Spray and humidify around the flowerpot every afternoon when it is hot in summer.

Dahlias go into semi-dormancy in summer, so you must pay attention to these points in order to get through the summer safely:

1. Root maintenance: dahlias have large fleshy roots, which are avoid dampness and heat in summer, and are easy to rot in high temperature weather, so watering should be dry and wet, more loose soil should be breathable, and water in the basin should be cleaned up in time after heavy rain.

After finding rotten roots, you should immediately cut off the broken roots, change pots and change soil, or "amputation" cuttings to reproduce.

2. Shade maintenance: avoid strong light in summer, outdoor cultivation is most likely to be sunny after rain, it is necessary to pull the sunshade net in time to protect.

3. Pruning and maintenance: Dahlia is happy and afraid of boredom. When the branches and leaves are too dense in summer, the branches should be trimmed and sparse, and the lateral branches should be kept at 3-4 nodes. After flowering, the flowering branches and withered branches should be trimmed, and the main stem should be cut to 15~25cm.

4. Disease and pest protection: Dahlia is most likely to get gray mold and powdery mildew in summer, the flowers turn brown and irregular, and the edges of the leaves are spotted, withered and softened. When these phenomena occur, the diseased branches and diseased plants should be cut off and destroyed in time. And use 50% carbendazim wettable powder 500 times liquid spray control.

That's all Huahua introduced today.
