Generally, when sowing flower seeds, it is necessary to drench the sowing soil in advance, then sow or sow it on the soil surface, and then cover it with fine sand. The thickness of covering soil varies with the size of seeds. If the seeds are small, only thin soil can be covered or no soil can be covered. Generally, the thickness is about 1 cm. When sowing in spring, you can keep warm and moist with plastic film, but not in summer. Generally, it is necessary to sow in a well-lit place. In summer, you can sow in a semi-shady place or in a shady place, and remove the shade in time after the seedlings are unearthed.

Take rose varieties as an example:

About the choice of soil:

The germination rate of rose seeds is low, so the soil used for general sowing needs to be loose, breathable and strong in water retention. The commonly used soil is a mixture of vermiculite, peat, water moss, perlite and snake sawdust. , conditional can be configured by yourself; Unconditional general weak acid soil can also be used, but there must be no foreign bodies in the soil.

(such as stones, broken bricks, glass, etc.). ).

Step 1: Soak the rose seeds in warm water of about 40 degrees, cool and soak for 4-6 hours, and take out the seeds. Soaked seeds germinate easily.

Step 2: put the seeds into the soil (note: the soil needs to be loose, breathable and have good water retention capacity). Generally, 5~8 seeds can be planted in each container. After germination, leave a stronger one according to the growth status of the seedlings; Leave 1~3 seedlings between seedlings after germination as appropriate. After sowing, the container should be covered with plastic wrap (plastic wrap can also be used for convenient bags), and several holes should be punched in the plastic wrap to breathe. Put the container in the sun and keep the temperature at about 20 degrees. Most seeds can germinate after a week. After germination, the seedlings are strong and transplanted to the ground.
