Dahlia is also known as大理花, and its blooming period lasts a long time, from summer to autumn, extremely beautiful. There are currently seed sowing, cutting, and division methods for planting dahlias. The seed sowing method is to scatter seeds on the soil and then cover them with soil and water; the cutting method is usually carried out in summer, and water should be provided in a timely manner after cutting; the division method involves dividing the tuberous roots of the dahlia first and then planting them in pots or in the ground. Among them, the division method has the highest survival rate. Let's talk about it in detail below.
1. Seed sowing
The seed sowing method is used more often when planting dahlias. Scatter some plump dahlia seeds on the soil in March to April; cover them with a thin layer of soil 0.5 cm thick and then water them thoroughly to keep the soil moist. The seedlings can germinate in about a week. Be careful not to expose them to strong sunlight.
2. Cutting method
Choose fertile and loose soil and perform cuttings in the summer. First, remove the lateral branches of the dahlia, leaving 3 nodes; insert 2 nodes into the ground and leave 1 node above the ground. Water immediately after cutting. The cuttings of dahlia usually take three weeks to root.
3. Division method
The division method is the one with the highest survival rate among the dahlia planting methods and is relatively simple. Divide the tuberous roots of the dahlia, ensuring that each divided root has 3 terminal buds; if there are no terminal buds, new plants will not grow. Then you can plant them in pots or in the ground. Water after planting, and when watering, it should be "dry-wet," not too dry or waterlogged. Seedlings can grow in a week.
4. Daily maintenance
Dahlias prefer a semi-shaded, cool growing environment. Usually, place them in a position with scattered sunlight and good ventilation, and the daily sunlight time can be controlled at 10-12 hours. The temperature requirement is not high, controlled between 8-35℃. Dahlias like fertilizer, and sufficient nutrient supply can make their flowers larger and more colorful. Generally, fertilize every 10-15 days during the seedling stage, and every 7-10 days after the bud appears, stop fertilizing when the bud is colored and during the high-temperature season. In terms of water management, dahlias are not drought-resistant and fear waterlogging. When watering, do not water until it is dry, and water thoroughly when you do, preferably keeping it dry-wet.
