Choose a location in the landscape that is in partial shade and drains well. These plants will grow in full sun and full shade but does best in partial shade.
Dig a hole three times the diameter and the same depth of the container you purchased the shrub in. Clean the soil of all weeds and lawn grass. Mix in one part compost to three parts original soil.
Carefully remove the shrub from the container and gently spread out the roots with your hand. Set the shrub in the planting hole and fill the hole halfway with the amended soil. Water the soil to settle it around the roots. Continue to fill until the soil is level with the surrounding ground.
Saturate the soil immediately after planting. Then water every other day for two weeks while the roots are getting established. Once a week watering is normally sufficient throughout the growing season unless the weather is hot and dry, with no rain.
Apply a general purpose fertilizer once you start to see growth and each spring thereafter. Refer to manufacturer's directions on the amount to apply per size and age of the cypress.
Spread a 2-inch layer of organic mulch to the disturbed area of the soil. This will keep weeds from growing and help to retain moisture until the shrub starts to spread over the area.
