Why Gardeners Swear by Terracotta Pots—and You Should Too

People have been using terracotta planters in their gardens for centuries, and why not? Terracotta containers are versatile, breathable, and decorative, providing an excellent home for all of your potted plants. To learn just what makes these containers so popular, we consulted gardening experts who shared their reasons for using terracotta planters.

Breathability

Terracotta containers are often appreciated for their breathability, which can keep plants healthier because air flow isn't restricted. "The porous clay allows roots to breathe, which helps prevent overwatering and root rot," says master gardener Angela Judd. "Unlike grow bags (which also allow roots to breathe), they don’t dry out as quickly, which is especially helpful in a hot, dry climate."

Moisture Regulation

Hand-in-hand with breathability is terracotta's ability to regulate moisture for plants, preventing waterlogging and fungal diseases. Author Lorraine Ballato suggests using terracotta for plants that like to be kept on the dry side. Judd agrees. "Terracotta is ideal for Mediterranean herbs like rosemary, thyme, oregano, and lavender; they can rot if the soil stays too wet," she says.

Temperature Insulation

While terracotta containers are vulnerable to cracking when temperatures drop below freezing, they provide insulation from both cold and hot weather, as long as the temperatures aren't too extreme.

Traditional Aesthetic

Choosing a container for your plants is primarily about practicality, but there is also an aesthetic interest. There's something timeless about terracotta planters and the traditional ambience they add to the garden. "Terracotta pots are hands-down my favorite," says Judd. "They're simple, classic, and so effective."

Landscape designer Jan Johnsen points out that terracotta planters look good solo or grouped in clusters. "Their warm, earthy color fits anywhere—in apartments, on lush balconies, or in rustic gardens. And they add a touch of old-world charm," she says.

Substance and Stability

Unlike lighter containers, such as plastic, that may not hold up against wind, terracotta pots have weight and substance. "I love that terracotta pots are heavy enough to stay put in the wind, and they develop a beautiful natural patina over time," says Judd. 

Environmentally Friendly

If you're looking for a sustainable choice for your garden, terracotta fits the bill. "Made from natural clay and fired without glazes or chemicals, terracotta planters are fully biodegradable," says Johnsen. "In short, they are stylish, breathable, eco-friendly, and they only get better with age."

Considerations for Planting in Terracotta 

For all of their advantages, terracotta pots aren't without their downsides. "Their biggest flaw is that they can't take freezing temperatures," says Ballato. "You must consider them temporary or take other steps if your garden is in a cold zone where temperatures go below 32 degrees Fahrenheit."

Because soil dries out faster in a terracotta container, it's important to choose plants that thrive in well-draining soil. "I wouldn't use them for plants that like moisture, like angel's trumpet or even roses," says Ballato. Closely monitor the soil moisture and water more frequently if needed.

That said, if you love the look of terracotta containers and want to pot thirstier plants in them, Judd recommends pairing a terracotta pot with a terracotta olla. "The combination provides consistent moisture right at the roots, without overwatering," she says.
