I am probably the only person in the world that is happy the holes are gone.
Our summers have become hot and dry. I would have to drag the hose around every day to water those huge pots if they had holes. If it rains we were getting short showers which barely watered the pots. I still had to drag the hose out at least once a week. The bottoms of the pots have styrofoam or leaves and the plant roots do not go down that far because the pots are so big so the soil would stay moist and the plants do not drown.
In my big pots I am growing mostly plants that want as much water as possible. Cannas, you can even grow in a pond, Brugmansia they seem to cannot get enough water. So the no holes are a good idea for me.
