White Cedar (Thuja occidentalis)

White Cedar, scientifically known as Thuja occidentalis, is a popular evergreen tree that is widely used in landscaping in Aurora, Ontario, and the Greater Toronto Area. This tree is native to North America and is highly valued for its numerous benefits, including its attractive foliage, low maintenance requirements, and adaptability to various soil and weather conditions.


Advantages of Using White Cedar in Landscaping

  1. Privacy Screening: White Cedar is an excellent choice for privacy screening as it can grow up to 50 feet tall and form a dense, compact barrier that effectively blocks noise and visual disturbances from the surrounding area.

  2. Low Maintenance: White Cedar is a low-maintenance tree that requires little care beyond regular watering and occasional pruning. It is also resistant to pests and diseases, making it a durable and long-lasting addition to any landscape.

  3. Attractive Foliage: White Cedar has a soft, feathery foliage that is a bright green color in the summer and turns bronze or reddish-brown in the fall. The tree's branches also have an interesting texture that adds depth and character to any landscape.

  4. Environmental Benefits: White Cedar is a native species that provides numerous environmental benefits, including air purification, erosion control, and wildlife habitat.


Watering White Cedar

Watering is critical to the survival and health of White Cedar trees, especially during the first few years after planting. Here are some tips on how to water White Cedar trees properly:

  1. Deep Watering: White Cedar trees have a deep root system, so it is essential to water deeply to ensure that the water reaches the roots. The soil around the tree should be soaked to a depth of 6 to 8 inches.

  2. Frequency: Young White Cedar trees require frequent watering, especially during the summer months when the weather is hot and dry. Water the tree at least once a week or more if the soil is dry to the touch.

  3. Time of Day: The best time to water White Cedar trees is in the early morning or late afternoon when the weather is cooler. Avoid watering in the middle of the day when the sun is hottest, as the water will evaporate quickly, and the tree may suffer from heat stress.


Maintenance Protocol

To maintain the health and beauty of your White Cedar trees, it is essential to follow a regular maintenance protocol. Here are some tips on how to care for your White Cedar trees:

  1. Pruning: White Cedar trees require minimal pruning, but it is still necessary to remove dead or damaged branches and maintain the tree's shape. Prune the tree in late winter or early spring before new growth appears.

  2. Fertilizing: White Cedar trees do not require regular fertilization, but you can apply a slow-release fertilizer in the spring to help the tree establish strong roots.

  3. Mulching: Mulching around the base of the tree can help retain moisture in the soil, prevent weed growth, and regulate soil temperature. Apply a 2 to 3-inch layer of mulch around the base of the tree, making sure not to pile it against the trunk.



White Cedar trees are a great choice for landscaping in Aurora, Ontario, and the Greater Toronto Area due to their numerous benefits, including privacy screening, low maintenance, attractive foliage, and environmental benefits. By following the proper watering and maintenance protocols, you can ensure that your White Cedar trees thrive and enhance the beauty of your landscape for many years to come.
