Summer dahlia cultivation methods and precautions

Dahlia is a flower that many people like to plant. It has bright colors and a long flowering period, and is known as the "flower of a thousand faces." The temperature is high in summer. Here are some tips and precautions for growing dahlias in summer.

1. Shading measures

Dahlias like light and are not shade-tolerant, so they need to be placed in a sunny place for daily care. The plant needs to receive more than 6 hours of sunlight a day to ensure that it grows healthily and has large and colorful flowers. But it is afraid of strong sunlight, so we must also take shade measures in summer.

2. Humid environment

Dahlias have a relatively high demand for water, but the temperature is high in summer. If the ventilation is not very good, watering is excessive, and the soil is in a hot and humid environment, the dahlia bulbs will be easily damaged. Therefore, you must pay attention to watering, do it under well-ventilated conditions, and try to spray more water and water less. In summer, you can spray water mist around the dahlia plants and on the leaves in the morning and evening. Pay special attention to the ventilation of the environment and do not let water accumulate in the pots.

3. Reasonable fertilization

Dahlia is a variety that likes fertilizer. It needs nitrogen fertilizer once every half a month. But during the flowering period of dahlia, it needs to be supplemented with phosphorus and potassium fertilizer every 10 days or so. However, when the temperature exceeds 30 degrees in summer, dahlia will enter a state of slow growth. At this time, fertilization should be reduced, and special attention should be paid to the concentration of fertilizer . It must be diluted very low, it is best to dilute it more than 1500 times with water before watering.

4. Provide good ventilation

In summer, dahlia plants should be placed in a semi-shaded, ventilated environment where they can receive scattered light but not too much shade, which is conducive to the growth of branches and leaves and helps the plants to produce flower buds. In addition, excess water can evaporate in time and will not cause yellow leaves and root rot.

5. Notes

When the weather is dry and hot, you can spray water around it more often, about 2 times a day, which can replenish moisture, reduce temperature and increase humidity. When growing dahlias in summer, in addition to paying attention to environmental ventilation, we must also pay special attention to the ventilation of the soil. If our soil becomes compacted, we must do a good job of loosening the soil to keep it loose. Only dahlias with healthy bulbs can safely survive the summer and bloom normally.
