Thuja hedge plants

Thuja-Hecke kaufen

A Thuja is the ideal plant for a plot boundary or bed border with its opaque, evergreen foliage, its frost hardiness and good tolerance to pruning. If you buy a Thuja hedge plant, you will get an attractive privacy screen and also wind protection, which blends in harmoniously into any garden due to its bright green shades. The Tree of Life, as Thuja is also called, also scores with its rapid growth and low maintenance. With regular pruning, a Thuja hedge can easily be maintained at any desired height. And here is another plus: although a Thuja is a conifer, it has soft, flaky leaves that smell aromatic when touched.

Convince yourself of the attractiveness of the Tree of Life! Whether high or low growing: in the Lubera® shop you will find the right Thuja for every garden design.

Buying a Thuja Hedge Plant – Shape and Structure for the Garden

With a Tree of Life, you can give shape to a hedge – a trapezoidal shape is very good with a Thuja hedge. But even compact, low hedges for bed enclosures can be easily grown with Thuja.

And if you do not want a shaped cut: the natural habit of Thuja – whether conical or spherical – comes into its own in a loosely structured hedge.

• The variety Thuja occidentalis 'Brabant' is a hedge classic. It can easily reach a height of four metres and grows up to 50 centimetres per year. With the variety 'Brabant' you can very quickly achieve an opaque hedge. It is also one of the most robust hedgerow conifers.

• Thuja occidentalis 'Emerald' convinces with its distinctive colour and its filigree, conical growth. With its annual growth of 20 to 30 centimetres, it needs a little more time than 'Brabant', but will reach three metres in height. Due to its growth form, 'Emerald' can be used to create very loose hedges. This variety should not be planted too close together.

• Thuja occidentalis 'Mecki' is an excellent boxwood alternative. With the small variety 'Mecki' you can make beautiful, low hedges in an ornamental garden.

Special Features of the Tree Of Life

Thuja is a valued hedge plant. It belongs to the conifers, although it does not have needles, but has leaves. These are leaves that fit closely to the shoot.

When a Thuja hedge has a rusty brown colour in the cold season, it is often the normal winter colour of the wood. In their native home, in North America, the plants adapt to the cold and dry winters. This colouration is observed especially in the wild species of the Western Tree of Life (Thuja occidentalis) and the giant Tree of Life (Thuja plicata). The variety 'Brabant' discolours only slightly; the variety 'Emerald' retains its beautiful colour even in the winter.

But even with long periods of drought and too much road salt, a Thuja can turn brown! Typically, the branch tips turn brown in the lower area towards the ground.

A Suitable Location

If you want to grow a Thuja hedge, you should not plant it under large trees if possible. Due to the high water requirement of the trees, it can happen that the Thuja hedge has to compete too much for water. In addition, Thujas, like most conifers, are sensitive to too much salt in the soil. Along roads that get plenty of road salt in the winter, you should be careful not to plant a Thuja hedge.

The location should be sunny to partially shaded. Shady corners are not suitable for Thujas. The soil should be permeable to water and provide sufficient nutrients to the plants. Thujas thrive in a slightly acidic, neutral or moderately alkaline soil. The optimum pH values ​​are between 6 and 7.5. Brown-black needle colouring may occur when the soil is too acidic. In this case, you should provide the soil with calcium carbonate and mature compost before planting (if possible, measure the pH first!).

Planting a Thuja Hedge Plant

If you buy a Thuja hedge plant, you can plant it in the spring or late summer. The spring is more suitable because the plants can establish themselves better. Trees that are not well-rooted show dehydration symptoms quickly in the winter. If you want to plant many Trees of Life, you should dig out a planting trench and, if necessary, work with a planting line for straight alignment. If necessary, add compost to the soil right at the beginning of planting in order to obtain a good supply of nutrients. If you are planting on a hillside, you should also create a sufficient watering edge if possible – otherwise there will not be enough water in the area of the plants.

For a Thuja hedge, the following planting distance (for 60 - 80 centimetres high shrubs) is a rule of thumb:

• Thuja 'Brabant': about 50 centimetres

• Thuja 'Emerald': about 40 centimetres

However, the ideal planting distance also depends on the desired hedgerow shape: hedges with a compact density are, in principle, planted a little closer together. By contrast, thin hedges naturally have larger planting distances. For example, the beautiful conical shape of a Thuja within a hedgerow formation, the distance can be generously sized. The Thuja 'Emerald' can reach a width of 1 to 2 metres as a solitary plant. 'Emerald' should not be planted too narrow; otherwise the vitality of the individual plants could suffer.

If you buy a Thuja hedge, you should also observe the distance to the neighbour during planting – the distances are regulated by law. As a rule, the limit distance is about one metre.

Thuja Care

In the first three years, you should ensure that your trees have enough water. Later, the plants have a well-developed root system, which helps them obtain moisture from deeper soil layers. But even in very dry winters with lots of winter sun you should water a Thuja hedge if necessary because Thujas are evergreen. With a mulch layer from leaves, grass clippings or bark, you can ensure that the moisture in the soil is kept longer. In the spring, a compost fertilisation is recommended. The added humus has a positive effect on the soil structure and the water storage capacity of the soil.

If the soil tends to be acidic, you can use calcium cyanamide (nitrolime), which also provides your hedge with magnesium and calcium.

The Right Fertiliser

Special conifer fertilisers not only contain nitrogen but also other suitable nutrients for trees, however less potassium and phosphorus. Magnesium and iron provide the rich leaf colours of Thujas. Especially in sandy soils, which cannot keep nutrients well, the use of special fertilisers makes sense.

Since a Thuja is sensitive to salt, you should be careful with Blaukorn® fertiliser because this mineral fertiliser increases the salt concentration in the soil water.

Compost, horn shavings or horn meal are good fertilisers for a Thuja hedge. They can be applied from the spring until the summer. Fertilising with compost in the spring and magnesium in autumn is usually sufficient for a good clay soil.

Epsom salt provides magnesium as magnesium sulphate and gives the Thuja leaves an intense colour. If the Thuja leaves lose their original colour, Epsom salt can help as an immediate measure.

Pruning a Thuja Hedge

If you buy a Thuja hedge, you can prune right after planting. This is how you can reduce high water evaporation in the early days. Thujas are quite thirsty as young plants.

Thuja hedges should be pruned regularly if they are to grow dense and visually beautiful. But be careful: avoid a strong cut into the old wood; otherwise there is a danger of holes that will no longer grow.

Two cuts per year are recommended for high-growing hedges: the first cut should take place at the end of June and second cut at the end of August. A trapezoidal shape has advantages: if you cut your Thuja hedge wider at the bottom than at the top, more light arrives at the lower areas. Even a high snow load becomes less of a problem.

Buying a Thuja Hedge – Note: It Is Slightly Toxic!

A Thuja can cause skin irritation if touched. So always wear gloves when pruning. When consumed, the toxins of the plant cause vomiting, diarrhoea and/or kidney damage. Do not leave your hedge trimming on a pasture; otherwise there is a risk of poisoning livestock.
