Terracotta literally translates from Italian as ‘baked earth’. It’s a type of earthenware clay that's fired at high temperatures, resulting in a durable, porous material with its signature reddish-brown colour. The firing process creates tiny pores which allow the terracotta to absorb and release moisture – this is key to its weathering properties.

Generally, terracotta is less expensive upfront than many plastic alternatives, particularly brightly coloured ones. However, higher-quality terracotta pieces crafted by skilled artisans or those with a thicker glaze can command a premium price; it’s important to compare similar sizes and designs when considering the overall cost.

Unglazed terracotta is remarkably resistant to frost damage due to its porous nature, which allows water to escape. However, extreme temperature fluctuations can still cause hairline cracks, especially in thinner pieces – choosing a thicker-walled terracotta pot or carefully monitoring watering levels will help mitigate this.

Terracotta offers a more natural aesthetic and allows for better airflow around the plant roots, promoting healthier growth. Concrete is typically heavier, more durable in terms of structural integrity, and often cheaper; however, terracotta's breathability makes it a superior choice for many plants.

You can technically paint terracotta, but it’s not ideal. The porous nature of the clay means paint will often flake off over time, especially in damp conditions. If you do paint, use exterior acrylic paints and apply a sealant for added protection – consider that this will change the natural patina.

Clean terracotta with warm water and a soft brush to remove dirt and grime. Avoid harsh chemicals or abrasive cleaners, which can damage the surface. For stubborn stains, try a mild solution of bicarbonate of soda and water; always rinse thoroughly.

Terracotta will naturally lighten over time when exposed to prolonged sun exposure, developing its characteristic silver-grey patina – this is perfectly normal and adds to the material’s rustic charm. Glazed terracotta resists fading more effectively but may still show subtle changes.

Glazed terracotta offers superior water resistance, protecting your plants from root rot and reducing the need for frequent watering; however, it's less breathable and won’t develop a natural patina. Uglazed terracotta is more porous and allows for greater airflow, but requires more maintenance to prevent cracking.

Consider the mature size of your plants when choosing terracotta pots. Smaller pots are suitable for seedlings and small bedding plants, while larger pots – 30cm diameter or bigger – are needed for shrubs and perennials, ensuring adequate root space and stability.

Terracotta roofing tiles are almost exclusively made from a specific type of clay fired at high temperatures. The colour and texture vary depending on the clay source but generally, they're incredibly durable and provide excellent thermal mass to help regulate building temperature.
