Scope. Weed control can be one of the most costly risks in the production of container-grown nursery crops. Any control program begins with the correct identification of the weeds present, along with an understanding of their life cycles and modes of reproduction and spread. Treated here are the most common weeds of outdoor container nurseries, as well as a selection of recently introduced species with the potential to spread. This work is based in large part on Weeds of Container Nurseries (Neal & Derr 2005), but builds on that treatment through the addition of multi-access keys, taxa, and images. The content is optimized for mobile use and should be accessible from standard browsers on nearly any device, whether desktop, tablet, or smartphone.

Future. We consider this work a "living" resource and seek to continue to add images, tweak content, improve keys, etc. over time. Future versions will be identified by sequentially increasing version numbers.
