Is the pot made out of something you can drill some drain holes into?

plastic. The other pots did okay. for some reason this one got the worst of it. My 18 inch pot has no water sloshing in the bottom.

All pots need drainage holes or your plants will die from suffocation. They need air that can be drawn up from the bottom through the soil (and the holes providing for drainage) as much as water and fertilizer.

I think I'd remove the plants, soil and all, and drill a couple of holes right at the bottom of the pots on the sides. Then you can replant them and know they won't drown and die.

I would drill a nice size hole at the bottom of the container, about a 3/8- 1/2 wide, take an old t-shirt and tear a nice long narrow piece from it and stick it up in that hole about 6 inches with a pencil. This will trick the perched water to drain down the fabric and out of the pot. I use this kind of wick in all my pots, it works great for draining that darn perched water.

You are not going to believe this but I left saturday with water in the pot intending to take care of it when I got home this afternoon. To my surprise the 2 plants that currently share the pot (getting another one soon hopefully) sucked up all the water on the bottom of the pot. I even checked to make sure it wasn't frozen down there because we've had freezing cold weather and sure enough the bottom of the pot is just as warm as the rest of it. Thirsty little buggers.
