Cosmos is not used for other sown flowers and plants, it does not like to be sunburned in the early days after sowing, so it should be placed in a cool and ventilated place to let it grow slowly. After germination, it can be exposed to a small amount of sunlight, which can be sunned in the morning or evening. This is more conducive to growth.

After the cosmos grows to five centimeters high, it enters a rapid growth stage. After that, it must not be watered too much or fertilized, otherwise it will affect its normal flowering. Wait until the surface of the soil is dry and then water it. Fertilize with flower nutrient solution. After diluting with water, irrigate the flower roots in a small amount. Fertilize more frequently, but don't irrigate too much each time. This will form nutrients that will accumulate thick and thin. After flowering, the flowering period will last longer.
