Blue Ice Cypress
Blue Ice Cypress (Cupressus arizonica var. glabra ‘Blue Ice’) is a striking evergreen conifer known for its dramatic silvery-blue foliage and strong vertical structure. With its dense, pyramidal form and finely textured needles, this fast-growing tree makes a bold statement in any landscape. Reaching heights of 20–30 feet and spreading 10–15 feet wide, Blue Ice Cypress is ideal as a specimen tree, privacy screen, or evergreen hedge. Its foliage retains its icy blue tone year-round, offering four-season visual interest and contrast against green plantings or darker evergreens.
This low-maintenance conifer thrives in full sun and well-drained soils and is remarkably heat and drought tolerant once established. Unlike many evergreens, Blue Ice Cypress performs well in hot, dry climates, making it an excellent choice for xeriscaping, windbreaks, or larger mixed borders in challenging environments. Its resistance to pests and diseases, combined with its architectural presence, makes it a favorite among landscape designers seeking color, texture, and form with minimal upkeep.
Whether planted in rows for a stunning privacy barrier or used individually as an eye-catching focal point, Blue Ice Cypress adds structure and elegance to residential and commercial landscapes alike. Its refined foliage, adaptability, and fast growth make it a valuable addition to any landscape plan looking for evergreen interest with a cool-toned twist. For year-round beauty and performance in sun-drenched sites, Blue Ice Cypress is a reliable and visually captivating choice.

How to Care for Blue Ice Cypress
Before you buy a Blue Ice Cypress, make sure to read about the recommended care instructions to keep this plant healthy and thriving.
How do I plant my Blue Ice Cypress Tree?
To plant your Blue Ice Cypress tree (Cupressus arizonica var. glabra ‘Blue Ice’), choose a location with full sun and well-drained soil to ensure optimal growth and foliage color. Begin by digging a hole twice as wide and just as deep as the root ball. Carefully remove the tree from its container or burlap wrap, gently loosen the roots, and place the tree in the hole so the top of the root ball is level with the surrounding soil. Backfill with native soil, gently tamp down to eliminate air pockets, and water thoroughly to help settle the roots. Space multiple trees 10–15 feet apart if planting as a privacy screen or windbreak. After planting, apply a 2–3 inch layer of mulch around the base of the tree, keeping it a few inches away from the trunk to prevent rot. Mulching helps retain moisture and regulate soil temperature, especially during the establishment phase. Water deeply once or twice a week during the first growing season to promote strong root development. Once established, Blue Ice Cypress is highly drought tolerant and low maintenance, making it an ideal choice for sunny landscapes, dry slopes, or large-scale plantings where year-round privacy and striking blue foliage are desired.
How should I water my Blue Ice Cypress Trees?
Watering your Blue Ice Cypress tree correctly is essential during its first year to ensure successful establishment and long-term health. After planting, water deeply once or twice a week, depending on rainfall and soil type, to keep the root zone consistently moist but not waterlogged. Use a slow, deep soak method—such as a soaker hose or drip irrigation—to encourage deep root growth and prevent shallow rooting. Mulching around the base of the tree with 2–3 inches of organic mulch will help conserve soil moisture and reduce the frequency of watering. Once established, Blue Ice Cypress trees become highly drought tolerant and typically require only occasional deep watering during extended dry periods. In hot or arid climates, monitor soil moisture every few weeks and water as needed to prevent stress. Avoid frequent shallow watering, which can lead to weak root systems and poor drought resistance. With the right watering habits, your Blue Ice Cypress will thrive in full sun and dry, well-drained soil, providing beautiful, silvery-blue foliage and strong evergreen structure throughout the year.
How Should I fertilize My Blue Ice Cypress Tree?
Fertilizing your Blue Ice Cypress tree helps promote healthy growth, vibrant blue foliage, and strong root development. In early spring, apply a balanced slow-release fertilizer, such as a 10-10-10 or 12-6-8 formula, around the tree’s drip line, avoiding direct contact with the trunk. For young trees, a light feeding once a year is typically sufficient. If your soil is sandy or lacks organic matter, you can incorporate compost or well-rotted manure to improve nutrient availability and overall soil health. Always water thoroughly after applying fertilizer to help it penetrate the soil and reach the roots. Mature Blue Ice Cypress trees are relatively low-maintenance and may only need fertilizing every couple of years if they’re growing in fertile, well-drained soil. Avoid over-fertilizing, as excessive nitrogen can lead to overly rapid growth that may weaken the tree’s structure. If foliage begins to yellow or growth slows, a soil test can help identify nutrient deficiencies and guide your fertilizer choice. With the right fertilization routine, your Blue Ice Cypress will thrive as a striking evergreen specimen or privacy screen, offering year-round color and texture to sunny, well-drained landscapes.

How and When Should I Prune My Blue Ice Cypress Trees?
Pruning your Blue Ice Cypress tree should be done in late winter to early spring, just before new growth begins. This timing allows you to shape the tree and remove any dead, damaged, or crossing branches without interrupting the plant’s natural growth cycle. Use clean, sharp pruning shears or loppers to make precise cuts just outside the branch collar, being careful not to remove the central leader if maintaining a pyramidal shape. Light annual pruning can help control size and encourage denser, more uniform growth, especially when the tree is used as a hedge or screen. Avoid heavy pruning into old wood, as Blue Ice Cypress does not regenerate well from bare branches and may not produce new growth from deeply cut areas. Instead, focus on light shaping and removing only what is necessary to maintain the desired form and promote airflow. For established trees, periodic maintenance pruning every 1–2 years is often sufficient. With proper and timely pruning, your Blue Ice Cypress will maintain its elegant silvery-blue foliage and dense evergreen structure, making it a long-lasting focal point or privacy solution in full-sun landscapes.
