When is the best time to plant dahlias?

Dahlia, also known as sweet potato flower, traditionally, the common colors of dahlia include pink, yellow and bright red. With the development of horticultural technology and the introduction of varieties, there are now more hybrid dahlia varieties on the market, and the flower colors of these new varieties are more diverse. So when is the best time to plant dahlias?

When is the best time to plant dahlias?

In order to improve the survival rate and growth effect, spring is the best planting time, approximately between March and April. The climate and temperature during this period are more suitable, which is conducive to seed germination and seedling growth, and is also easier to manage.

Dahlia daily cultivation tips

1. Lighting management

Dahlias prefer mild light conditions, and strong direct light may cause sunburn, dehydration of the leaves, and even wilting of the flowers. Therefore, direct exposure to the sun should be avoided to ensure that the plants receive gentle scattered light.

2. Water supply

Dahlias love moist conditions, but too much water can cause roots to suffocate and rot. Therefore, watering needs to be timely and appropriate to keep the soil moderately moist. The timing of watering is usually determined based on the dryness or wetness of the soil to ensure that the plants get the water they need. In case of continuous rainy days, it is necessary to take measures to avoid rain and enhance ventilation to maintain a good growing environment.

3. Fertilization strategy

Due to their rapid growth rate and long flowering period, dahlias have high fertilizer requirements. Proper fertilization is the key to ensuring healthy plants and abundant flowers. During the peak growth period, diluted cake fertilizer is generally chosen for fertilization to avoid root burn problems. As the flowering period approaches, increase the use of phosphorus and potassium fertilizers, and spray potassium dihydrogen phosphate solution on the leaves to promote flower bud differentiation and improve the quality and yield of flowers.

4. Temperature control

Dahlias are sensitive to extreme temperatures, and the most suitable growth temperature is around 20℃. Temperatures that are too high can inhibit growth, while temperatures that are too low can cause frost damage. Therefore, when the temperature fluctuates greatly in spring, it is necessary to do a good job of insulation; in early summer, cooling measures should be taken, such as placing the plants in a well-ventilated and cool place, and spraying water in time to lower the ambient temperature.

In short, the best time to plant dahlias is generally in spring. Through these meticulous management measures, a suitable growing environment can be created for dahlias.
