Planting and Maintenance

Planting Process

When planting arborvitae trees, it’s essential to choose the right location. They thrive in cooler climates and prefer a spot with full or partial sunlight. The soil should be moist but well-drained, with a pH level that is slightly acidic. Before planting, prepare the soil by tilling and mixing in compost to improve drainage and provide nutrients. Dig a hole twice the width of the root ball, ensuring there is proper drainage to prevent root rot.

Place the arborvitae tree into the hole, making sure it’s at the same depth as it was in the container or burlap wrap. Fill the hole with soil, and gently tamp it down to remove air pockets. Water the tree thoroughly and apply a layer of mulch to help retain moisture and regulate soil temperature.

Care and Maintenance

Arborvitae trees are generally easy-care, but they require proper maintenance to ensure their health and longevity. Watering should be done consistently, especially during the first few years, to help establish a strong root system. In drought-prone areas, it’s essential to provide supplemental irrigation.

Fertilize the trees every spring using a balanced fertilizer, and prune them to maintain their desired shape and size. Pruning should be done in late winter or early spring to avoid damaging new growth. Although arborvitae can tolerate partial shade, they perform best in full sun, ensuring their foliage remains dense and vibrant.

Pests and Diseases

Arborvitae trees are vulnerable to several pests and diseases. Bagworms, spider mites, and deer are common threats that may cause damage to the foliage and branches. To manage these pests, it’s essential to monitor the tree’s health and take preventive measures like using insecticidal soap for mites and installing deer fencing.

Various diseases, such as root rot, can affect arborvitae trees, particularly in poorly-drained soils or with improper watering practices. By ensuring proper planting and care techniques, the risk of disease can be minimized.

Varieties and Growth

Several arborvitae varieties, also known as Thuja plicata, are suitable for different landscaping needs. The Green Giant variety is a popular choice due to its fast-growing nature and resistance to pests and diseases. At maturity, it can reach impressive heights, making it ideal for privacy hedges or tall screens.

Other cultivars include the rounded “Hetz Midget” with its slow growth rate and dwarf size, suitable for small gardens and borders. The pyramidal arborvitae tree can grow quite tall and features a strong and upright structure, making it an excellent option for adding vertical interest to a landscape.

In summary, planting and maintaining arborvitae trees requires proper care, but their versatility and resilience make them a valuable addition to any landscape. By choosing the right variety and cultivating healthy trees, we can enjoy arborvitae’s unique aesthetic for years to come.
