[header] How to edge a flower bed [title] Start by removing existing edging material, if there is any. [step] If there are borders around your flower bed made of plastic, metal, or some other material and you no longer want to use them, pull them carefully out of the ground. Discard this old material. 
[substeps] If you cannot pull this up by hand, try working a small hand trowel or pry bar under the bottom edge and levering it out. Sometimes the edging is anchored with stakes, so be sure to remove them first.
