Makeshift metal container for herbs
I'm new here to this board (and a pretty new gardener). I have some metal containers that I would like to turn into herb pots. They are from Crate & Barrel, you can see a photo of it at the link below.
How should I prepare the container for planting my herbs? Do I need to drill holes in the bottom, add rocks or anything to the bottom for drainage? Should I be concerned about any chemicals that may be present? How about soil recommendations?
Thanks in advance.
