Training Pots - Drainage Colanders (6-3/4” wide)

Accelerate root development and build healthier bonsai with Training Pots – Drainage Colanders. Designed with exceptional airflow and drainage, these colanders encourage air pruning, producing a dense network of fine feeder roots that are essential for vigorous growth, improved nutrient uptake, and successful future transitions into bonsai pots.

Unlike traditional nursery containers, drainage colanders allow excess water to escape quickly while exposing root tips to air. As the roots reach the edge of the container, they naturally air prune, stimulating the tree to produce more fine roots throughout the root ball rather than a few long circling roots. The result is a stronger, more compact root system that supports faster trunk development and healthier trees.

Measuring 6-3/4" wide, this size is ideal for young bonsai, rooted cuttings, seedlings, pre-bonsai, and recently collected material beginning its development journey.
