The soil requirements are not strict, neutral, calcareous soil, acidic soil and slightly alkaline soil can grow, and grow faster in warm and slightly dry areas. Resistant to trimming and easy to shape. It is often propagated by sowing seeds, and can also be planted and raised. The growth rate is moderate and slightly slower than that of cypress. It has a certain resistance to a variety of harmful gases and is a tree species with strong resistance to chlorine and hydrogen fluoride in coniferous trees. Resistance to sulfur dioxide is significantly better than that of oil pine. Common diseases include cypress pear rust, cypress apple rust and cypress heather rust.
