When is it better to plant dahlias
You may not know when it is better to plant dahlias and the green plant flower planting content about the planting time and flowering period of dahlias. Let's take a look together!
Currently, it is during the Chinese New Year period. As the Spring Festival ends and spring approaches, the weather will gradually warm up. Flower enthusiasts who enjoy growing flowers can plant a few dahlias in their gardens. Simply bury the tubers in the soil, water them, and take care of them slightly, and they will quickly grow into a large cluster, blooming beautiful and large "flower bouquets" in the summer. Let's learn about the methods of planting and caring for dahlias in early spring~
Planting Time
The mild temperature of spring is very suitable for sowing flowers. Many flower varieties need to be planted in spring, and dahlias are no exception. The propagation of dahlias mainly relies on sowing their robust tubers, and the most suitable temperature for germination of the tubers is between 15-25 degrees Celsius. Therefore, most regions need to start sowing in March to April of spring. In some hot southern regions, sowing can start from February, while in some cold northern regions, it is necessary to wait until the temperature stabilizes above 15 degrees Celsius, and sowing can take place in April to May.
Planting Soil
The powerful tubers of dahlias can store a large amount of nutrients and moisture, so the requirements for soil are not very high. Both fertile and relatively poor soils can be used to plant them. If planting directly in the garden, garden soil can be used. However, after the tubers have germinated, it is necessary to fertilize regularly to supplement the plant with nutrients. If planting in a pot, because the pot can only hold a limited amount of soil, it is better to use good quality nutrient-rich soil, otherwise the plant may suffer from malnutrition and growth obstruction.
Choosing Tubers
When buying dahlias tubers, choose those with full flesh, multiple buds, and no scars, insect holes, or rotten spots on the surface.
The tubers of dahlias need some processing operations before planting. If the tubers are too large, they need to be cut with a knife, dividing the large tubers into small ones, ensuring that each tuber has full buds. Then, apply a fungicide such as carbendazim or wood ash to the cut surfaces to disinfect them. Place the tubers in a cool and well-ventilated area to dry the wounds before planting.

For potted dahlias, prepare pots and soil. The pot should not be too shallow, or the plant may fall over later. Bury the tubers in the soil, but do not completely cover the dahlia with soil. Leave some buds on the soil surface to help the dahlia grow faster. Planting dahlias in the ground is even simpler. There is no need to prepare a pot. Just shallowly bury the tubers in the soil and water them.
In warm weather, it takes about 10 days for the tubers to sprout from the soil. Sometimes many sprouts will emerge, and it is necessary to pinch off some of the sprouts when they grow to about 10 centimeters to prevent the plant from becoming too scattered and to grow stronger quickly.
Watering
The root system of dahlias can absorb and store a large amount of water, so the plant has strong drought resistance and does not need to be watered frequently. However, during the seedling stage, when the tubers have not yet developed, more watering is needed. Water when the soil surface is dry. As the plant grows, watering should be gradually reduced, as overly moist soil can cause tuber rot. For potted dahlias, water only when the potting soil is completely dry and the pot feels light; for ground-planted dahlias, water only when the soil around the plant is dry.
