What You'll Learn
Incense cedar trees are native to California and Oregon
The incense cedar tree, or Calocedrus decurrens, is a species of conifer native to western North America, with most of its range in the United States, from southwestern Oregon through most of California, and a small part of western Nevada. In Oregon, it is found in the central southwestern part of the state, while in California, it is native to the northern part of the state, as well as the Klamath National Forest in Siskiyou County. It is also found in a small area of northwest Mexico in northern Baja California.
The incense cedar is an evergreen tree with glossy, bright green foliage and a pyramidal growth habit. It is known for its distinctive J-shaped branches and spicy pencil fragrance. The tree is adaptable to a variety of growing conditions, from wet to dry, and will grow quickly in sunny, moist areas. It is also one of the most fire- and drought-tolerant plants in California.
The bark of the incense cedar is thick, pinkish-orange, and spongy on old trees. The aromatic wood has been used for a variety of purposes, including window sashes, exterior siding, trellises, fencing, paneling, and decking. It is also used to make pencils, as the wood is soft, light, and sharpens easily without splintering. The Indigenous peoples of California have also used the incense cedar in traditional medicine, basket-making, hunting bows, and building materials.
The incense cedar is a large tree, typically reaching heights of 30-40 meters (100-130 feet) and a trunk diameter of up to 10 feet. The largest known specimen, located in Klamath National Forest, California, is almost 48 meters (157 feet) tall with a trunk circumference of 12 meters (39 feet). These trees can live for over 500 years and are easy to grow in gardens but require plenty of room.

They are adaptable to a variety of growing conditions
The incense cedar tree is native to northern California, Oregon, and other western states. It is well-adapted to a variety of growing conditions, from wet to dry, and can tolerate both full sun and partial shade. It is a slow-growing tree that will eventually grow into a tall coniferous tree, typically reaching heights of 25 to 40 feet in urban environments, though some specimens can reach 70 to 80 feet.
The tree is well-suited to smaller yard spaces due to its narrow growth habit. It prefers moist, fertile, and well-drained soils but can tolerate poor soils and a range of soil types, including sand, loam, clay, and calcareous soil. It also adapts well to different exposure conditions, including frost and fog, and can grow in a range of elevations.
While the incense cedar tree is hardy and adaptable, it does have some specific care requirements. It needs regular irrigation for the first few years until it becomes established. After that, watering once per week is generally sufficient, with deeper watering in the summer and less in the fall, spring, and winter.
In terms of planting, the incense cedar tree is best planted in the fall through the spring and pruned in late fall to winter. It typically requires little pruning, but if the main growth leader breaks or dies, it is important to choose a single new leader from the new growth and remove the others to avoid competition.

Incense cedars can grow to be 150 feet tall in the wild
The incense cedar, a coniferous tree native to California and Oregon, can grow to be 150 feet tall in the wild. However, in landscapes, it usually reaches heights of up to 100 feet, and in urban environments, it typically falls within the range of 25 to 40 feet. The tree is adaptable to various growing conditions, from wet to dry, and thrives in sunny, moist areas. It prefers well-drained, slightly acidic soil and can tolerate partial shade.
The incense cedar is a slow-growing plant, and its height can be managed through pruning. While it does not require frequent pruning as it grows, established trees can benefit from occasional deep watering if the soil is particularly dry. The tree's unique silhouette, with its columnar form and billowy fans of evergreen scales, makes it an attractive landscape tree. Its spicy, pleasant scent and dense, billowy canopy also contribute to its appeal.
The incense cedar is known for its drought tolerance, which is due to its ability to close its stomata to prevent water loss. However, young incense cedars need regular supplemental water for the first few years after planting to establish themselves. They are also susceptible to certain diseases, such as canker diseases, which are fungal infections that affect the branches. Root diseases can also impact the health of the tree, causing browning from the bottom up.
The incense cedar's aromatic wood has been used in various applications, including the manufacturing of pencils due to its softness and ease of sharpening. Its water-resistant properties make it suitable for window sashes, exterior siding, trellises, and other outdoor uses. Overall, the incense cedar, with its potential to reach impressive heights, is a striking and adaptable tree that can enhance any landscape.

The trees are resistant to decay, except for pocket dry rot
The incense cedar tree, also known as Calocedrus decurrens, is a beautiful evergreen conifer native to parts of Oregon and California. With its lush, pyramidal growth habit and glossy, bright green foliage, it makes for a lovely addition to any yard or garden. Apart from its aesthetic appeal, the incense cedar tree is also known for its aromatic, fine-grained wood, which is resistant to decay and insects.
However, despite its overall resilience, the incense cedar tree is susceptible to a specific type of rot known as pocket dry rot. This fungus causes significant internal decay, compromising the structural integrity of the tree. While healthy bark provides a protective barrier against fungal colonization, knots and damaged areas can leave the tree vulnerable to infection.
Pocket dry rot primarily affects incense cedar trees that grow in favorable sites. For example, some stands in the Sierra Nevadas exhibit 100% colonization of mature specimens. This fungus can cause extensive damage to the tree's internal structure, leading to potential safety concerns if the tree is located near buildings or other structures.
To prevent and manage pocket dry rot, it is important to maintain the health of the incense cedar tree. Regular irrigation, especially during the first few years of establishment, can promote healthy bark development and reduce vulnerability to fungal infections. Proper pruning and wound management can also help minimize the risk of infection by limiting access points for the fungus.
While incense cedar trees are generally resistant to decay, pocket dry rot can pose a significant threat to their structural integrity. By understanding this vulnerability and implementing proper care and maintenance practices, homeowners and gardeners can help protect these beautiful trees and ensure their longevity.

Incense cedar trees are susceptible to canker diseases
Incense cedar trees, also known as Calocedrus decurrens, are native to Oregon and California and are known for their lush, pyramidal growth habit and glossy, bright green foliage. While these trees are adaptable to a range of growing conditions, they are susceptible to canker diseases, particularly when grown in poor sites or under stressful conditions.
Canker diseases in incense cedar trees are caused by various fungi, including Phaeobotryon cupressi, Diplodia sp., and Seiridium sp. These fungi infect the trees, leading to branch dieback and canker lesions. The cankers are sunken and constricting, with a distinct line between the necrotic and healthy tissue at the canker margin. The disease progresses slowly, resulting in significant branch loss over several years, and can affect both older and younger trees.
Incense cedar trees weakened by drought, root damage, or other sources of chronic stress are more susceptible to canker infections. The spores produced in the cankers can spread via water splash to healthy tissues, initiating new infections. While the trees do not usually die from this disease, their aesthetic value is significantly reduced due to the extensive branch loss.
To manage canker diseases in incense cedar trees, growers must be vigilant and aware of the issues in their landscapes and forests. Early detection is crucial, as some problems may not be easily noticeable in the nursery but can become more significant once the trees are installed in the landscape. However, it is unknown if any chemical treatments can effectively protect the trees from the spread of canker diseases.
