The botanical thuja is also called the tree of life and can be seen in many domestic gardens. It is one of the most popular hedge plants because the thuja is a very robust plant. It keeps its color all year round and is available in numerous varieties. If you want to multiply the botanical thuja, it is best to do this with cuttings. The propagation of your own plants has the advantage that they are guaranteed to be varietal. In addition, the hedges grow better if you use your own cuttings instead of the usual sowing.

The right time

Basically, the botanical thuja can be propagated all year round. However, the best time is midsummer. At the end of June, the shoots of the plant are large enough and woody enough to become a large hedge. However, the cuttings need a cool place with high humidity. A small greenhouse is best suited for this. Since you usually don't have this at hand, you can alternatively use a transparent plastic bag. The increase in midsummer has the advantage that roots form faster and the plant can grow quickly.

Multiply thuja: you need that

To multiply the thuja, it is best to use the branches of mother plants. These should be vigorous and not too old. Larger branches are cut out of the mother plant. Hidden areas should be preferred so that there are no large holes in the mother plant. The branches are not the main material of the propagation, but the small risslings are used. Risslinge are thin side branches. These are torn off at the junction. The purpose of tearing it off is that roots form more easily.

These working materials are required

Only a few materials are required to multiply the botanical thuja. A good pair of secateurs should be available so that the branches can be cut straight from the mother plant. Sufficient plant pots must also be available to use the risslings. In addition to the appropriate growing soil, only a plastic bag and a cord, or a greenhouse are important to create the necessary humidity.

Here is the list of all materials:
✓ good secateurs
✓ Plant pots
✓ Cultivation soil
✓ Plastic bag with string or greenhouse

Multiply thuja - step by step

Step ❶ - prepare cracklings

If you have cut off all the branches, you must first prepare the risslings. The side shoots are torn off the branch from top to bottom, so that there is still some bark from the branch on the tears. If the bark is too long, you can cut it off with secateurs. There should still be about half a centimeter of bark at the bottom of the crack. At the lower end of the tear, all side shoots are now carefully cut off. The foliage should be cut in half. If you have done everything correctly, you should now hold a cutting about eight centimeters long in your hands.

Step ❷ - Prepare planters

You have two options here. You can use a larger container to insert all of the cuttings, or you can use small planters that each hold one cutting. The planter is filled with standard growing soil. The earth should be pressed a little. This works best if you moisten the earth a little. Now use a wooden skewer to pierce small holes in the ground into which the crackling will be placed later. The holes have the advantage that the ends of the crackling do not bend when you push it into the ground.

Step ❸ - insert rips

The prepared cracklings are carefully pressed into the ground. The crackling should be placed about two to three centimeters deep in the ground. Make sure that the cracklings are securely in the ground - vertically upwards. If you use a large planter, it is essential to allow enough space between the cracks. This is the only way the roots can form and develop accordingly. About ten centimeters between the cracks is ideal. If all the cracklings are inserted, they are cast on well.

Step ❹ - The right cover

The risslings are now covered with the lid greenhouse covered. Alternatively, you can use a plastic bag that you put over the small seedlings. The bag can be tied to the planter with a string. It should be ensured that there is enough oxygen in the bag. The little risslings should now look like they are in a balloon.

Step ❺ - care of the rips

ATTENTION:
The botanical thuja is very toxic, which is why the risslings should not get into the hands of children. In addition, the rearing should be stored in a place where pets have no access.

The cracklings need a very high humidity. This is guaranteed with the cover. The cracklings should be placed in a medium warm place, without direct sunlight. It is important that they are in a bright place. Water the cracklings every three days. At this point, the cover can be removed for a few minutes. This way the plants are aerated and get fresh oxygen. Soil moisture should also be checked regularly. Always keep the earth moist and warm. So the roots can spread quickly and grow well. The thuja grows relatively quickly. After a few weeks you can already see how the cracks have grown. The risslings are allowed to grow in the planters over the winter and are set out next spring. It will take a few years for a large hedge to form.

The botanical thuja is a hedge plant that grows very quickly. It is ideal as a border for the garden because it provides optimal privacy.
