Evolution of plant production in containers©

C.E. Whitcomb
This paper highlights some of the historical research that led to containers that can improve the root system, rather than just acting as root packaging. Prior to 1968, plant containers, which had once been metal cans, were mainly smooth, injection-molded, plastic pots that created circling, congested roots. To this day, many nurseries fail to provide their customers with root systems without these problems.
