How to sow evening primrose

Evening primrose can be used to cultivate seedlings by sowing, and its reproductive ability is relatively strong. In northern areas, it is mostly sown in spring, and in other places it is also suitable for sowing and breeding in autumn. So, how does evening primrose seed? Today, Xiaobian will tell you about the planting method of this plant.

1. Substrate disinfection

Before sowing, we need to disinfect the culture medium. It is recommended to put the selected soil into the casserole and stir fry it. This will not only achieve the effect of sterilization, but also eliminate harmful substances such as eggs.

2, warm water soaking

After treating the culture medium, we also need to soak the seeds. The seeds are usually soaked in warm water for about 3-10 hours until they swell.

3. Sowing process

Because this kind of flower seed is relatively small, it is generally difficult to pinch it directly by hand to sow. We can use toothpicks to assist in this by dipping one end of the toothpick in water and then using the wet part to remove the seed from the surface of the substrate. Then cover with a layer of culture soil about 1 cm thick.

4. Dip basin hydration

It is not recommended to water the seeds, but in order to achieve the purpose of watering, we can complete it by dipping the pot. Put the seed pot into a certain depth of water, and then the water will slowly soak up through the pot until the soil becomes moist.

5. Key points of management

If it is autumn sowing, when the temperature drops sharply, it is recommended to wrap the flowerpot with plastic film to achieve the purpose of heat preservation and moisture retention; when the seed sprouts, in order to promote ventilation and ventilation, the plastic film should be released in time, and it should receive a certain amount of light in the morning and evening every day, so as to ensure that the seedlings can thrive.

When most of the seeds emerge, they should be thinned in time, and the weak seedlings need to be pulled out. At the same time, in order to ensure that the seedlings can have enough air for growth, some seedlings should be pulled out appropriately for places that grow too densely. When most seedlings have more than 3 leaves, they can be transplanted into pots.
