Cebu Blue Pothos Climbing: How to Encourage Vertical Growth
The Cebu Blue Pothos (Epipremnum pinnatum ‘Cebu Blue’) is a popular tropical plant known for its stunning silvery-blue foliage and unique climbing ability. This plant can either trail from a hanging basket or climb up a support structure, and encouraging it to climb can lead to larger, more mature leaves with the potential to develop fenestrations (leaf splits).
If you want to help your Cebu Blue Pothos reach its full climbing potential, this guide will walk you through everything you need to know.

1. Why Encourage Climbing in Cebu Blue Pothos?
In its natural habitat, the Cebu Blue Pothos climbs trees and other vertical surfaces in the tropical forests of the Philippines. When it climbs, the plant mimics its natural growth pattern, producing larger leaves with more vibrant coloration. As the plant matures, it may also develop the highly sought-after fenestrations (splits or holes in the leaves), which are rarely seen in trailing plants.
Key Benefits of Climbing:
- Larger Leaves: Climbing encourages bigger, more mature foliage.
- Fenestrations: Leaf splits are more likely to appear as the plant matures while climbing.
- Better Light Exposure: A climbing plant gets better access to light, which promotes healthier growth.
2. Providing Support for Cebu Blue Pothos
To encourage your Cebu Blue Pothos to climb, the first step is to provide it with a vertical support structure. In its natural environment, the plant climbs trees using its aerial roots. You can replicate this by giving your plant something to cling to.
Types of Support Structures:
- Moss Pole: One of the most popular options for pothos plants. Moss poles mimic the texture of tree bark and provide a moist surface that encourages aerial roots to attach.
- Trellis: A trellis works well for those who want a more decorative support structure. It allows the plant to climb in multiple directions.
- Coir Pole: Similar to a moss pole but made of coconut coir, which also helps retain moisture and offers a rough texture for aerial roots to grip.
- Wall or Shelf: If you don’t want to use a traditional pole or trellis, you can train the plant to climb a wall or along a shelf using small plant clips.
How to Train Cebu Blue to Climb:
- Position the Plant Close to the Support: Place your Cebu Blue Pothos near its support structure. As it grows, guide the vines onto the structure by loosely tying them using plant ties or clips.
- Encourage Aerial Roots: Keep the moss or coir pole moist. Cebu Blue develops aerial roots that latch onto surfaces when there is enough humidity. Regular misting of the support structure will help the roots grip.
- Patience is Key: It may take time for the plant to adjust to climbing, but once the aerial roots start anchoring, the plant will climb steadily.
3. Optimal Growing Conditions for Climbing
Creating the right environment is essential for your Cebu Blue Pothos to grow vertically and thrive. Proper light, water, humidity, and nutrients are key factors that contribute to healthy growth and climbing.
Light Requirements
To encourage your Cebu Blue Pothos to climb and develop larger leaves, ensure it receives bright, indirect light. Inadequate light can lead to leggy growth and smaller, less mature leaves.
- Ideal Location: Place the plant near an east or north-facing window for bright, filtered light.
- Artificial Lighting: If natural light is insufficient, you can supplement with grow lights to ensure your plant gets at least 6-8 hours of light per day.
Watering
Cebu Blue prefers a balance between moist and dry soil. Overwatering can lead to root rot, while underwatering can stunt its growth.
- Watering Schedule: Water the plant when the top 2 inches of soil are dry. Make sure the pot has proper drainage to prevent waterlogging.
- Watering Technique: Water thoroughly, allowing the excess to drain out of the pot, and avoid letting the plant sit in standing water.
Humidity and Temperature
Since Cebu Blue Pothos is native to tropical environments, it prefers high humidity levels and warm temperatures.
- Humidity Levels: Keep the humidity around 50-70%. You can boost humidity by misting the plant, using a humidity tray, or placing a humidifier nearby.
- Temperature: Cebu Blue Pothos thrives in temperatures between 65-85°F (18-29°C). Avoid placing the plant near drafts, heaters, or air conditioners, which can cause temperature fluctuations.
Fertilizing
To support the plant’s vertical growth and promote larger leaves, regular feeding is necessary during the growing season.
- Fertilizer Type: Use a balanced, water-soluble fertilizer (such as 20-20-20) once a month during the spring and summer.
- Avoid Over-fertilizing: Excess fertilizer can lead to salt buildup in the soil, which can harm the roots. Always follow the recommended dosage on the fertilizer label.
4. How Climbing Affects Leaf Development
One of the most exciting aspects of training your Cebu Blue Pothos to climb is seeing how the leaves transform as the plant grows vertically. In its juvenile stage, the leaves are typically small and narrow, with a smooth texture. However, as the plant climbs and matures, the leaves become larger, and in some cases, develop fenestrations.
Fenestrations in Mature Leaves
Fenestrations, or natural splits in the leaves, are one of the most desirable features of a mature Cebu Blue Pothos. While not all plants will develop fenestrations, encouraging vertical growth increases the chances of seeing these splits.
- Triggering Fenestrations: Providing the plant with ample light, humidity, and vertical support can encourage the development of fenestrations.
- Time and Patience: Fenestrations often appear in older plants after they’ve had time to climb and grow. It may take months or even years for your plant to reach this stage.
5. Common Issues When Training Cebu Blue Pothos to Climb
While Cebu Blue Pothos is generally easy to care for, there are a few common issues that may arise when training the plant to climb.
1. Leggy Growth
Leggy growth occurs when the plant is stretching towards light, producing long stems with few leaves. This is a sign that the plant is not receiving enough light.
- Solution: Move the plant to a brighter location with more indirect light or supplement with grow lights to ensure it gets enough energy for healthy growth.
2. Slow Climbing Progress
If your Cebu Blue Pothos is slow to climb, it may be due to a lack of humidity or inadequate support.
- Solution: Mist the moss pole or support regularly to encourage aerial roots to attach. Ensure that the plant is close enough to the support structure so it can start climbing.
3. Browning Leaves
Browning tips or edges can be caused by overwatering, underwatering, or low humidity.
- Solution: Adjust your watering routine and consider increasing humidity by misting the plant or using a humidifier.
6. Final Thoughts on Cebu Blue Pothos Climbing
Training your Cebu Blue Pothos to climb can result in a stunning display of large, mature leaves that add a vertical element to your indoor garden. By providing the right support, light, and care, you can encourage your plant to reach new heights—literally—and possibly reward you with the beautiful fenestrations that make this plant so unique.
Encouraging climbing in your Cebu Blue is not only beneficial for the plant’s growth but also enhances its beauty, making it a showstopper in any plant collection.
