One thing that I have done when I have a great pot that doesn't have a hole:
*drill a hole. Use a masonry bit and/or some masking tape to help with the drilling.
*place a nursery pot with your plant inside of the cool pot. The nursery pot will have holes and drain. If you need to disguise the cheap inside pot, use sphagnum or other moss. You can find moss in the woods, Walmart, craft store, or dollar store.
Where there's a will, there's a way!
