1. Choose a slightly larger pot. If you’re repotting your plant into a new pot, choose a pot that is 1-2 inches larger in diameter and 1 to 2 inches deeper than the plant’s current pot.
2. Choose a pot with drainage holes. When you’re selecting a new pot, make sure it has drainage holes to allow excess water to drain.
3. Cover the drainage holes. Cover the drainage holes with something that will allow water to pass through, like a paper towel or small-sized stone.
5. Put a few inches of soil in the new pot. You’ll need a base of soil under the plant so the roots have something to grow into. Don’t overfill the pot.
