Maintaining a tiered terracotta falls feature involves regular care and protection. Ensure the terracotta pots are of high quality and frost-resistant if you live in colder climates to prevent cracking. Regularly check for leaks and repair them promptly. Keep the water clean by using an appropriate filtration system and treating it with non-toxic solutions to prevent algae growth. During the winter, protect the feature from freezing temperatures or drain the water to avoid damage. Additionally, inspect the pump and electrical components periodically to guarantee smooth operation. Proper maintenance will ensure the longevity and allure of your tiered terracotta falls.
