Sizing Guide
A simple, flexible guide to choosing the right plant support size.
Start here (30-second answer)
Choose a support that reaches your plant’s current height.
From there, you can size up as much as you like based on how you want it to look and grow.
- Stabilizing: reach the section that needs support
- Encouraging growth: match the plant’s height (or taller, if you prefer)
- Shaping: choose the size that fits the form you want now
The one rule that matters
Support height should meet your plant where it is today.
Anything taller than that is optional and comes down to aesthetics, space, and how far ahead you want to plan.
Step 1: What is your plant doing right now?
Pick the option that best matches what you see.
It wants to climb upward
What to look for:
- Vining or aerial-rooted growth
- Stems reaching upward or attaching to nearby surfaces
- New growth searching for something higher
Best supports:
It’s spreading outward
What to look for:
- Trailing or bushy growth
- Stems pushing out to the sides
- Needs shaping more than vertical height
Best supports:
It’s wobbling or leaning
What to look for:
- Thin stems that bend or flop
- Top-heavy growth
- Needs subtle stabilization
Best supports:
Step 2: Choose a height for the next 8–12 weeks
These guidelines describe the minimum height needed to support your plant right now.
You can always choose a taller support if you prefer the look or want more room to grow.
-
If you’re just stabilizing:
Choose a support that reaches the section of the plant that needs support. Taller is fine if you don’t mind the extra height. -
If you’re encouraging vertical growth:
Choose a pole that reaches your plant’s current height. You may size up to give the plant room to climb into over time. -
If you’re shaping growth:
Choose a hoop or flexible pole that matches the shape you want now, or size up if you prefer a more open structure.
If your plant is between sizes, any option that reaches its current height will work.
Choosing a taller size is an aesthetic and planning choice, not a requirement.
Step 3: Choose by product type
Stackable coir poles and fillable support poles
- Start with a pole that reaches your plant’s current height.
- Extend or stack when growth reaches past the top.
- Use plant tape to secure the stems and guide new growth gently.
Flexible plant support poles
- Choose based on the shape you want to guide.
- Reposition as growth changes.
- Well suited for training vines and redirecting growth over time.
- Use plant tape to secure the stems and guide new growth gently.
Glassvine supports
- Match the height of the section that needs stabilization.
- Designed for subtle support with minimal visual presence.
- Use multiple supports for heavier or multi-stem plants.
- Use trellis clips to guide new growth gently.
Glassvine hoops
- Choose based on the spread you want to control.
- Ideal for shaping and gently gathering outward growth.
- Use multiple hoops for wider or fuller plants.
- Use trellis clips to guide new growth gently.
When to size up or stack
It’s time to add height or support when:
- Growth reaches the top of the support
- Stems begin leaning outward again
- New growth is searching for something higher
- Aerial roots are reaching beyond the support
Stacking is normal. Supports, plants, and pots often grow together over time.
Frequently asked questions
Does pot size matter?
Yes. Pot size affects both plant health and stability.
Match support height to the plant, but make sure the pot is deep and heavy enough to anchor it safely. Taller supports require more stable pots to prevent tipping.
- A taller support needs a deeper, heavier pot.
- Roots need enough space to support healthy growth above the soil.
- An undersized pot can limit growth and increase instability.
As plants grow taller, it’s often helpful to increase pot size along with support height.
What if my plant is between sizes?
This is mostly an aesthetic choice.
As long as the support reaches your plant’s current height, it can be taller without harming the plant. Some people prefer a taller pole from the start so the plant can grow into it.
- Choose a shorter size for a more minimal look.
- Choose a taller size if you don’t mind the visual height or want fewer upgrades later.
Both options work — the right choice depends on your space and preferences.
When should I stack a support?
When growth reaches the top and begins leaning or searching for more support. Add height gradually as the plant grows.
