When will the spring be sown?

The best time for seed sowing is between March and June of each year. During this period, the temperature rises from the cold winter to the warm spring, and the sun is gradually sufficient but not too strong. In terms of physiological habits, the seeds suitable for European primrose spring germinate, grow and grow, and can also catch up with the progress of flowering.

The sowing time of European primrose spring

1. Air temperature

The best sowing time for European primrose spring is between March and June each year. This kind of plant is a kind of plant that likes a cool environment and is less heat-tolerant, so during the period from March to June, the spring blossoms and the winter cold has faded, but the rising temperature will not rise to 30 degrees Celsius, which affects growth. Suitable for sowing.

2. Sunshine

Oufuchun needs to receive sufficient sunlight during its growth and development so that it can carry out photosynthesis, branch and grow leaves, and finally flourish. Therefore, in this period of time, the sun gradually brightens up, and the daily light time also gradually increases, but not to sunburn European spring, is the appropriate intensity.

3. Florescence

Another advantage of Oubaochun sowing between March and June is that it can catch up with the flowering period. After a year of development and maintenance, the sown European primrose grew and matured, just in time to catch up with the European primrose florescence from January to April of the following year. The blooming period is very long and the flowers are bright, so it has a high appreciation value.

4. Physiological habits

In terms of physiological habits, European primroses are lagging behind in March-June, and the seeds harvested at this time contain a lot of nutrients and stored nutrients, which can be sown quickly after picking, so as to prevent the nutrients in the seeds from being consumed for a long time.
