Perfect training pots for the serious enthusiast and ideal all round growing pots, with multiple advantages over traditional plastic pots.
The design of the pot, not only offers air-pruning technology, to reduced root circling and increase feeder-root mass, it also aids in drainage and air-circulation. Healthier roots mean healthier trees.
The potential to ‘guy wire’ rather than wire branches has many advantages, such as less chance of causing wire damage or knocking off almost invisible new buds.

Plant roots absorb most of the water and nutrients in the area closely behind the root tip. By air pruning the roots develop more branches and therefore more active root tips. The overall absorption surface increases significantly. In addition, the spatial structure of the roots improves.
In normal pots it can occur that 80-90% of the root tips are located in a relatively thin layer (6-12) directly at the pot wall. In air pruning pots the new tips grow evenly distributed throughout the entire substrate. The effects being:
- More intensive absorption of water and nutrients, less fertilizer is leached out of the pot,
- Trees are more resistant to temperature extremes as the roots in the centre of the root ball are better isolated
- Higher stress resistance e.g. against drought stress
- Increased overall growth of the plants.
There are numerous scientific studies about how much the growth of different plants is increased by this technique. The results vary due to the different species that were examined and due to different setups of the experiments. In most cases the acceleration was in a low double-digit percentage range.
When you repot roots that grew in a normal pot you always have to cut off overlong circling roots. As a result, you often have to remove a significant part of the root mass.
In air pruning pots there are no/less circling roots. If you loosen up the roots you find a root ball that is hardly bigger than the pot. How much of this you prune during repotting is up to you. This is especially favourable when trees are moved from training pots into bonsai pots.
