1、 Is autumn maintenance important

For dahlia, autumn maintenance is relatively important. Because it blooms in summer and autumn, it will bloom most vigorously around September, so the early maintenance method is related to the quality of flowering. By the end of autumn, the flowering period is basically over, and the maintenance after flowering is also more important

2、 How to raise in autumn

1. Temperature: specifically, about 20 degrees is the most conducive to flowering. In the early autumn, ensuring the temperature is conducive to good flowering quality. At the end of autumn, as the temperature decreases slowly, ensuring the appropriate temperature can not cause the dahlia to be damaged by freezing, but also lay a good foundation for safe winter

2. Water: dahlia is not drought resistant, so in order to promote flowering, we must ensure sufficient water supply. However, it is afraid of waterlogging, so it can be poured according to the principle of "watering after drying, and watering after watering". However, by the end of autumn, the temperature will decrease and the demand for water will decrease accordingly, so the amount of watering should also be adjusted

3. Fertilizer: fertilizer can be used properly once a week, and liquid fertilizer with lower concentration can be used. However, there is basically no need at the end of autumn

4. Light: sufficient light can help flowering. It is best to ensure sufficient scattered light throughout the autumn, which can promote flowering in the early stage and help accumulate nutrients for winter in the later stage
