3. Watering: The chrysanthemum needs a proper amount of watering in its maintenance, but the water supply cannot be too much. Its roots cannot stand waterlogging. Therefore, it is necessary to wait until the potting soil is dry before watering. In summer, the water evaporates faster, so it is possible to properly increase the watering, and spray water once a day in the morning and evening.

4. Fertilization: The chrysanthemum is more fertile. When planting, sufficient bottom fertilizer should be applied in the pot. After that, proper topdressing should be applied in the growth and maintenance. During the vigorous growth period, fertilizer can be applied every two weeks. Be careful not to splash the fertilizer liquid on the leaves.

5, light: the process of conservation can not be a lack of sunlight, so in the growth period need to be placed in good light, exposure to sunlight, to maintain the growth required.
