How to dig out a yucca from the ground and transplant?

First of all, wear long sleeves, gloves, and eye protection when working with a yucca plant. The strappy leaves are slightly serrated and pointy, easily cutting hands and damaging eyes. Dig up a yucca like any other plant. Dig almost as far away from the "trunk" as the leaves reach. Use a sharp shovel and try to dig as deep as possible so that you don't disturb the roots any more than necessary. Fertilize and water well after replanting. Press firmly on soil to remove any air pockets which could lead to rot. Good luck!
