1, sowing date; There are many kinds of coriander, and heat-resistant coriander should be planted when the temperature is above 30 degrees. If it is below 30 degrees, you can broadcast ordinary coriander. It's best to wait until it's below 30 degrees, because it's a cool vegetable and it's too hot to grow after germination.

2. Prepare flowerpots; Don't use too small flowerpots to grow coriander. It is best to choose a long flowerpot. The bigger the flowerpot, the better to avoid crowding. The depth of the flowerpot is only ten centimeters because its root system is not very developed.

3. Seed treatment; Coriander seed shell is thick, so it will affect germination. You can soak the seeds in water for 10 hour, then rub them open and break them in half, or just put the dried seeds on the ground and step on them in half.

4. Sowing method; When planting coriander, don't sow seeds closely. After sowing, be sure to water the soil to keep it moist. When the temperature is low, it should be covered with film to keep warm and cultured in a cool place. After germination, you should bask in the sun in time.
