When it comes to conifers, many gardeners are really excited. Because these are not only easy to use and maintain, they also offer numerous advantages. In this way they offer good privacy protection, which is created very quickly because the conifers grow quickly. At the same time, conifers can be shaped to a certain shape, i.e. thinned out at will, so that they get a nice growth. If you are looking for something special, you will often find the Japanese Sickle Fir (Cryptomeria Japonica), which originally comes from China and Japan. After all, it is not a very common, but noble and respectable alternative to the typical coniferous tree in Europe - and also convinces with a very nice wood that brings a slight red cast.

Why propagate Japanese sickle fir?

Japanese-style sickle firs prefer to be a little more protected and grouped. At the same time, when properly shaped, they provide ultimate privacy, can act as a kind of hedge and provide plenty of shade on hot days. So if you have enough space and enjoy the look of the Japanese conifer, you can propagate and plant it as you wish. However, there is another reason that speaks for the beautiful fir: Its wood is very popular as construction timber and is also often bought because of its reddish color. An equally positive feature of the Japanese Sickle Fir is that it grows very quickly - if gaps in the garden have to be closed or if an old tree has died and been removed, the Japanese Sickle Fir provides an appealing remedy. The big plus of the tree: It can also be used as a bonsai and looks particularly beautiful in miniature form. The fact that the propagation of the Japanese conifer is very easy also speaks for trying out the process yourself - even if the offshoots should only be given away as a gift.

Propagate with cuttings

If you want to grow a second Japanese sickle, we recommend the route via cuttings. Faster and more successful results are to be expected than with sowing. In this way, bonsai can also be created that gradually grow to perfection in miniature size with a little patience and care.

Win cuttings

It is best to separate the cuttings from the tree at the end of autumn, with a size of 15 to 20 cm being ideal. When cutting, make sure that the pruning shears that are as sharp as possible are used to keep the cut as smooth and small as possible - at the same time, the cut should be held at an angle so that water can drain off when it rains and the rest of the shoot does not rot.

Prepare and plant cuttings

The cut cuttings must now be freed from the pine needles on their lower part. However, one should proceed carefully so that the bark is not damaged and no cuts are found that could prevent germination and damage to the shoot from growing. Now you need a sufficiently large flowerpot that needs to be filled with humus-rich, but nutrient-poor soil. The cuttings are inserted into this - about so deep that they are half covered. A cling film over the flower pot helps to accelerate and promote the rooting of the shoot.

Maintain cuttings

The flowerpot with the cuttings or several cuttings should at best be placed in a frost-protected place with lots of light - this way they can overwinter and root. For this, however, they need a regular water supply, because the earth must always be kept moist. To prevent mold from forming or the cuttings from starting to rot, the cling film should be aired at least every two days and replaced if necessary to minimize germs. If the offshoots have already taken root, they should (if not already done from the beginning) be separated from each other and put in their own flower pots - otherwise their roots become entangled, so that they can hardly be separated later without damaging the roots.

Propagate through sowing

You can also multiply the Japanese sickle fir by sowing seeds. If you already have a copy at home, you can get it from the pine cones. You can also use purchased seeds.

You should be aware that it takes a long time to propagate through sowing and that it takes a lot of patience and time to take care of the seedlings. It can take years until a somewhat robust young tree has developed that can be placed in the garden and successfully overwinter there.

When propagating by sowing, you can work with a cold frame and cling film to speed up the sprouting of the seedlings. A slightly sunny, medium-warm place is ideal for this. Make sure that the soil of the seedlings - at best humus-rich and somewhat enriched with nutrients - is always kept moist. Waterlogging should be avoided, as well as mold formation due to insufficient ventilation. In this way too, the cling film should often be ventilated and replaced. If the seedlings are large enough, they can move to a large flower pot. As already mentioned, however, it takes years for the small, tender plants to become young trees that really stand up to European weather in the garden.


It doesn't hurt to internalize all the key points again before you actually start to multiply the Japanese sickle fir - otherwise you will forget the one or other important point that could ensure the success of the action. Here is a brief overview of all the procedures:

Propagation by cuttings

" When growing over cuttings, cut shoots from the tree that are at least 15 to 20 cm long - be careful of oblique cuts
" Remove the needles from the lower part of the cuttings - avoid damaging the bark
" Place the cutting in nutrient-poor soil and keep it moist
" at best cover with cling film that needs to be ventilated
" bright, frost-protected place to spend the winter
" if there is sufficient rooting, transfer it to individual pots

Propagation by seeds

" if there is propagation by seeds, offer a cold frame with soil and nutrients
" Always keep seeds and seedlings moist, but prevent waterlogging
" Separate seedlings later and repot individually
" Only plant out after a few years with sufficient strength

Whether growth is successful or not depends on many factors. However, if you absolutely want to be successful and don't have as much patience, you should select propagation via cuttings. Because this process mostly succeeds and does not take that long.
