How to plant and manage dahlias
Do you know about these? Here is an introduction to the green plants and flowers on how to plant and manage dahlias and the tips for caring for dahlias. Please see the detailed introduction below.
Dahlias, also known as大理花 (Dali flowers), have a long blooming period, from summer to autumn, and are extremely beautiful when in bloom. There are currently several methods for planting dahlias, including seed sowing, cutting, and division. The seed sowing method involves spreading seeds on the soil and then covering them with soil and watering. The cutting method is usually carried out in summer, and watering should be done promptly after cutting. The division method involves dividing the tuberous roots of dahlias first, and then planting them in pots or in the ground. Among these methods, division has the highest survival rate. Let's talk about it in detail below.
1. Seed Sowing
The seed sowing method is frequently used when planting dahlias. Sow some plump dahlia seeds on the soil in March to April; cover them with a thin layer of soil 0.5 centimeters thick, then water thoroughly to keep the soil moist. Seedlings can emerge in about a week. Be careful not to expose them to strong sunlight.
2. Cutting Method
Choose fertile and loose soil and carry out cuttings in summer. Remove the lateral branches of dahlias, leaving 3 nodes; insert 2 nodes underground and leave 1 node above the ground. Water immediately after cutting. The cuttings of dahlias generally take 3 weeks to root.
3. Division Method
The division method has the highest survival rate among the dahlia planting methods and is relatively simple. Divide the tuberous roots of dahlias, 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, making sure to water "when dry and wet," not too dry or with standing water. Seedlings can emerge in a week.
4. Daily Maintenance
Dahlias prefer a semi-shaded and cool growing environment. Place them in a location with scattered sunlight and good ventilation, and control the daily sunlight exposure to 10-12 hours. The temperature requirements are not high, keeping it between 8-35°C is fine. Dahlias enjoy fertilizer, and sufficient nutrient supply can make the flowers larger and more vibrant. Generally, fertilize every 10-15 days during the seedling stage, and every 7-10 days after the bud formation, stopping fertilization when the buds show color and during the high-temperature season. In terms of water management, dahlias are not drought-tolerant and fear waterlogging. When watering, make sure not to water when dry, and water thoroughly when watering, preferably when the soil is dry and wet.
The above is a comprehensive explanation of how to plant and manage dahlias and the tips for caring for them. I hope this can help you.
