When does chrysanthemum bloom? Pictures of chrysanthemum

1. Flowering time

People often call chrysanthemums autumn chrysanthemums, so most varieties bloom in autumn. However, there are some cultivated varieties that bloom earlier or later, such as summer chrysanthemum, which blooms in May and September of the lunar calendar, and winter chrysanthemum, which blooms from December to January of the following year. Of course, but some are open in mid-to-late September, and the later ones are open in October-November.

2. How to promote flowering

1. Control the daylight hours: Unlike many plants, chrysanthemum is a short-day flower. Therefore, if you want it to bloom, you must control the light hours, otherwise the flowering period will be delayed. Generally speaking, in the 45-55 days before flowering, it is necessary to ensure 14 hours of darkness every day. At this time, strict shading is required and the temperature should be controlled at around 25-30℃.

2. Appropriate fertilization: If you want the chrysanthemums to bloom, it is essential to supplement nutrients. Especially after the flower buds appear, adding a little phosphorus and potassium fertilizers can promote flowering of the plant. Usually, you should also pay attention to controlling the amount of nitrogen fertilizer, otherwise the plants will easily grow too tall and it will also affect flowering.

3. Reduce watering: Chrysanthemums are more likely to use nutrients for growth in an environment with sufficient water. Only by controlling the water properly and making it feel "thirsty" will it seek to bloom and reproduce. Therefore, before flowering, keeping it dry appropriately can also help promote flowering.

4. Pruning: As the chrysanthemum grows, it will become more and more lush, which will consume a lot of nutrients and make it more difficult for the plant to bloom. Therefore, pruning is necessary. Generally, the plants should be topped off two weeks after being potted, and the buds should be thinned out in time to ensure a concentrated supply of nutrients.
