Putting rocks in the bottom of a planter is a bit of a hot topic in the houseplant world.

She notes that salt builds up in this water and creates an overall toxic environment for the roots.

This is also why you should empty any standing water in your plant’s saucers.

If that’s the case, there are workarounds you might try.

This is especially easy if your planter is made from wood or plastic because any drill bit will work.

However, drilling through metal pots requires a cobalt drill bit.

As far as drilling a ceramic pot goes, the process is just a bit more involved.

We recommend drilling just one large hole in the middle instead of several smaller holes.

If a container is extra special to you, try out one of the following methods instead.

Simply plant your houseplant in a pot with a drainage hole that is slightly smaller than your decorative pot.

Then, place it inside the decorative pot.

Just be sure to remove it from the decorative pot when you water it.

Place it back inside after all the water has drained out.
