Terracotta planters are unglazed clay pots known for their porous nature, which promotes excellent soil aeration and drainage. They’re ideal for plants that prefer dry conditions and are susceptible to root rot. Terracotta pots require regular watering, can develop a patina over time and may need sealing in cold climates to prevent cracking.
As a horticulturist with over two decades of experience in container gardening, I’m thrilled to share my insights on terracotta planters. These timeless clay pots have been a gardener’s favorite for centuries, offering both functionality and aesthetic appeal.
