Let’s learn about terracotta pots and how using them provides the most benefits.
About Terracotta Pots
Terracotta plant pots get their rusty tinged hue from the type of clay that is used to fire them. The color seems to provide a perfect foil for many types of flowers and foliage. It is this unmistakable hue that easily identifies a terracotta clay pot. The containers are plentiful, affordable, durable, and come in many different sizes and shapes. They are suitable for numerous varieties of plants. The name terracotta comes from the Latin “baked earth.” The body has a natural orange brown hue and is porous. The clay material is fired, and during the process the heat releases iron which causes the orange hue. The resulting terracotta is not watertight, and the pot can actually breathe. Sometimes it is glazed to reduce the porosity, but most plant containers are unglazed and in a natural state. Terracotta through the ages has been used in roof tiles, plumbing, art, and much more.
When to Use Terracotta
Using terracotta pots is mostly a personal choice; however, they do have some differences when related to plastic or other types of planter materials. Since a terracotta clay pot is porous, it allows excess moisture to evaporate, helping to keep plant roots from drowning. The material also allows air to penetrate to the soil and roots. Clay pots have thick walls which can insulate the plant from extreme temperature changes. Gardeners who are heavy handed with watering benefit from growing in terracotta, as the porosity of the clay allows all that excess moisture to wick away from plant roots. On the downside, that very evaporative property is bad for plants that like moist soil.
What Not to Grow in Terracotta
Not every plant will benefit from terracotta material. It is heavy, cracks easily, and gets a white crusty film over time. However, for plants such as succulents and cacti, it is an excellent container. Since the planters dry out quickly, plants that are in full sun may become too dry. The material isn’t good for seedlings or plants like some ferns, which need consistently moist soil. Today’s plastic pots come in many shapes and colors, and even some that resemble traditional terracotta. They are suitable for most plants, lightweight, and durable. However, they hold moisture and can cause root rot. As you can see, neither material is a perfect solution. Which you choose is a matter of preference and experience.
