The Thuja emerald is cut compatible, you can still do a lot wrong

How to cut Thuja emerald exemplary - editing tutorial about the noble Thuja variety

As a solitaire and hedge, Thuja Emerald fades other conifers with intense colors. Whoever does not simply leave the premium variety under the trees of life, will be rewarded with a long-lived and shapely conifer in the emerald-green needle dress. This tutorial answers all questions about the cut care of Thuja occidentalis emerald.

Tricky cut

If you have prescribed a pruning for your Thuja emerald, the incision requires special attention. For conifers in general and trees in particular, pruning can have fatal consequences unless specific growth is taken into account. Characteristic of Thuja occidentalis and other conifers is that they no longer expel from old wood.

The cause of the handicap is the lack of sleeping eyes as an "iron reserve of growth" when branches, branches or trunks fail. Most deciduous trees produce a variety of dormant buds, which guarantee re-growth after pruning. Thuja emerald is forever disfigured when you cut the shrub into old wood. As long as the cut on the green needled branch area concentrated, proves a tree of life as well cut compatible.


Occasions and dates for the cut - types of cuts

Leisurely growth of 10 to 20 centimeters per year does not prevent Thuja Emerald from reaching a majestic height of 6 meters uncut over the years and a generous width of up to 2 meters. These dimensions create considerable space problems in the small garden. The concerns expressed against a radical cut recommend the regular grip on pruning shears. In order to keep growth under control without affecting the emerald green colourfulness, the rule of thumb is: better frequent and moderate rather than rare and vigorous cutting. The following table familiarizes Thuja-Gärtner with all options around expert cutting care:

A radical rejuvenation cut can be deleted from the list of useful cuts without replacement. Thuja emerald should never be cut into old wood. This premise implies that you use the conifers as a shrub or hedge do not put on the stick without being able to challenge the total failure.


Build a solitary staircase

Characteristic of Thuja emerald is a tight upright and slender growth. High-quality young plants leave the nursery with several scaffold shoots. These compete with each other and usually drive on the exposed side to win the race to the light. The result is a one-sided weight distribution, so that the tree of life falls apart under the influence of snow pressure or strong wind. A targeted construction cut prevents the unwanted process and strengthens the stability within the conifer. How to do it right:

Examine a solitary Thuja emerald in every late winter of a close examination. The cut care runs in the perfect frame when three side uncut branches meet at different heights. This succeeds through a derivation cut. To shorten a too long side shoot, look in the upper third of the needled area a strong side branch. Where both shoots fork, start the cut.

Premature caps of the main drives mark the end in altitude growth

A Thuja emerald continues to grow slowly but steadily as long as the buds are crowned with lace buds. This applies equally to the cut care of solitaire and hedge. Please pin shoot tips only if no further growth in height is desired. The Peak Growth Act teaches us that after removal of tip buds, growth forces are distributed to deeper buds. As a result, a Thuja emerald will always stick out when it is deprived of its uppermost bud.

Construction cut guarantees opaque hedge

Thuja Emerald takes time to grow. With a growth rate of 10 to 30 centimeters, it takes many years of patience, until the trees of life form a view-tight hedge. Understandably, every green centimeter is noted with joy, so gardeners do not prune their thuja hedge in the early years. As a result, a loose habit develops that is highly susceptible to windthrow and snow pressure. For this reason, this tutorial argues for a successive construction section that aims at a densely branched and lushly needled Thuja emerald hedge. This is how it works:

The gradual upbringing of a Thuja emerald hedge takes special account of all the lace buds, as long as the desired final height is not reached. Blend all sides and flanks up to 5 centimeters. At the base, the hedge should be wider than in the crown area for a light-flooded growth. Annually pruning the lateral shoot tips in the needy area promotes a dense branching, because even further down the shoot buds profit from the sap flow.

A sectional profile in trapezoidal shape is equally advantageous for solitaire and hedge. If Thuja emerald grows below one-fifth to one-third wider than in the crown, its shoots will not shade each other. This promotes photosynthesis and allows green needle shells to sprout deep inside the plant.

Cut thuja emerald hedge into shape

If a Thuja emerald hedge has reached the perfect height and density, the structure merges into one annual shape cut, The editing is considerably simplified, because you can orientate yourself to the clearly recognizable interfaces of the previous year. There is no longer a danger of accidentally cutting too deep into old wood. This also eliminates the installation of orientation aids for the recommended trapezoidal shape. How to complete the central shape section with gardening expertise:

In contrast to the built-up section, a shape cut leaves only a few millimeters of fresh, green needle shed. For a straight cut surface, work on the hedge sides with stretched arms and out of the shoulders. The honeysuckle cut is done perfectly with pivoting movements out of your back.

Adequate tool for every type of cutting


If the right cutting tool is available, the cut by Thuja Emerald is a horticultural pleasure. To cut a hedge into shape, an electric hedge trimmer does the cutting work accurately and whisper-quiet. From a hedge length of more than 10 meters you will ideally manage the cut with a gasoline-powered hedge trimmer. For the independence of battery or power cable, the machine noise is exceptionally accepted in order to cut the mighty green wall. For the shape cut on the solitaire, the hedge trimmer can remain in the shed. Since the cut concentrates on individual branches, a high-quality one-handed pruning shears is dedicated to the task with flying colors. It is your opinion as to whether you prefer a bypass or anvil shears.

Summer cut for a well-kept hedge

Under ideal conditions, a Thuja emerald hedge grows up to 30 centimeters a year. This affects the well-groomed appearance, because nasewise shoots protrude from the hedge form. For a regulating care cut is the ideal time window end of June open. In time proximity to the Johannistag, the 24th of June, Lebenspäume and other plants insert a short break in growth and drive afterwards again with diminished strength.

If you blend a third of this year's growth in the summer, your Thuja emerald hedge will thrive even more densely and bushier. Alternatively, just cut branches that protrude from the shape. It is important to note that you cut at the latest until the beginning of September, so that fresh shoots in time before the winter matures.

Brooding birds always have priority

In the Federal nature protection law is a strict Grace period prescribed for the pruning. Basically it is from March 1st to September 30th prohibited to prune hedges, shrubs or treetops. Over the defined period, the breeding season of domestic and imported birds extends. Any disruption or even expulsion will be punished with fines of up to € 50,000. In exceptional cases, light nursing care may be allowed, provided that it concentrates on this year's growth. Furthermore, make sure before cutting back no nests in the woods are located.

Carefully inspect Thuja emerald for feathered inhabitants before each cut. If you find what you are looking for, please move the editing time to later. A pruning at the end of the breeding season between the middle of the year and the end of August is easily handled by a tree of life.

Tips

When choosing a timed cut for Thuja Smaragd, follow this rule of thumb: never cut in frost, high heat or blazing sun.

Solitaire benefits from the Auslichtungsschnitt

If a Thuja emerald, as a solitaire, has a professional construction cut, the cut care is reduced to an occasional clearing of deadwood. As illustrated below, on this occasion, you can cut back long or low-hanging shoots. How to do it right:

If you are forced to clear a dead or unfavorable branch, there is a danger of a large, dark gap. In this case, do not cut until you have bent the affected shoot by trial and error. If there is too much hole, move the point of intersection further outwards.


Too tall Thuja emerald with neglected drooping shoots brings a combination of Auslichtungs- and form cut back into balance. Light out dead branches. Cut long, overhanging branches through a derivation cut.

Derivative cut prevents brown gaps

The cut technique of derivation helps the private and professional gardener on some hurdle in the cut care. Designed for the perfect fruit woodcut on fruit trees, a derivation cut also guarantees ornamental shrubs, such as Thuja emerald, for optimum cutting results. Do not just cut a branch that is too long somewhere. Instead, choose the intersection at the fork to a young, fresh runner. The hitherto subordinate branch will take over a leading position at this point, without creating a disturbing gap in the appearance. You can also use the derivative to shorten a too tall tree of life.

frequently asked Questions

Accidentally cut into old wood so that my Thuja emerald now has a gap - what to do?

One moment did not pay attention and already the scissors got into the unadorned shoot area. So that at this point no permanent gap affects your Thuja emerald, proceed as follows: Pull neighboring, green branches of the branch into the gap and tie them there. For binding, please use soft hose binders that do not cut into the bark. It may take some time for the resulting gap to grow over and the binding material to be removed.

Is Thuja emerald suitable for keeping in a bucket? If so, how big should the pot be?

Lebensbäume have nothing to object to the cultivation in the bucket. As long as sufficient water and nutrients are provided for, the conifers thrive just as beautifully as in the bed. So that a Thuja emerald in the bucket does not tip over, the vessel should always be wider than the plant. At the beginning we recommend a pot volume of 25 to 30 liters. In parallel with the growth, the bucket has to be regularly enlarged so that the dimensions are correct.

We would like to plant an easy-care, evergreen conifers hedge that is only 200 to 250 centimeters high and 50 centimeters wide. With easy-care, we combine a small effort for pruning. Is Thuja Emerald a suitable strain for this plan?

Thuja emerald grows the slowest amongst the most popular tree species. Furthermore, the conifers generally remain lower and slimmer than varieties such as Columna or Malonyana. Of course, with age, Thuja Emerald will clearly exceed the desired height and width. By pruning the hedge once a year early, keep the growth shape compact and narrow. Regular cutting is better than cutting the bushes once to 250 centimeters when they have grown too big. In this case, a marked increase in thickness begins in the lower region, which requires an even greater shape cut.

In a development area, I plan the planting of Thuja emerald as a fence hedge. The soil is problematic because it is a former field, which was filled 170 cm deep with sand and gravel, so that hardly humus-like components are present. How deep is the Tree of Life root and how do I have to plant the planting trench?

The thuja hedge will not grow in a sandy-gravelly soil. The root depth of Thuja Emerald depends significantly on the local conditions, so that a concrete measurement is not to be made. Experience has taught us that in normal garden soil after 10 years, a root depth of 50 to 75 centimeters is reached. Therefore we recommend to dig a 1 meter wide and deep trench for the Thuja hedge, which you fill with topsoil.

I am forced to severely cut back a 25 year old Thuja emerald hedge deep into the old wood. The vertical main drives still have residual green at the tips. Can I stimulate growth here by cutting the branches and inserting a young green branch into the slot, similar to refining fruit trees?

With almost certain probability, scoring is as unsuccessful as refining. Conifers have set their growth forever in the old wood. This also applies to Thuja emerald. The hedge drives after a strong pruning only again if it is limited to the green area.

The 3 most common cut defects

If the emerald-green needle dress is marred by brown spots or the Thuja emerald hedge is shed, the gardener has made a classic cut. To keep the readers of this tutorial from making mistakes in editing, the following table lists the three most common mistakes with tips for effective prophylaxis:

Tips

When Thuja emerald shrubs use the land as a hedge, the glossy green shoots near the ground sometimes turn brown in winter. The cause is road salt, which is still used in many communities to keep icy roads passable. Prevent slide foil as a protective barrier in front of your Thuja emerald hedge. Clear the trees on mild days to remove saline spray. In February, cut off browned shoot tips with a hedge trimmer.
