Air Root pruning
Air root pruning is a technique that encourages the development of a dense, fibrous root system in plants.
It involves exposing the roots to air, which causes the root tips to dry out and die. This trigges the plant to produce new, finer roots, resulting in a more robust and efficient root system.
Major early developments in container design were the addition of basal air root-pruning (1b) and addition of verti- cal root-training ribs (2). The most
recent designs incorporate side slots for lateral air root-pruning (3). Container design has also evolved from the long thin shape (SA:D ≤ 1.0) to more squat
shapes (SA:D ≥ 1.5).
Benefits of Air Root Pruning:
Improved nutrient and water uptake: A denser root system can absorb more nutrients and water from the soil, leading to healthier and more vigorous plants.
Increased resistance to stress: Plants with well-developed root systems are better able to withstand drought, heat stress, and other environmental challenges.
Enhanced transplant success: Air-pruned plants transplant more easily, as their roots are less likely to be damaged during the process.
Reduced root circling: Air pruning helps prevent roots from circling the pot, which can restrict growth and make transplanting difficult.
How to Air Prune:
Choose the right container: Use a breathable container, such as a container with slots in the sides, to allow air to reach the roots.
Plant your plant: Plant your plant in the container.
Place the tray: Use a benching system that allows air flow under the tray. normaly more than 300 mm above the ground
Monitor and adjust: As the plant grows, monitor the root system and adjust the growing conditions as needed.
Tips for Successful Air Root Pruning:
Start with healthy plants: Use healthy, disease-free plants for air pruning.
Provide adequate drainage: Ensure that the container has good drainage to prevent waterlogging.
Maintain proper watering: Water your plants regularly, but avoid overwatering.
Fertilize regularly: Fertilize your plants with a balanced fertilizer to promote healthy growth.
Air root pruning is a simple and effective technique that can benefit a wide range of plants, from vegetables and herbs to trees and shrubs. By following these tips, you can help your plants develop strong, healthy root systems and thrive.
