Rosemary is one of the most popular culinary herbs. We will show you how you can easily propagate the aromatic subshrub yourself.
From the multiplication of the Rosemary (Rosmarinus officinalis) is generally not advisable. It simply takes too long for the seed to germinate and for the tender seedlings to push themselves to the surface of the substrate. Under optimal conditions with high germination temperatures of 25 to 30 ° C, it takes six to eight weeks for the first green to stretch out into daylight. This variant is therefore more for the patient who would like to expand their rosemary stock. If a rosemary plant already exists, it can be propagated much better and faster using cuttings. We'll show you how to do this and what to watch out for.
Propagation of rosemary via cuttings
- Choosing the right season: Spring is usually best for propagating cuttings. At this time of year the plants sprout fresh. The tender young shoots are particularly easy to take root. In addition, the higher light supply in spring favors the multiplication of rosemary via cuttings. A bright and warm place on the windowsill is ideal.
-
Cutting the cuttings: The shoots that serve as cuttings should have a minimum length of 5 cm, but a maximum of 10 cm long. It is important to note that the shoots do not yet have any rooting in the lower area - this would make rooting unnecessarily difficult and lead to reduced rooting success. Prefer a sharp knife to cut the cuttings. Shearing causes bruises at the interface, which are not exactly conducive to the formation of new roots on the cutting.
-
Choice of substrate: Special substrates are available for propagating plants using cuttings. This is characterized by a low nutrient content. They also have a very airy, loose structure, which is what the delicate, newly formed roots of the Cuttings make it easier for them to penetrate the pot and also provide them with sufficient oxygen will. It is best to first fill the substrate into propagation plates or small degradable paper pots, this saves space on the You can still repot the small plants after the successful completion of the planting in the window sill and in a larger container Rooting.
- Bring the cuttings into the ground: Do not insert the cuttings too deeply into the substrate. Only the first centimeter above the interface should be in the substrate. If necessary, you should remove the needles at this point. When these are in the substrate, they start to go moldy. After the cuttings have found their way into the substrate, water them well. You shouldn't save on water here.
-
Create the perfect environment: In addition to a warm and bright place on the windowsill, cuttings attach great importance to the so-called tight air. To do this, cover the propagation vessels with a transparent lid. The propagation boxes, which are available in different variations and price ranges and consist of a base and a removable lid, are practical. If you just put it in a single pot, you can also put a cut-off PET bottle over it. It has the following meaning: The cuttings do not yet have roots with which you can draw water from the substrate. The increased humidity that you create with the cover prevents excessive evaporation via the needles of the rosemary and threatening wilting.
Wean the cuttings: After two to three weeks, the first roots will form on the cut rosemary cuttings. Now it is time to slowly take the spoiled young plants out of their damp comfort zone. In the long term, there is a danger of life-threatening fungi attacking the rosemary due to the high humidity. It is advisable to get used to the drier ambient air so as not to throw the cuttings into cold water. For example, only remove the lid at night and leave it on the plants as usual during the day. If you take the lid off during the day, watch the dainty plants a little more closely. If the fabric becomes too soft and there is a risk of sagging wilt, it is better to cover it again with the transparent lid. Alternatively, you can moisten the rosemary pupils with the fine jet of water from an atomizer.
