Planting time: Mostly in the spring, avoid the summer heat and the winter cold season.
Prepare the substrate: Use soft, fertile soil, and ordinary vegetable garden soil can also be used.
Treat seeds: Soak the seeds in water and absorb enough water before sowing.
Sowing: The land is raked flat, the seeds are sown using sowing or strip sowing, and water is sprayed after covering.
Post-maintenance: to ensure that the environment is warm, you can cover the mulch film at night to keep warm, but in the daytime to properly open the ventilation.
1. Planting time
The best planting time of evening primrose is in the spring of each year, and the humidity and air temperature of the soil in the spring are conducive to the germination of seeds. Or it is also possible to sow seeds in the autumn. However, try to avoid summer and winter seasons that are too cold and hot, which is not conducive to seed germination, and it is difficult to manage later.
Second, prepare the matrix
Evening primrose likes to grow in fertile, soft soil, the adaptability to the substrate is very strong, with the characteristics of barrenness tolerance, drought tolerance, salinity tolerance, etc., in the sandy soil, loess, black soil, wasteland and other environments of the soil can grow normally, so in the preparation of the substrate can be a little free, with ordinary vegetable garden soil for planting can be.
3. Treat the seeds
Evening primrose is generally propagated by seeds, first need to soak the seeds with water for several hours, until the seeds are fully absorbed and expanded, the seeds are sown in a full and absorbed state, and the survival rate and germination rate are relatively high.
Fourth, sow seeds
Before sowing, it is necessary to fully rake the soil, and rake or select the soil of the large particles to avoid the seeds being hindered when germinating and sprouting, and can be sown by sowing or strip sowing, and after the sowing is completed, a thin layer of soil should be covered with the seeds, and then spray water to wet the substrate.
Fifth, post-maintenance
After the completion of sowing, it should be placed in a warm environment, and give it the light scattered, the temperature at night in spring and autumn is still relatively low, try to use plastic wrap or mulch film to keep warm, but also can play a moisturizing effect. When the weather is good during the day, you can properly open the ventilation, and spray a small amount of water to maintain the moisture of the soil.
