Q: I bought a half-barrel to use as a planter, but it doesn’t have drainage holes. Do I need holes in the pot, or can I just add some gravel to the bottom for drainage?
A: If you think you might use the pot for some other purpose in the future that will need to hold water, I would not add the holes. Otherwise, you should definitely drill the holes. Gravel in the bottom of a pot does not help the drainage.
