How to sow evening primrose seeds? Latest planting method explained in detail
Evening primrose can be grown into seedlings by sowing, and its reproductive capacity is relatively strong. In northern regions it is mostly sown in spring, while some other places are also suitable for sowing and propagating in autumn. So, how do you sow evening primrose? Today, the editor will explain this plant's sowing method for everyone.
1. Substrate disinfection
Before sowing, we need to disinfect the culture substrate. It is recommended to put the selected soil into a sand pot and stir-fry it. This can not only achieve a sterilizing effect, but also eliminate harmful substances such as insect eggs.
2. Soaking seeds in warm water
After handling the culture medium, we also need to soak the seeds. Usually, warm hot water can be used to soak the seeds for about 3-10 hours, until the seeds swell.
3. Sowing process
Because this kind of flower seed is relatively small, it is generally difficult to pick it up directly with your hands for sowing. We can use a toothpick to assist. The method is: dip one end of the toothpick in water, then use the moistened part to pick up the seeds, and then sow them on the surface of the substrate. Next, cover with a layer of culture soil about 1 cm thick.
4. Bottom watering to replenish moisture
For replenishing water to the seeds, watering is not recommended, but in order to achieve the purpose of watering, we can do it by the bottom-watering method. Place the flower pot with the sown seeds into water of a certain depth, and then the water will slowly seep up through the flower pot until the pot soil becomes moist.
5. Key management points
If sowing in autumn, when the temperature drops sharply, it is recommended to wrap the flower pot with plastic film to achieve the purpose of heat preservation and moisture retention; after the seeds sprout and the seedlings break through the soil, in order to promote ventilation and air permeability, the plastic film should be removed in time, and they should receive a certain amount of light in the morning and evening every day. Only in this way can the seedlings grow robustly.
When most of the seeds have emerged, thinning should be carried out in time. Diseased and weak seedlings need to be pulled out. At the same time, in order to ensure that all seedlings can have enough growing space, some seedlings should also be appropriately pulled out from places where they are too densely grown. After most of the seedlings have spread more than 3 leaves, they can be transplanted into pots.
