Air-Pot В®

The Air-Pot В® is an innovative growing system that has unequivocally revolutionised container grown production, solving the root-spiraling problem whilst actively enhancing the growth and health of plants.

How does the Air-Pot В® Work?

This system consists of a reusable plastic ‘sleeve’ manufactured from recycled plastic that surrounds the root system. When laid flat, the ‘sleeve’ resembles a honeycomb or an egg carton with small holes at the tips. The holes are always positioned on the outside of the container, and as the outward growing root tips extend to the boundaries of the Air-Pot В® , the cones funnel the roots towards the holes, meaning they dehydrate upon exposure to the air. This generates gentle pruning, as well as stimulated lateral root growth, producing a more fibrous root system whilst preventing root circling.

When growing trees in Air-Pot В® , each tree is placed on a layer of compost and tied to covered support wires, in such a way as to avoid damage to the stem whilst being held securely in place. The Air-Pot В® is then wrapped around the roots leaving an appropriate gap to fill with compost.

The compost is then firmed in to allow optimum root growth and each tree is regularly monitored to ensure correct watering and feeding. The tree is prepared for dispatch using a wire basket and hessian both of which will degrade away over time when planted, whilst the Air-Pot В® will be reused for several seasons at our nursery.

The main advantages at a glance:
  • A much improved fibrous root system offers better transplant resilience and no transplant shock
  • Plants grown in this way are available all year round
  • No waste products delivered to the client’s site
  • The trees are packaged as conventional rootball
  • Easy to anchor as the flat bottom of the Air-Pot В® gives greater stability
  • Simply to handle
  • Toughly constructed from recycled plastic so they can last up to ten years or more
  • Able to containerise any size tree or shrub

What Is An Air Pot – How Does Air Pruning Work

Air pruning roots is an effective way to promote root health in potted plants. If your plants in containers seem sickly, it may be due to any number of root problems caused by uneven or overgrown roots. Air pruning containers create a healthy and hands-free environment for roots that makes for a stronger plant and easier transplanting. Keep reading to learn about air pruning roots.

Air Pruning Roots

How does air pruning work? In nature, a plant’s roots can grow wherever they please. In a container, of course, there’s a firm border to their growth space. Because of this, the roots will butt up against the wall and often continue to grow along it, creating the root-bound spiral shape so common in potted plants.

The roots grow thick and intertwined, inhibiting nutrient and water access and possibly eventually strangling the plant.

Air pruning containers, however, stop the root’s growth at the wall of the container so that instead of wrapping around the wall, it sends out offshoots along its length, creating a stronger, more dispersed structure with many more root tips for accessing water and nutrients. This is the ideal root structure for potted plants.

What is an Air Pot?

An air pot promotes this healthy root structure with just what you’d expect: air. Plants don’t want their roots to grow above ground, so when a root encounters air, the plant stops its progress in that direction and concentrates its energy in other parts of the soil.

There are many different types of air pruning containers on the market, and some gardeners even make DIY air pruning pots, but the basic concept of all of them is letting in airflow on the sides and bottom of the container to stop root growth around the edges and promote it inside the soil.

  • Some air pruning containers have simple lines of holes along the edges. These are effective but not practical for fine potting material.
  • Some are made of fabric, and are suited to fine potting material but awkward for transplants.
  • Some are plastic grids surrounded by perforated sheets that actually require some assembly. These are very effective at air pruning roots and transplants, but are also not ideal for fine material.
