Thuja is not only a true eye-catcher as a hedge, it also makes a good cut in shape. Very popular among them are spirals, balls and cones.

Cut thuja into shape

Thuja does not necessarily have to be cut regularly. In order to stimulate the growth of the plants and to create an attractive eye-catcher, however, shaped cuts are indispensable. The cutting of hedges promotes uniform growth. The eyes are shortened by one third of the new wood.

Thujen can be very well in shape. The most popular forms include ball, cone and the pyramid.

Thujen cut - yes or no?

A cut is not a must, but promotes the growth and visual appearance of plants. If the plants grow dense and thereby form their natural growth habit, no extensive cutting measures must be carried out. An annual shape cut is perfectly adequate. The new shoots are cut to preserve the natural growth habit. This can be round, oval or pyramid-shaped.

" Tip: If young plants are not cut in the first two years, this has a positive effect on rooting.

In order to obtain a uniform hedge or to cut the thuja in shape, it should be used up to three times a year to scissors. This promotes a dense and compact growth.

Thuja cut - what is possible?

Thujas are very suitable for a shape cut and numerous decorative elements are possible. If Thujas are planted as a hedge, a trapezoidal shape is usually sought. The hedges thus appear slightly wider at the bottom and taper towards the top. This has the advantage that in winter not too much snow collects on the hedge and leads to a break of the branches. Furthermore, a lighter honeymoon is more translucent, which contributes to a compact growth of the plant.

The spherical or conical shape are classic shape cuts and very common in Thujas in gardens or parks. If you want to challenge yourself, try a pyramid or a spiral. Nobody has to rely on his own judgment. Stencils and patterns provide assistance.

When should the shape cut be made?

Mold cuts will be needed several times a year. Thuja can be cut between spring and late autumn. For hedges, a cut is usually sufficient annually. This is preferred when the new shoots are fully formed, about the beginning of July.

The following time periods are available for the shaping of ornamental elements:

  • Mid-April
  • end of June
  • end of August

Cutting measures should be avoided from September so that the new shoots can mature before the winter and no frost damage occurs.

The cut compatibility

Thujas usually do not resent a back or shape cut and are easy to cut. However, there are still some things to consider. At the interfaces, there is a leakage of liquid. Cutting at full sun can quickly result in browning of the leaves. Should always be cut in dry weather. If the leaves are wet, this can promote the development of diseases that are spread by waterborne spores.

The right tool for the shape cut

For hedge trimming, motorized hedge trimmers are generally used. The shape cutting requires precise work and is preferably carried out with manual tools. Beidhandscheren have proven to be useful here.

Other tools can be used:

  • Lopper
  • Pruning Saw
  • hedge clippers
  • Handcutter

Every cut means stress for your plants. To keep the cuts as small as possible, the blades should always be sharp. Dirty blades can cause germs to get into the cut. Therefore, it is advisable to thoroughly clean the garden tools after use.

Wire as a tool for the shape cut

In order to get the thuja in shape, wire has proved to be a useful tool. From crafting wire templates can be produced for the shape cut without much effort. This is particularly easy to achieve with the spherical or conical shape. Wire can also be used to fix individual branches, so that the desired figure can be worked out better.

Some forms have proven particularly useful in the Thuja shape cut.

The Thuja as a cone

The conic is easy to realize even for beginners. First, a rod is placed in the middle of the floor. Then a string is stretched, to which a piece of wood is fastened. This will now draw a circle on the ground. Within this radius strings are stretched. The template takes on the shape of an Advent wreath. Now cut along these boundaries.

" Tip: In the cone shape, the cut is made from the tip.

Thuja as a ball

Balls are very easy to cut. Stencils can be easily made from cardboard or wire by yourself. Wire templates can be completely put over the plant. Overlapping branches are simply trimmed. Cardboard stencils are moved around the plant. Outstanding branches are removed from the circle.

The Thuja as a spiral

This shape cut will be more elaborate. The best prerequisite for a successful spiral is the conical shape of the Thuja. So it makes sense, first, as written, to develop a cone and then work out the spiral shape. A template made of wire facilitates the work. Make a spiral and put it over the plant before you start cutting. The distances can be chosen arbitrarily. The conclusion can be designed as a top or ball. If the ball shape is desired, just make a separate template and make the ball at the end of the shape cut.

How to cut?

Old or dry branches are trimmed with the hedge trimmer. The cut is carried out on the healthy wood. You should remove any intersecting or overlapping branches as these may obstruct air circulation. On dead branches and twigs fungal diseases can arise. These branches are generous to cut. If gaps have been created by these necessary cutting measures, which affect the appearance of the plant, branches can be pulled into the space with the help of wire as a gap filler.

Thuja cut in diseases or pest infestation

Thujas can be attacked by some diseases and pests. These include:

  • mushrooms
  • spider mites
  • mildew
  • Thuja minimizing Motte

Affected plant parts are generously cut out. After the last frosts, the first cut can be made. Most affected plant parts already show brown discoloration. In summer, another cut should be made for safety.

" Danger: Cut off plant parts do not belong to the compost.

The different types of Thuja show different growth. The frequency of cuts will vary. The Thuja Brabant, for example, is particularly vigorous and will grow accordingly fast to the desired ball or pyramid. When cutting hedge, it should be noted that the compact hedges are often chosen by birds as a refuge. Check the hedge before cutting. Breeding birds, the hedge trimming is postponed until the breeding season is over.
