190mm – 2.5L Anti Spiral Pot (Air Pruning Pot)

The 190mm 2.5L Anti Spiral Pot is a professional-grade aerial root pruning container designed to optimize plant health and root structure. Engineered to eliminate root circling, this pot utilizes specialized internal geometry to guide roots toward air-ventilated openings, triggering natural pruning and the development of a vigorous, fibrous root system.

Manufactured in Australia to commercial nursery standards, this 2.5-litre pot is specifically built for species that require a free-draining environment and high oxygen levels at the root zone.

How Anti Spiral Pots Work

In standard containers, roots often hit the smooth wall and begin to spiral, leading to girdling and poor plant stability. Anti Spiral Pots feature vertical ribs and air-flow points that redirect root tips. When these tips reach the air, they stop elongating (air pruning), which signals the plant to produce a dense network of lateral feeder roots. This process ensures the plant is ready for rapid establishment once transplanted.

Why Choose a 2.5L Anti Spiral Pot?

The 2.5-litre capacity and 185mm depth provide the ideal volume for plants with deeper root systems that need more time to mature before being moved to the field. Its free-draining design is particularly effective for sensitive species prone to root rot, ensuring a balanced moisture-to-oxygen ratio that traditional pots cannot match.

FAQs

What is an anti spiral pot?
An anti spiral pot is a container designed with internal ridges and air holes that prevent roots from circling, instead encouraging a more natural, branched root structure.

Why is drainage important for these pots?
The design promotes high oxygen levels, making it perfect for plants like orchids or native shrubs that are sensitive to waterlogging and require a free-draining environment.

What is the difference between the standard and SPF model?
While the standard 190mm pot provides excellent results, the P190SPF version features integrated feet to further lift the pot off the ground, maximizing airflow beneath the container.

Can these be used for trees?
Yes. They are specifically designed for starting trees and shrubs to ensure they develop a stable, non-spiralling root base before permanent planting.

Where are these pots made?
This 190mm 2.5L Anti Spiral Pot is proudly manufactured in Australia for professional horticultural use.
