I have a concrete planter (round cup-shaped top, stem, square base.
Urn-like, I guess), that doesn't have a drain hole. Is it possible or
feasible to drill a drain hole from the bottom of the "cup" through the
stem, and out the bottom of the base? It might be 7" or so. Will it crack
the concrete? Any other ideas? Thanks!
P.S. We really need some type of drainage, as the flowers are stunted and a
heavy rain just filled the bowl!
