What are the cultivation methods and precautions for dahlias

How to grow dahlias

Dahlia belongs to the Asteraceae family. It is generally planted by division, cutting and sowing. When breeding, it is necessary to start from the following six aspects:

1. Temperature

Dahlias prefer a cool growing environment, but are not cold-resistant. When caring for them, the temperature needs to be kept between 15-25 degrees, which is more conducive to their growth.

2. Lighting

Dahlias prefer a semi-shaded growing environment, so they need appropriate sunlight when caring for them, and the lighting time should be maintained at about 10 hours, and strong light exposure needs to be avoided.

3. Soil

Dahlias need suitable soil when planting. It is best to use loose, fertile and well-drained sandy soil.

4. Watering

Dahlias require more water when being cared for, because they have many leaves and flowers, so they should be watered in time to avoid the soil drying out due to high temperature.

5. Fertilization

Dahlias need to be fertilized during the seedling stage, and they need to be fertilized every 10-15 days. Diluted fertilizer can be applied. After the flower buds grow, the amount of fertilizer needs to be increased to ensure sufficient nutrients.

6. Pruning

Dahlias need to be pruned in time during the growing season. The top buds need to be retained and the other axillary buds should be cut off, so that the nutrients can be more concentrated.

Dahlia cultivation precautions

When growing dahlias, you need to be careful to avoid strong light exposure in the summer and waterlogging in the rainy season. A good ventilation environment is needed during maintenance, which can avoid the occurrence of diseases and pests to a certain extent.
