You have a Kolkwitzia in the garden and can't get enough of it? Then multiply the plant. You have several options to do this.

The Kolkwitzia (Kolkwitzia amabilis) is a wonderful eye-catcher in the garden in spring with its overhanging, lush flowering branches. Because of the delicately colored, shiny flowers, it is also called mother-of-pearl shrub. Propagating them is very easy for those who just can't get enough of this plant. You have the choice between three methods: propagation with cuttings, with sticks or with sinkers. All variants work well.

You can certainly also propagate Kolkwitzie with seeds. However, this procedure is tedious and does not always work. So it is better to opt for one or more other propagation variants.

Propagating Kolkwitzie via cuttings

❶ For this propagation variant, cut off a semi-lignified shoot to a length of 15 to 20 centimeters in June.

❷ Remove the leaves from the lower part of the shoot and also any flowers that may be on the cutting. There should be several leaf knots on the upper part, which you can recognize by thickening under the bark.

❸ Place the cutting halfway into a pot with potting soil and place the container in a warm, not too bright place. Now always keep the substrate slightly moist and put a transparent film or a glass plate over the pot, because that creates the right climate. Ventilate occasionally to prevent mold growth.

❹ In a warm location, the cutting quickly develops many strong roots. You can plant it outside after just three to four weeks. A sunny to partially shaded spot is favourable. The small shrub does well in normal garden soil. You can find out how to properly plant the Kolkwitzia in the garden here.

Propagating Kolkwitzie with sticks

❶ The propagation of sticks starts in February. To do this, cut off woody, one-year-old shoots on a frost-free day. Each stick should be about 6 to 8 inches long with several leaf nodes.

❷ CuttingNow make the top point straight and the bottom point at an angle to avoid confusion. If you snip the top node of the leaf, rooting will go faster.

❸ Now put the two lower thirds of the stick in a pot with potting soil. Pay attention to the direction, because incorrectly planted cuttings will not take root!

❹ The pot should now be warm but not too bright. So not at the sunny window. Alternatively, you can also place the stick in a sheltered place directly outdoors.

❺ Now you must always keep the substrate in the pot slightly moist. Outdoor cuttings should only be watered a little on frost-free days. When the first above-ground shoots appear, the young plant can be transplanted from the pot into the garden.

Propagating Kolkwitzie via sinkers

❶ With its long, curved branches, the Kolkwitzia is particularly well suited to the lowering method. For this you need a strong, he althy mother plant, which should not be too young. In early summer, pick a pliable branch from the bottom section and pull it down to the ground.

❷ Then mark the desired spot, loosen the soil and dig a ten centimeter deep channel.

❸ Now defoliate the selected branch and lightly score it in a few places with a sharp knife.

❹ Then push the sinker into the gutter, cover it with earth and weigh down the spot with a few stones to be on the safe side. The shoot tip must be visible. Then it's just a matter of waiting.

❺ You can tell that roots have formed when the sinker starts to grow. Then you can separate it from the mother plant. Then carefully dig it up and place the young plant in the new location.
