Propagation by Seed
The most common method of propagating Sisymbrium crassifolium is through seed. The plant produces numerous small, black seeds that can be harvested and sown in spring or autumn. Spring sowing is preferred, as the warmer temperatures stimulate germination.
To sow the seeds, mix them with a light-weight growing substrate such as peat, sand, or vermiculite. Spread the mixture evenly over the surface and water well. Keep the substrate moist but not saturated until germination occurs, which usually takes around 7-10 days. Once the seedlings have developed their true leaves, they can be transplanted into individual pots or directly into the garden.
Propagation by Cuttings
Thick-leaved Rocket can also be propagated by cuttings. This method is especially useful for gardeners who want to preserve a specific variety or ensure identical plants. The best time to take cuttings is in spring or early summer when the plant is actively growing.
Choose a healthy stem that is at least 10 centimeters long and has several leaves attached. Remove the lower leaves, leaving only two or three at the top. Dip the cutting in rooting hormone and plant it in a moist growing substrate. Keep the substrate moist and the cutting in a shaded area until roots begin to form, which can take up to four weeks. Once the cutting has adequate root development, it can be transplanted into individual pots or directly into the garden.
Propagation of Sisymbrium crassifolium through seed or cuttings is easy and effective. By choosing the method that works best for your needs, you can have a beautiful and thriving garden filled with this hardy and versatile plant.
