Question: How often should trees be replaced in a Filterra system?
Answer: The trees and plants in a Filterra bioretention system do not need to be replaced on a fixed schedule. With proper species selection and maintenance, trees can last 10–20+ years.
They should only be replaced when they show signs of disease, pest infestation, or decline that cannot be treated. For a complete list of recommended plants, please visit https://www.conteches.com/technical-guides/search/?filter=OOIA4XCWXG
