I received a handsome metal Tuteur and pot that are meant to be an emsemble. Thing is, the pot has no drainage hole. Seems odd to retrofit. Suggestions?

Just drill some drain holes, or find a handyman who could do it for you very quickly, and probably at no cost. We do it to all of the pots I find without drain holes.

If you don't want to drill holes but want to put a plant in it, have the plant in a separate pot with drainage holes and set that inside the other one. If too much water may drain out into the outer pot then you can raise the inner one slightly with pot feet.
