Tree of life as an evergreen garden hedge

Plant and cultivate the Tree of Life as an evergreen hedge: life

The tree of life, often called also Thuja, is planted in many gardens as hedge and offers as evergreen plant one Year-round visibility and noise protection.

At the right location, most Thuja varieties grow up to 40 cm a year, so you can quickly count on an opaque hedge.

In addition to a hedge plantation, the Thuja is also gladly set as a specimen plant and cut into an attractive shape.

Here, with its green scales, it forms a beautiful backdrop for colorful early and summer flowers.

In general, the tree of life is considered easy to maintain and is therefore suitable for almost every garden.

Especially important is a sufficient water supply: Especially in summer, the thuja tends to blotch or brown discoloration.

In the following, we explain what you need to look out for in order to promote and maintain plant health.

Thujen are next to the pine and spruce to the coniferous plants, but do not train themselves needles. The small green leaves are reminiscent of needles in shape, but are referred to by botanists as shed leaves.

Thujen grow as evergreen shrubs or trees. Botanists generally distinguish five species, which differentiate into many different varieties:

  1. Korean Tree of Life (Thuja koraiensis)
  2. Occidental Tree of Life (Thuja occidentalis)
  3. Giant Tree of Life (Thuja plicata)
  4. Japanese Tree of Life (Thuja standishii)
  5. Sichuan Tree of Life (Thuja sutchuenensis)

In addition to a different appearance and different growth conditions, the five species can also be differentiated based on their aroma. Rubbing the green scales between your fingers releases an aromatic scent reminiscent of pineapple, applesauce, lemon, cloves or almonds.

Attention: trees of life are poisonous. Therefore, do not use a Thujen hedge if there are often children in your garden who could swallow the plant parts.

Small-sized Thujen also serve as a decorative specimen plant in the flowerbed.

Particularly suitable For a garden planting are varieties of the datura tree of life, as it is also offered in numerous zwergwüchsigen new breeds and is thus ideally suited for planting as a hedge and specimen plant.

A popular strain is Thuja occidentalis emerald, their especially fine scales leaves stay green in the winter and do not turn brown even with heavy frosts.

Plants of this variety grow narrow to the top and therefore rarely need to be cut in shape at the bottom.

Extremely cut-tolerant is the variety Thuja occidentalis Brabant. In addition, it is considered a particularly dense and fast-growing tree species, making it well suited as an opaque garden hedge.

Opposite is the variety Thuja occidentalis Teddy. you grows very slowly, but also develops especially soft scales leaves.

If you do not hedge but one Solitätpflanze You can put on plants of the variety Thuja plicata Aurescens To fall back on. However, this vigorous thuja must be cut regularly in shape, otherwise it grows quickly high and wide and shadows other perennials and ornamentals.

By the way: Thujen are often confused with the cypress. The latter, however, is much wind- and cold-sensitive, but tolerates shadow better than the tree of life.

Site claims and planting of the tree of life

Plant and cultivate the Tree of Life as an evergreen hedge: plant

Thujajungpflanzen (here: Amber Glow) are offered as container goods. The age as well as the size of the plants vary.

The tree of life prefers a sunny location with one wet, slightly swampy soil.

If the substrate turns out to be too dry, the scale leaves of the Thujen turn brown unsightly or whole shoots die off.

Many dark hours have similar negative effects:

Too little sunlight causes a weak and much more transparent plant growth, so that the hedge does not develop sufficient privacy. In addition, the soil should be slightly acidic.

Tip: A Thujen hedge is often used for gardening. However, keep in mind that Thujen, like almost all coniferous trees, is extremely sensitive to high salt concentrations in the soil. If salt is scattered in the immediate vicinity of the stern during the winter, you should choose a different location or less susceptible hedge plants.

The tree of life develops as coniferous tree no needles, but so-called scales leaves.

If the ideal location is found, be in one Planting distance of about 40-50 cm dug the corresponding planting holes: The hole should be twice as large as the root ball and also deep.

Loosen the ground with a digger fork and remove possible sick or dead root parts. If the root ball is very dry, it is placed in a dipping bath before planting until no more air bubbles rise.

Before insertion in the planting hole, the roots are gently loosened with your fingers. Straighten the young plant straight and turn the most visually appealing side in viewing direction.

Now the excavation is treated with organic fertilizer, distributed around the root ball and lightly pressed - try to avoid air pockets and finally water everything well. An additional bark mulch layer prevents too fast water evaporation and thus optimizes the soil for thujen growth.

Tip: In young hedge plants, it is advisable to set additional support piles, which provide for increased stability and thus facilitate the rooting of the plant. After a few months you can remove the supports again.

To care for Thujen

Thujen are evergreen trees and remain opaque in winter.

The tree of life is generally considered particularly easy-care hedge plant, as it is already planted very well and for a long time with a low maintenance effort, planted in the right location.

As a water-loving plant is the tree of life one regular watering especially important: The root system of the hedge runs flat under the earth and must absorb a lot of moisture to keep the scale leaves green and handsome.

If there is a lack of water, the shoots turn brown and die.

Tip: Targeted mulching - covering the soil surface around the plant base with organic material - helps to maintain soil moisture and is recommended as a preventive measure for a Thujen hedge.

Since the tree of life is strongly sensitive to salt, may no mineral fertilizer come to the application. Prepare the planting substrate with horn shavings or humus and return to specialist nutrient supply for so-called conifer fertilizers.

Many Thujensorten are particularly cut compatible. Nevertheless, the pruning should never take place in the old wood, since Thujen permanently kahlten from the inside and here no new shoots form more - so perform the cut conical (in trapezoidal shape). Many varieties grow in height, so you rarely have to cut the hedge near the ground in shape.

Multiply tree of life

Thujen become multiplied by semi-woody cuttings. These are cut off in late summer and placed in high-quality potting soil. Important information on the right procedure can be found on our consultation page on cuttings propagation.

Propagation via seeds is possible, but very laborious and rarely successful. Self-sowing, on the other hand, can certainly take place at the optimum location.

Diseases and problems of the Thuja hedge

In the case of life trees, brownish discolorations and other damage are often observed, which may result in death of the shoots or the entire hedge.

The causes are different, but can be on two common problems of Thujen attributed to persistent dryness as well as strongly acidic soils have a negative impact on plant health, causing leaf and shoot diseases.

water shortage

Thujen are evergreen trees and remain opaque even in winter. The tree of life is often attacked by fungal diseases or root rot. The damage shows up in discolored scales.

The finely branched root system of the Thujen runs flat under the ground and reacts extremely sensitive to lack of water, also occur after the Pruning in June Rapid burns on the leaves if the plant is supplied with too little water.

It is therefore important to strengthen the trees throughout the year, but increasingly in the summer, through a regular water and nutrient supply optimally.

But not only in the warm season, even in the cold months there is a risk during long periods of frost that the hedge dries up.

Because evergreen trees evaporate water over their fine leaves even in winter: If no water is replenished from the frozen soil, dry damages occur. Water your Thujenhecke therefore also in the winter regularly on frost-free days.

Road salt damage

Conifers are sensitive to high salt concentrations in the soil. These can be caused by the winter salt distributed or a regular mineral fertilizer. A typical symptom is brownish shoot tips near the ground.

To avoid salt damage due to too high salt concentration in the soil water, you should therefore resort to special conifer fertilizer or organic fertilizer and not plant your hedge directly next to the walkway.

Use a hedge trimmer to remove brown spots and water the soil vigorously so that the salt is rinsed into deeper layers of soil that the root rhizome can not reach.

root rot

Thujen is particularly prone to developing root diseases caused by different fungal spores, such as the mushroom Phytophthora cinnamomiwhich destroys the bark tissue of the roots, whereupon the shoots turn yellow and finally brown, before they die altogether.

Particularly vulnerable are trees of life, which are weakened due to strongly condensed soils - optimal soil preparation is therefore the best preventive measure.

Is a plant infected? It must be removed immediately together with root ball and disposed of in the residual waste or burned, as the fungus can quickly transfer to neighboring hedges and other garden plants.

If the fungus is recognized in time, Special fungicide solutions can be applied in the casting process. However, effective treatment and long-term plant health can not be guaranteed even as the fungus outlives many months in the soil.
