How to improve drainage in a container?

The best strategy to improve drainage is twofold. First, choose potting soils that consist of coarse-fibred peat moss combined with a high percentage of perlite. Perlite is that white, lightweight rock common in high-quality potting soils. Because perlite is blended into the mixture, it will increase drainage. High-quality, well-drained potting soils for interior use are about 70 percent coarse-fibred peat moss and 30 percent perlite.

Drilling small holes along the sides will allow the pot to have more outlets to release drainage.
