your plant.

Causes of Sky Pencil Holly Turning Brown  with Solutions

1. Overwatering

Overwatering is a common cause of browning leaves in Sky Pencil Holly. When the roots are constantly saturated, they can’t absorb oxygen properly, leading to root rot.

Signs of overwatering include wilting, yellowing leaves, and soggy soil. To determine if overwatering is the cause, check the moisture level of the soil and examine the roots for any signs of decay.


Allow the soil to dry out between watering. Water the plant when the top 2 inches of soil are dry. Ensure proper drainage by using well-draining soil and pots with drainage holes. Avoid overwatering and do not let the plant sit in standing water.

2. High Temperature

Sky Pencil Holly prefers moderate temperatures between 55°F and 85°F. Excessive heat can stress the plant and cause the leaves to turn brown. In hot climates, the plant may benefit from some shade or protection during the hottest part of the day.


Place the plant in a cool location or provide shade during the peak hours of intense sunlight. Mulching around the base of the plant can help maintain soil moisture and regulate temperature.

3. Dry Wind

Dry wind can dehydrate the plant, increasing transpiration and causing the leaves to dry out and turn brown. This is especially common in windy environments or during drought conditions.


Water your plant regularly during hot and windy weather to maintain adequate moisture. Consider creating a windbreak using hedges, fences, or other plants to protect the Sky Pencil Holly from strong winds.

Additionally, misting the leaves or using a humidifier indoors can help increase humidity levels and reduce the drying effect of the wind.

4. High Humidity

While Sky Pencil Holly doesn’t thrive in high humidity, extremely low humidity can cause leaf discoloration. Excessively humid environments can promote fungal diseases and result in browning leaves.


Avoid placing the plant in excessively humid environments. Maintain humidity around 50% by placing it in well-ventilated areas or using a dehumidifier. Ensure proper air circulation around the plant to prevent the development of fungal diseases.

5. Over-fertilization

Over-fertilization or using improper fertilizing methods can lead to nutrient imbalances and burn the leaves of Sky Pencil Holly, resulting in browning.


Fertilize your plant once a year in spring using a slow-releasing, balanced liquid fertilizer. Dilute the fertilizer in water and apply it during watering.

Avoid over-fertilization and follow the recommended dosage. If over-fertilization has occurred, flush the soil with water to remove excess salts and nutrients.

6. Pest Infestation

Pests like aphids, scales, and spider mites can damage the leaves of Sky Pencil Holly, causing them to turn brown and wither.


Handpick small numbers of insects from the leaves or use a strong jet of water to dislodge them. For larger infestations, use insecticidal soaps or horticultural oils as per the manufacturer’s instructions.

Regularly inspect your plant for signs of pests and take prompt action.

   – Planting depth: Place the Sky Pencil Holly in the hole, ensuring that the top of the root ball is level with or slightly above the ground.

   – Backfill and water: Fill the hole with soil, gently firming it around the roots. Water thoroughly after planting to settle the soil.


   – Initial watering: After planting, water the Sky Pencil Holly deeply to promote root establishment.

   – Regular watering: Once established, water the plant regularly, providing approximately 1 inch of water per week. Adjust the frequency based on weather conditions, ensuring the soil remains moist but not waterlogged.

   – Mulching: Apply a layer of organic mulch around the base of the plant to help retain moisture and suppress weed growth.


   – Shaping and maintenance: Sky Pencil Holly has a naturally columnar growth habit, but occasional pruning can help maintain its desired shape. Prune in early spring before new growth emerges.

   – Removing dead or diseased branches: Regularly inspect the plant and remove any dead, damaged, or diseased branches to promote overall health and appearance.


   – Timing: Apply a balanced, slow-release fertilizer in early spring before new growth starts.

   – Application: Follow the manufacturer’s instructions and apply the fertilizer evenly around the base of the plant.

   – Avoid over-fertilizing: Excessive fertilizer can lead to nutrient imbalances and leaf burn. Use fertilizers sparingly and avoid contact with the foliage.

Protection from Extreme Conditions

   – Temperature: Sky Pencil Holly is hardy in USDA zones 5-9. Protect the plant from extreme cold or heat by providing adequate insulation or shade during harsh weather conditions.

   – Wind protection: Strong winds can damage the foliage. Consider planting the Sky Pencil Holly near a windbreak or using a temporary windscreen during windy periods.

Pest and Disease Management

   – Regular inspection: Monitor the plant for signs of pests such as aphids, scales, or spider mites. Look for symptoms of diseases such as leaf spots or powdery mildew.

   – Prompt action: If pests or diseases are detected, take appropriate measures such as using insecticidal soaps, horticultural oils, or fungicides as recommended.


   – Division: Sky Pencil Holly can be propagated through division. Divide the plant during its dormant period, ensuring each division has roots attached.

   – Stem cuttings: You can also propagate Sky Pencil Holly from stem cuttings taken during the spring or summer. Dip the cuttings in rooting hormone and plant them in a well-draining medium.

By following these care guidelines, you can help your Sky Pencil Holly thrive and maintain its attractive appearance throughout the seasons.

Regular watering, proper pruning, appropriate fertilization, and vigilant pest and disease management will contribute to the long-term health and beauty of your plant.
