German primrose can use sowing, division and cutting ways of propagation, and sowing is one of the most common propagation methods. Now let's see these 3 propagation methods of German primrose.
German Primrose mainly propagates by sowing.
German Primrose seeds are best sown after harvest because the seed life of German primrose seeds is not very long, usually no more than 6 months. Or in dry low temperature storage conditions. Plant seeds in a seeding box or shallow bowl. Because the seeds are small, you can leave them unsoaked.
Seeds for propagating German primrose need light to germinate and are fond of moisture. Therefore, it needs to be covered with glass, covered with paper and placed in a semi-shady place. The suitable temperature for seed germination is 15-20℃. Seeds for propagating German primrose can germinate about 7-16 days after planting, but the germination rate drops significantly when the temperature is higher than 25 °C. So we should avoid the midsummer season sowing, or use an indoor sowing method.
Sowing propagation time according to their own flowering time. If you want to Flower in winter, you can sow in late spring. Sow in the early autumn and you will have flowers in the early spring.
German Primrose can also be propagated by dividing the mother plant into several parts in the spring. Transplanting can be carried out for the first time when the seedlings grow to about 2-3 leaves, and transplanting can be carried out when the seedlings grow to about 6 leaves.
German Primrose can also be propagated by cutting. The leaves with relatively vigorous growth can be selected from the mother plant, and then cut from the base to prepare loose and breathable soil. After that, the cutting can be cut into the soil, watered and moistened, and placed in a cool environment for conservation.
The seeds of German Primrose are relatively small, so it is usually used to disperse them into the soil for propagation. The soil should be loose and airy. If the soil is moist, you do not need to water it.
