The calming effect of valerian (valeriana) is widely appreciated. It also makes little stress to multiply the plant and thus always have a valuable medicinal and attractive ornamental plant in stock. The different ways of multiplying valerian are now presented in more detail.

Propagation is possible by:

  • ground shoots
  • Absenker
  • stock division
  • seed

The different types of propagation presented

❍ Propagation by soil shoots

Multiplying valerian by soil shoots is a very simple and promising method, which requires a little patience from the amateur gardener.

No further action is required, because the plants independently develop soil shoots. If new shoot tips appear next to the mother plant, they are allowed to grow first. Once the ground shoots have reached a height of about ten centimeters, the plant lover can intervene, cut off the ground shoots and dig them out. The shoots can be replanted at the desired location and, like the mother plant, are then cultivated independently.

❍ The increase by subsidence

The propagation by lowering may be a little more complex for the hobby gardener, but it promises good results and is also very quick. First, a strong side shoot is selected that extends to the ground.

" Attention: The side shoots must not be kinked, otherwise the nutrient supply will be interrupted.

About ten centimeters after the tip of the shoot, a section of the shoot is led into the ground, covered with earth and weighed down so that the sinker does not snap out of the ground. The remaining shoot tip should grow vertically upwards and is therefore attached to a wooden stick inserted into the ground. Roots now form on the underground section of the shoot. After about four to eight weeks, it should be ready. The sinker can now be separated from the mother plant and planted as an independent plant at the desired location.

❍ Multiplication by stick division

If the later plant is to be used for medicinal purposes, propagation by stick division is recommended, because this method guarantees the cultivation of genetically uniform valerian plants. For the cane division, the plant's mother cane is cut into about ten to twenty individual parts.

" Tip: The lower stem of the plant, provided with roots and buds, is called the mother stick.

The individual parts of the plant are then replanted. For group plantings, a distance of about 30 centimeters must be maintained.

" Tip: The floors should be divided in spring. If they are propagated in autumn, the seedlings are not yet robust enough and could freeze to death in winter.

❍ Propagation by seeds

With seed propagation, direct sowing is just as possible as pre-cultivation. The pre-culture of valerian promises better chances of success.

What happens in the pre-culture?
In the preculture, the seed is not sown on the spot in the field, but initially in small growing vessels. This can already happen in late winter. Valerian needs constant ambient temperatures of 18 to 20 degrees for germination. Covering the plant pots with foil promotes germination. After germination, the temperature can be reduced to about 16 degrees. The growing plants should be transferred several times to larger plant pots. In summer, the valerian plants have developed to such an extent that they can be used in beds or in the herb garden.

Planting should take place at the latest at the end of August so that the young plants can develop well before winter.

" Tip: Valerian seeds retain their germination ability for several years if stored in a cool, dry place.

Direct sowing
Direct sowing is less complex. One disadvantage is the susceptibility of the seedlings. Rain and heat can harm the seedlings and the chances of success are rather moderate.

Sowing takes place in rows, the distances between which should be about 40 centimeters. After spreading the seeds should be pressed. The seeds should be watered regularly and weeds should be removed from the bed.

" Tip: If the seedlings grow too densely, they should be separated so that the young plants do not interfere with each other in their growth.
