The bald cypress is a deciduous conifer that produces “knee-like” lower trunks when grown in wet or swampy areas where it can grow up to 2 feet each year. Bald cypress trees grow best in USDA hardiness zones 5 through 10 where they will reach a height of up to 80 feet and a spread of up to 20 feet. Adequate water and fertilizer treatments will maintain the health of the bald cypress and stimulate fast growth.
Select a planting location for the bald cypress that offers a moist, acidic soil for best growth. The area should receive full sunlight to stimulate fast growth.
Test the soil pH to verify it is 6.8 or lower, as the bald cypress tree prefers this. Add ground rock sulfur to the soil based on the package application rate to lower the pH. Work the amendment to a depth of 10 inches and let the soil rest for two weeks.
Plant a one- or two-year-old bald cypress seedling tree in a hole dug to the same depth as the container it came in. Tamp the soil after planting the tree to eliminate air pockets around the roots.
Water the bald cypress tree after planting by soaking the soil to a depth of 10 inches. Continue to water the tree throughout the growing season when the soil surface begins to dry. Bald cypress trees grow quickly in a moist soil that is not overly dry or saturated with water.
Fertilize the bald cypress tree each spring with a balanced 10-10-10 fertilizer. Follow the package instructions for the application rate based on the size of the tree. Annual fertilizer treatments encourage tree growth.
