Quick comparison at a glance

Coir poles

• Great for steady, vertical training

Fillable poles

• Customizable substrate for moisture and texture control
• More hands-on setup
• Easy to adjust as your plant matures

Which is better for climbing plants?

Coir poles are a simple, reliable choice for most climbing plants. The natural texture encourages aerial roots to attach and climb. If you want a classic support you can install quickly, a coir pole is usually the best fit. Start with the coir poles collection or the Stackable Coir Pole.

Fillable poles are best when you want control over the substrate. If your plant prefers a specific moisture level or you want to experiment with a custom mix, fillable poles make that easy. See fillable poles or the Stackable Support Pole.

Practical advice from growers

• If you are new to climbing supports, start with coir.
• If you already know what substrate your plant prefers, fillable poles give you more control.
• Both options work well for long-term growth when sized correctly.

Common mistakes to avoid

Choosing a pole that is too tall from the start

Pick a height close to your plant's current size and stack later.

Overpacking a fillable pole

Fill gradually and keep the substrate breathable so roots can attach.

Letting a climber sprawl too long

Supports work best when introduced early.

FAQ

Yes. As long as you keep the height appropriate and guide the stems gently, most climbers adapt well.

Which one holds moisture better?

Fillable poles can hold more moisture depending on what you add. Coir poles are more consistent and lower maintenance.

Do both options stack?

Yes. Both are designed to grow with your plant over time.
