Detailed introduction to the sowing methods of evening primrose

The evening primrose plant is small and delicate, and just as its name suggests, it blooms at night, visible only to the moon. Its flowering period is from June to September, with rich and brilliant colors and relatively large flowers. When the flowers first open they are golden yellow, gradually turning bright red, giving it extremely high ornamental value. In addition, it also has excellent medicinal value. So how should we grow it? The common propagation method for evening primrose is sowing. Below we will look at its sowing method and steps.

Sowing time

The flowering period of evening primrose is from June to September. In order not to miss its flowering period and to let it grow quickly, it is mostly sown in spring or autumn. For spring sowing, choose early or mid April; for autumn sowing, mostly choose mid or late October. China has a vast territory, and climate and temperature vary from place to place, so the sowing time should be adjusted according to local actual conditions. For example, in cold northern regions, temperatures are generally lower, and wind and snow do not melt easily, which can easily cause missing seedlings and broken rows. In this case, autumn sowing is better than spring sowing. In warm southern regions, spring sowing can be done before wheat sowing, when the soil has thawed, which is beneficial to seedling growth.

Site selection and disinfection

Evening primrose likes light and dislikes waterlogging, so fertile, loose, well-drained soil should be chosen. Before sowing, the soil should be disinfected. The simplest and most effective method is high-temperature disinfection, which eliminates pathogens and pests in the soil, reduces the probability of later diseases and pests, and allows the plants to grow healthily.

Seed treatment

To increase the germination rate of the seeds, before sowing first soak the seeds in warm hot water for several hours until the seeds absorb water and swell. The main thing is that the soaking water temperature should not be too high, because too high a water temperature will directly scald the seeds. A water temperature of 20-40 degrees is most suitable.

Sowing method

Evening primrose seeds are relatively small, so you need to use a toothpick or small tweezers or similar tools to place them one by one on the soil surface, then cover with about one centimeter of soil, then place the sowing flower pot into water, with the water depth at one-half to two-thirds of the height of the flower pot, allowing the water to slowly soak upward.

Later management

After sowing, when the potting soil is slightly dry, you can water with a sprayer. It is not suitable to water directly, because direct watering will make the potting soil too wet, which is not conducive to seed germination. For autumn sowing, if a cold wave and low temperatures occur, you can wrap the entire flower pot with plastic film, which helps keep it warm and moist. After the seedlings emerge, tear off the plastic film in time and place the flower pot in a sunny area so the seedlings receive sufficient light. Otherwise, the seedlings will grow extremely weak, which is not conducive to flowering during the flowering period. Once the seedlings grow more than three leaves, they can be transplanted into pots.

The above is all the content on how to sow evening primrose. After reading the above, I wonder how much everyone has learned, and whether you are confident about growing your own pot of evening primrose.
