Root manipulation
There is a growing number of manufacturers who produce containers specially designed to reduce root defects. The container shown above reduces circling by pruning roots along the sides and bottom of the root ball using holes designed to allow air into the media. The air holes can be seen along the sides of the container. No system is 100% effective at eliminating circling roots but most systems reduce circling dramatically. This reduction in circling roots improves quality.
