Should you cover the 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.
What do you put at the bottom of a planter for drainage? If you’re planting in large containers, you can use a layer of plastic bottles at the bottom to help fill them up. The bottles should be empty, but not crushed, and have the caps on them. You can use water bottles or half-gallon jugs.
Can you put paper towel at the bottom of a potted plant? In a pinch I’ve even used a paper towel. I fill up the container, plant it, water it well, wait a day or two and then go back and poke a hole in the paper towel or coffee filter from the bottom. By this time the soil isn’t going to fall out and there will be nothing to impede drainage.
How do you seal holes in plastic pots?
- Place some tape over the bottom of the hole. When it comes to filling the hole, this will ensure nothing will splurge out on the other side.
- Apply sealant. What’s so great about sealant is that it’s waterproof.
- Leave to dry overnight and then peel off the tape on the bottom side of the pot.
