Thuja is a genus of coniferous trees and shrubs in the Cupressaceae family, native to North America and East Asia. They are evergreen plants that can grow from 3 to 60 m in height.
Most thuja species have a straight trunk covered with fibrous, reddish-brown bark. The shoots are flattened and grow in a single plane. The leaves are scale-like and range from 1 to 10 mm in length. They are ornamental trees, planted in gardens and parks. They can be found as solitary specimens or in groups, but most commonly as hedges.
In terms of light, thuja thrives best in direct sunlight but can also tolerate partial shade. It is also a frost-hardy species, and growth is optimal in loamy, calcareous soils that drain well. It does not tolerate compacted soil or excessive moisture, conditions that can lead to disease. Therefore, watering should be moderate and done only when the soil surface is dry.
Pruning: These trees are well-suited for pruning into various decorative shapes. Pruning to maintain shape is performed annually in May. Only the current year’s shoots should be pruned, not the older branches. It is very important to plant only plants with a root ball (soil around the roots), and planting can be done starting in the fall, after the first frost, until spring, when the soil is not frozen and there is no danger of frost.
Gently remove the plant from the pot or bag surrounding the root ball to avoid scattering too much soil. For propagation, thuja species can be propagated by seeds or cuttings as follows: seeds are harvested in the fall and sown in the spring, after which they are left in place for 2 years; or propagation by cuttings, which is done in the summer using semi-woody branch sections. This is a more difficult process, recommended for professionals. Diseases that can affect thuja include: necrosis of branches from the outside in, necrosis of branches from the inside out, and plant desiccation. Among the pests that can affect thuja, the most common is the thuja scale insect. Important: Due to the dense outer layer of the crown, the plant becomes sparse on the inside. This is a natural phenomenon and does not require treatment. These trees are well-suited for urban environments.
Disease control treatments can be carried out at any time of year, provided that there is no precipitation at the time of application (or in the following hours). Additionally, temperatures should not be too high, and, of course, depending on the time of year the treatment is performed, there should be no risk of frost. Sprinkler irrigation is NOT recommended.
