Susan is correct in saying Cym's should not be planted in wooden slat boxes. However there is no reason why you cannot hang your cym as long as you plant it in the correct pot.
Since you are in Florida you much be certain your cym is a warm growing type and since you want to hang it, it should also be a pendulous type (spikes hang down rather than grow up)
If your pot is plastic you can drill three or four holes around the top edge and attach cords for hanging. If you are crafty, you could make a macrame hanger for it. If your pot is ceramic or glass you need to drill holes in the bottom for drainage. You can purchase a ceramic/glass drill bit at any hardware store. Ask them how to drill in ceramic or glass, it does take some special care or you will break out the bottom of the pot. I would not recommend using a clay pot for hanging unless it is of the proper size. Remember, cyms need to be in a deep pot, at least twice the depth of the top width.
After you have your plant in the proper pot and have devised a way to hang it perhaps you can wrap the pot in sphagum, or better yet, since you are in Florida, use spanish moss.
I hope this helps, if not message me and we will try to work something out. It can be done, we just have to figure out how. LOL
