Terracotta is a clay-based ceramic material that is non-vitreous, meaning it lacks the impermeability to water achieved through vitrification during the firing stage of pottery and ceramics. Terracotta can be either glazed (making it waterproof) or unglazed and has a rich history of use by humans spanning thousands of years.
The benefits of using terracotta pots can be distilled into its non-vitreous nature, which makes it an exceptionally porous material. This porosity leads to several functional advantages when potting plants in terracotta containers.
1. Excellent Water Absorption:
Terracotta readily absorbs water, making it an excellent choice for plants that thrive in dry soil conditions. This quality also helps prevent issues like root rot, often caused by overwatering. Plants such as cacti, succulents, snake plants, and others benefit from terracotta pots. The visible absorption of water into the porous material makes it easy to determine when a plant needs watering. The water lines on the terracotta surface indicate the moisture level in the soil, making it ideal for plants with different moisture requirements.
2. Enhanced Breathability:
Terracotta's porous nature allows it to "breathe," permitting the easy passage of air and particles. This feature contributes to soil health and aids in disease prevention among plants.
3. Eco-Friendly Choice:
For those seeking an environmentally friendly potting option, terracotta is an ideal choice. As a natural, clay-based material, terracotta is 100% biodegradable. Additionally, broken terracotta pots can be upcycled to create decorative planters, succulent container gardens, fairy gardens, and more.
4. Aesthetic Appeal:
Aged terracotta pots have a rustic and appealing appearance. While some stores sell artificially aged versions, natural aging occurs quickly, especially in areas with hard water. Mineral deposits from the water may become visible on the pot's surface after a few weeks of regular watering. If white, mold-like deposits appear on the pot's exterior, rest assured it won't harm the plant. Reducing watering slightly usually resolves the issue, or you can simply wipe off the deposits with a paper or dry towel.
5. Cost-Effective:
Terracotta pots are very affordable, with prices as low as $1.00 or even less for standard-sized pots. This cost-effectiveness makes them a practical choice when compared to pricier decorative planters.
6. Versatile in Shape and Size:
Terracotta pots come in a variety of shapes, styles, and sizes, offering options to suit various preferences. Styles like the "European style" pot exude a minimal and rustic aesthetic and can be found at retailers like IKEA. These pots come in a wide range of sizes, from small one-inch containers to large planters several feet in diameter, providing ample choices. They are readily available at numerous retail locations.
7. Plants That Thrive in Terracotta Pots:
While any plant can technically grow in terracotta pots, some may require more attention due to the material's water-absorbing properties. Moisture-loving plants can flourish in terracotta but will need more frequent watering. In contrast, plants that prefer consistently dry soil thrive in terracotta pots. Examples of such plants include cacti, succulents, snake plants, hoya, Mediterranean herbs, ZZ plants, and many others.
