While the golden larch (Pseudolarix amabilis) is difficult to reproduce in its natural size, even in botanical gardens, bonsai growers can achieve quite good results. If you already have a mini tree, you can ensure through direct propagation that the young plant brings the properties of the mother plant. For example, this is not always the case with propagation by sowing.
You can now read about what needs to be taken into account when reproducing the gold larch as a bonsai and how to proceed step by step.
Two ways of propagation
The gold larch can be propagated using the following methods:
Cuttings propagation - uncomplicated and simple
The Japanese call the propagation of cuttings "Sashiki". The propagation of cuttings is particularly popular in bonsai breeding. If you already own a plant, you can grow new plants inexpensively and easily.
Tip: Compared to growing from seeds, a cutting has a growth advantage of up to one year.
The cutting is easily cut from the gold larches. A length of five to ten centimeters should be observed. The cuttings can be up to half a centimeter in circumference.
Tip: Larger cuttings reduce the chance of successful rooting.
The right time for the propagation of cuttings
Since the gold larch is not a larch in the actual sense, but is a conifer, the propagation of cuttings can begin at two different times. Cuttings can be cut between July and August, and in autumn and winter, between October and January.
A special feature of conifer propagation is the tearing of the cuttings. The shoots, which are already well wooded at the base, are torn from the branch. It is intended that the bark will crack. This gives the cuttings more hold in the planter.
Tip: Limit yourself to woody cuttings. If too much plant sap flows through the branches, they will hardly form roots.

7. Wait for root formation
First, choose a planter. A bonsai pot is just as suitable for this as a conventional flower pot. However, there must be sufficient drainage holes for the irrigation water in the bottom of the vessel.
So that there is no waterlogging and the cuttings die, there is a drainage layer on the bottom of the vessel. To do this, add gravel, shards of clay or other coarse material to the bottom of the pot. The drainage layer is covered with conventional bonsai soil.
Tip: The substrate should be rather low in nutrients. This encourages the cutting to take root.
Put the cutting in the ground and press it lightly. Always keep the substrate slightly damp. However, make sure that the cutting does not get too much moisture.
You should set up the planter warm and bright. Soil heat is particularly important, i.e. a location near the heating system or by the warm south window. If a plastic cover is placed over the planter, a greenhouse effect is created, which stimulates root formation. The cutting should reach about one centimeter into the ground.
You will have to wait a few months until the first roots form and the cuttings sprout.
What happens to the young plants?
It will take a few years before a bonsai can be raised. The gold larch is cultivated as usual and transplanted every two years. Transplanting is used as an occasion to prune the roots. These are cut by around a third. The taproot is completely removed. Then the later bonsai gets a secure hold in the flat planter. When the tree has reached the desired shape and size, it is transferred to the bonsai pot and regular shape cuts are made so that the small gold larch retains its shape.
Multiplication by grafting
Grafting, referred to by the Japanese as "Tsugiki", is also widespread among bonsai fans, but should be in the hands of experienced gardeners. Grafting is about growing a base consisting of roots and a trunk with the rice, the upper trunk area with the branches located there. This technique is also known from orchards to grow two plants in an interesting cross.
Bonsai growing involves grafting to complement branches, add roots or grow a new tree.
When should be grafted?
For most deciduous plants, spring and summer are the ideal times for this technique. Since the gold larch is actually a species of pine, the winter months should be preferred for grafting.
Grafting larch - step by step
❶ Select rice
❷ Cut underlay
❸ Cut rice
❹ Paste rice
❺ Connect rice and pad
First the rice is selected. In this specific case, it is a piece of root or a branch that is supposed to grow again at another point. The size of the rice should not exceed five centimeters. The pad is now cut slightly. Use a flat and sharp knife and be careful not to cut too deep into the wood.
The rice is cut into a wedge shape at the lower end and should fit into the cut in the base. The rice should lie exactly on the surface and touch it with its barkless side. In order to keep the rice and the base well together, thin wire or an elastic band is used. After about two months, the rice will start to grow.
You should only remove the tape after about a year.
Wählen Choose underlay
❷ Cut rice
❸ Fix rice and underlay
In this case, a stump less than five millimeters thick serves as a base. This is cut off horizontally at a height of about ten centimeters. The rice should be thinner and only about half the length of the pad. With a roughly two centimeter deep cut, split the underlay in half. The rice is cut into a wedge shape and pushed into the gap. If the rice and the mat are congruent, the fixation is also carried out again with wire or tape.
The fixation can be removed after about a year. The underlay will appear visibly thicker at the place of the grafting than the rest of the trunk. This largely grows over the years.
