How long does the cosmos flower last?

1. How long is the flowering period?

The flowering period of cosmos is relatively long. It can bloom from May to June, and the flowers will continue to bloom until frost. Its peak flowering period is from July to September and it has high ornamental value. Its flowering period can be controlled by planting time. If you want it to bloom early, you can plant it in early spring or grow seedlings in a greenhouse.

2. Methods for controlling flowering period

1. Planting time: If you want to use the sowing method for reproduction, you can do it in April. It will bloom in about 3 months. If you want the flowers to bloom earlier, you can increase the temperature appropriately or sow them in summer.

2. Daily maintenance: During the maintenance period, reducing the time it receives light can also change its flowering period and allow it to bloom earlier.

3. Maintenance during flowering period

1. Watering: Do not water too much during the flowering period, as long as the soil is slightly moist but not dry. If you water too much, it will easily shorten the flowering period.

2. Fertilization: Appropriate fertilization is needed before flowering to maintain the flowering of the plant. Appropriate topdressing is also needed during the flowering period to help more flowers bloom.

3. Light: When it is in bloom, the sun is strong. If the light is too strong at noon, you need to move it or block some of the strong light.
