How to grow chrysanthemums in spring

1. Time to leave the room

The temperature in early spring is quite changeable. If you move plants outdoors too early, they are prone to wind damage and frost damage. Therefore, the time to move plants outdoors is generally between Qingming and Lixia. To prevent it from being unable to cope with being suddenly moved outdoors, you can take appropriate measures such as increasing ventilation and enhancing light intensity.

2. Replace the potting soil

Plants growing in limited soil are prone to nutrient deficiencies, and they need to change the soil and apply fertilizer to supplement the missing nutrients and improve their nutritional conditions. The climate in spring is relatively mild, which is very suitable for repotting plants. The best loam to use is deep, loose, sandy soil rich in humus and with good drainage.

3. Fertilization techniques

In spring, plants are most afraid of excessive fertilization. Whether it is seedlings or chrysanthemums that have just survived the winter, their root systems are relatively fragile. If organic flower fertilizers that are not fully decomposed or the fertilizer concentration is very high are used, the roots can easily be burned. Therefore, in spring, the well-rotted liquid fertilizer should be fully diluted before application, and the amount used each time should be controlled, so that the amount of fertilizer applied is small but applied frequently.

4. Pruning branches

There are three types of chrysanthemum pruning: thinning, pruning and pinching. Thinning is mainly aimed at overly lush branches. Properly cutting off too dense branches can ensure that the flowers receive enough light, which is beneficial to their later growth. Shortening is to shorten overly long branches to reduce excessive loss of nutrients while stabilizing the center of gravity and preventing the plant from falling over. Pinching is to prevent the plant from only increasing in height without growing side branches, which is not conducive to the formation of flowers in the later stage.
