When selecting a new pot for your houseplant, choose one that is 2 to 3 inches larger in diameter than the pot it came in. This will give the plant space to grow, but not so much space that the soil becomes easily waterlogged. As far as what the pot should look like or what it should be made of, the world is your oyster. Go traditional with a classic terracotta pot or get artsy and transform old kitchenware into a quirky planter. For best results, the pot should have drainage holes in the bottom so that water can wash through the soil and out of the pot. Without proper drainage, water can get trapped in the bottom, turning the roots swampy and potentially leading to pests and disease. You will also need a saucer for your pot to collect the water that runs out the bottom. You can find terracotta and plastic versions at your local garden center, or you may choose to up the design element and go with a small ceramic plate or shallow bowl. The only rule is to select a saucer several inches larger than the base of your pot. A too-small saucer will result in muddy water all over your furniture.
