How to Choose Glass Jars for Pothos
Pothos (Epipremnum aureum) is one of the most popular indoor plants, loved for its trailing vines, heart-shaped leaves, and easy-going nature. While pothos grows well in soil, many plant lovers prefer growing it in water using glass jars. Glass jars not only highlight the beauty of pothos roots but also add a modern, decorative touch to homes and offices.
However, not all glass jars are suitable for growing pothos. Choosing the right jar plays a major role in plant health, root development, and overall aesthetics.
In this blog, we’ll explore how to choose the perfect glass jars for pothos, covering size, shape, color, drainage considerations, and maintenance tips.

Why Grow Pothos in Glass Jars?
Growing pothos in glass jars has several advantages:
- Allows you to monitor root health easily
- Looks elegant and modern in indoor spaces
- Ideal for water propagation and hydroponic growth
- Requires less mess compared to soil
Glass jars are especially popular for tabletops, shelves, work desks, and hanging displays.
1. Choose the Right Size of Glass Jar
Size is the first and most important factor when selecting a glass jar for pothos.
Small Jars
Small jars are suitable for:
- Single pothos cuttings
- Newly propagated plants
- Desk or window-sill displays
However, small jars dry out faster and may restrict root growth over time.
Medium to Large Jars
Medium or large jars are ideal for:
- Mature pothos plants
- Multiple cuttings growing together
- Long-term water growth
Ensure the jar provides enough space for roots to spread freely without crowding.
Tip: The jar should be tall enough so roots remain submerged while leaves stay above water.

2. Select the Correct Shape
The shape of the glass jar directly affects plant stability and root health.
Narrow Neck Jars
- Hold cuttings upright
- Prevent stems from falling into water
- Best for single or few cuttings
Wide-Mouth Jars
- Easier to clean
- Allow better air circulation
- Ideal for bushier pothos plants
Avoid jars with extremely narrow bases, as they can tip over easily once the plant grows.

3. Transparent vs Colored Glass Jars
Transparent Glass Jars
Pros:
- Easy to monitor root growth
- Identify algae, rot, or water issues quickly
- Visually appealing root display
Cons:
- Encourages algae growth if exposed to direct sunlight
Colored or Frosted Glass Jars
Pros:
- Reduces algae formation
- Adds decorative value
- Protects roots from excessive light
Cons:
- Harder to inspect root condition
Best option: Use clear glass jars and place them in bright indirect light rather than direct sunlight.
4. Thickness and Quality of Glass
Always choose jars made of thick, sturdy glass. Thin glass may crack due to:
- Temperature changes
- Frequent water changes
- Accidental knocks
High-quality glass ensures durability and safety, especially if you’re placing jars near windows or high-traffic areas.
5. Consider Drainage (or Lack of It)
Glass jars usually do not have drainage holes, which is fine for water-grown pothos.
For soil-grown pothos in glass jars:
- Add a layer of pebbles or gravel at the bottom
- Use activated charcoal to prevent odor and fungal growth
- Water sparingly to avoid root rot
Water-grown pothos is generally easier to maintain in glass containers.
6. Stability and Placement
A good glass jar should be stable and well-balanced. Consider:
- Flat, wide base for stability
- Weight of water and plant
- Placement on sturdy surfaces
For hanging pothos, use thick glass jars with strong rope or metal holders designed for plant displays.
7. Easy Cleaning and Maintenance
Glass jars should be easy to clean to prevent:
- Algae buildup
- Mineral deposits
- Bad odors
Wide-mouth jars make cleaning easier. Wash jars every 2–3 weeks and change water regularly to keep roots healthy.
8. Aesthetic and Interior Décor
Glass jars are as much about style as they are about function. Choose jars that:
- Match your interior theme
- Complement furniture and wall colors
- Enhance the natural beauty of pothos vines
Minimalist, cylindrical jars work well in modern homes, while vintage glass jars suit rustic or bohemian décor.
Conclusion
Choosing the right glass jar for pothos is essential for healthy growth and visual appeal. Focus on the right size, shape, transparency, and stability to create the perfect environment for your plant.
With proper care and the right jar, pothos can thrive beautifully in water, adding greenery and elegance to any space.
