Long, narrow shovel. They’re sometimes sold as landscaper drain spade shovels. Transplanting spades are useful little tools that do just what you'd imagine: dig plants out of tight spots. The narrow blade (5-6" wide and 14-16" long) can slip between plants and get down deep enough to grab a good amount of roots, without disturbing the neighboring plants.
