How to sow flower seeds that are especially small

Sowing especially small seeds also falls into outdoor sowing and sowing in pots. The method is the same as for sowing annual or biennial herbaceous flowers, but note that for outdoor sowing, after the seedbed is leveled, the top layer of soil should be sifted through a fine sieve, because coarse particles leave large gaps and tiny seeds easily fall into them, which affects the germination rate. Depending on the amount of seed, using a clay pot or a large wooden box filled with soil for sowing is also a method often used by amateur flower growers. Line the bottom of the clay pot or wooden box with tile pieces or broken pot pieces, put in coarse soil, place a layer of fine soil sifted through a fine sieve on top, press it flat with a small wooden board, and then sow.

Fine seeds are not easy to scatter evenly, so before sowing you can mix the fine seeds with an appropriate amount of fine garden soil, potting soil, plant ash, or fine yellow soil, and scatter them evenly over the seedbed by broadcasting; no additional soil cover is needed. After sowing, press lightly with a wooden board so that the soil and seeds are in close contact. For outdoor sowing, cover with some rice straw in time after sowing to prevent later rain from washing them away. Water after sowing; for outdoor sowing you can water with a watering can, but be careful not to spray too much at once, because too much water will make the seeds float up and gather in a clump. Spray water several times so that the moisture slowly seeps in. For pot sowing, you can use the pot immersion method: immerse the lower part of the pot in water so that water slowly seeps in through the drainage hole at the bottom until the pot soil is moist. Then place it in a cool, ventilated place. Cover with a glass lid, and later, when the pot soil dries out, use a fine sprayer to spray and water.
