The Thuja occidentalis emerald belongs to the tree of life and the cypress family. The evergreen, hardy plants are mainly used as a hedge plant because they grow quickly and form opaque hedges. The thuja hedge is also good wind and sound insulation. Emerald buoys generally grow slender, upright and conical.

Around the trunk are numerous thin, flexible branches with smooth, slightly shiny needles, which result in a filigree leaf shape. The leaves are light green in young specimens and fresh shoots, later the color darkens slightly, but always remains strong green in healthy plants. In autumn the thuja also wears small cones. The leaf color of the emerald hatch is completely preserved even in winter.

Important:
Always be careful. Leaves, branches and stem contain thujone, an essential oil. This creates an aromatic fragrance, but be careful, the parts of the plant are poisonous. Touching can irritate the skin. The leaves should never be eaten.

Growth and growth behavior

Emerald buoys grow approximately 20 to 30 centimeters per year. The growth mostly goes up until they reach a total height of between 2 and 5 meters. The width of the thuja extends only slightly. Full-grown plants become about 1 to 2 meters wide if they are free-standing and not pruned.

Location and soil conditions

The Thuja occidentalis emerald does not place any special demands on the location. It thrives practically everywhere. The soil should be moist, humic and nutritious.

A distance of 20 to 40 centimeters between the individual plants is ideal for planting as a hedge. But it is also easily used as a solitary plant in the garden. It can also be kept in a bucket, although the thuja clearly grows better and denser outdoors. Here are some more tips on how to properly plant a thuja.

Care and prevention of diseases and pests

Cut:

The plant is easy to care for and robust. A particular advantage of emerald thuja: it can be cut into shape at any time. The cut to limit the height is often sufficient after it grows narrow anyway. Only the branches that are very annoying are cut back on the sides. In general, however, the thuja itself forms a beautiful, cone-like shape that tapers to the top.

Watering and fertilizing:

Despite being related to the cypress, the thuja is not insensitive to long hot and dry periods - so water regularly in summer.

Single plants need less fertilizer than hedge plants, but it is not entirely possible with both plant forms. Fertilization in the spring with compost, stable manure or a long-term coniferous fertilizer is ideal. If the important nutrients are missing, the tips of the leaves turn brown.

Diseases and pests:

Diseases and pest infestation are rare in healthy Thujen. The main cause is too moist soil, which can promote stem and root rot as well as fungal attack. A soil that is too dry, on the other hand, attracts pests such as beetles, caterpillars and spider mites.
