If you want to grow this kind of flower well, you must understand it in advance.

Four-season management of dahlias

1. Spring management of dahlias

Dahlias are suitable for being placed on east- and south-facing balconies in spring, and this season is a good time to repot them. When repotting, the soil should be rich in humus. Dahlias should be placed in a sunny place in spring, and water should not be supplied too late to keep the soil moist.

2. Summer management of dahlias

Summer is the time of the year with the highest temperature. It should be placed in a cool and ventilated place in this season. It is afraid of high temperatures. If it is exposed to direct sunlight, the dahlia will die. When the weather gets cooler, you can slowly move the dahlia to the sun for cultivation.

3. Autumn management of dahlias

After entering autumn, dahlias should be provided with sufficient water and sunlight, and topdressing should be applied in time. Topdressing should mainly be with high-quality potassium fertilizer. In addition, after the autumn cools down, dahlias will enter a dormant period. At this time, the water supply should be reduced, and the dead stems and leaves on the ground should be cut off.

4. Winter management of dahlias

The dahlia plant will enter a dormant period in winter and has poor cold resistance. At this time, the flower pot should be moved to a warm room. The minimum indoor temperature should not be lower than three degrees, otherwise the dahlia will rot and die.
