Plant the dwarf cypress in soil loosened and amended with generous amounts of organic matter. Dwarf cypress enjoy full sun, but don't tolerate a hot sun well. Transfer specimens grown from containers in fall or the spring. Water well until fully established.
Add mulch, such as pine needles or wood bark chips, around the base of the dwarf cypress to retain moisture and keep the soil cool, but keep mulch 6 inches away from the trunk. Dwarf cypress grow well in multiple regions, but thrive in areas with moist and cool summers and mild winters. Avoid planting dwarf cypress in regions with hot, humid summers or heavy soils. Never plant dwarf cypress in windy locations. Dwarf cypress best grow in the U.S. Department of Agriculture's hardiness zone 5.
Apply fertilizer to the dwarf cypress in the spring using a water-soluble, balanced slow-release fertilizer specially developed for evergreen shrubs. The fertilizer will typically be a 10-10-10 fertilizer. Follow the instructions on the package for dilution.
Water the dwarf cypress after the top inch of the soil becomes dry. Ensure the soil has good drainage.
