While many plants will benefit from the improved air circulation and faster moisture evaporation in terracotta pots, not all plants are suitable for these conditions.
Terracotta, which is made from natural, unglazed clay, may be the single most popular material for plant pots. There are many perks to growing plants in terracotta pots, and they’re perfect for indoor and outdoor container gardens. However, some plants are more suited to growing in clay pots than others. Here are some of the best plants to grow in terracotta, the ones to avoid, and an overview of why terracotta is so great for your plants.Do Plants Grow Better in Terracotta Pots?
The porous nature of terracotta allows excess moisture to evaporate through the pot, which helps prevent complications from overwatering. It’s great for chillier, shadier regions, where it takes longer for soil moisture to evaporate. The risk of root rot is diminished, which is especially useful because root rot is notoriously difficult to treat! The warm, rusty brown color is on the lighter side of the spectrum, so it doesn’t absorb as much heat as dark-colored containers. Plus, it’s just a lovely natural shade that’s easy to incorporate into most color palettes. While many plants will benefit from the improved air circulation and faster moisture evaporation in terracotta pots, not all plants are suitable for these conditions. Varieties that need consistently moist soil will be hard to keep happy in terracotta, and you’ll need to water much more frequently.Choosing the Best Terracotta Pots for Your Plants
The quality of your terracotta makes a big difference in the durability of your pots. Cheap terracotta is prone to cracking, but you can expect the good stuff to last for decades. To test the quality of your pot, place it upside down on a flat, hard surface, and tap on the edge of its base with a metal knife. If it makes a thud, it’s a dud. If it makes a resonant ringing sound, you’ve got a good one! The best terracotta usually comes from Italy, so checking the label to see its country of origin is also a good indicator of quality.These Are the Best Plants for Terracotta Pots
