For four seasons primrose, it is suitable for shallow basin with good drainage
Choose healthy seeds with full seeds for sowing. In addition, it should be noted that the seed life of four seasons primrose is relatively short, so it needs to be sown immediately after harvesting. If you don't broadcast them immediately, you can put them in the room to dry, and seal them up and put them in the refrigerator.
The rotten leaf soil, peat soil, stable fertilizer soil and sand soil are mixed evenly according to the ratio of three to one to one as the culture soil. In addition, an appropriate amount of fertilizer can be added, which is not only conducive to the germination of seeds, but also conducive to the growth and development of subsequent plants.
In general, choose July or August for sowing
Put the prepared soil into the container, without filling too full, a distance of one or two centimeters from the basin mouth. Then the seeds are sown into the soil. Because its seeds are very small, so there is no need to cover a layer of soil.
The next step is the control of various conditions. First of all, the temperature, controlled at 15 to 20 degrees Celsius, is more conducive to its germination. In addition, humidity and sufficient water are very beneficial to its sprouting. In order to achieve this goal, you can cover the container with a piece of glass or plastic film to moisturize.
Keep the conditions right, wait about a week or two, and it will sprout. When the seedlings grow about five true leaves, they can be planted.
