What to use to block drainage holes in pots? The best ways to cover the drainage holes is to use something that doesn’t hold onto moisture. Something like a piece of cloth will hold onto moisture and it’s best you don’t use this to cover the hold. A better option would be a rock or a piece of gardening sheet that allows moisture to flow through freely.

What do you put in the bottom of a planter with drainage holes? Perlite is a soil amendment that improves drainage and encourages root growth.

Should I cover drainage holes in pots? Covering drainage holes in pots is a necessary evil. Without something to cover the hole in the bottom of your planter, the soil will eventually wash out of the pot through the hole in the planter and the plant will settle. This also means that your furniture will take a beating.
