First, you need to prepare seeds and flowerpots. Dahlia seeds are relatively small and can be planted in seed trays or small flowerpots. When choosing a planting basin, it is necessary to pay attention to the size and air permeability of the basin, and at the same time ensure that there are drainage holes at the bottom of the basin. Next, you need to prepare the soil. Dahlia likes acidic soil with good drainage, and soft and nutritious soil such as peat soil and vermiculite can be used. In order to prevent the growth of bacteria, we can add some disinfectants to the soil.
Then spread the seeds evenly on the soil surface, then gently cover with a layer of fine soil or vermiculite, and compact the soil to make it closely combine with the seeds. Then, water the planting pots with plastic wrap to keep proper temperature and humidity. However, it should be noted that seeds need ventilation and proper watering every day to avoid the soil being too dry or wet. The seeds of Dahlia will germinate within 15-20 days after planting. At this time, the plastic wrap should be removed and placed in a sunny place. When the seedlings grow to 7-8 cm high, they can be transferred from small pots to large pots. In the process of transfer, we need to pay special attention to avoid damaging the sprouts.
In the next growth process, it is necessary to ensure sufficient water and oxygen, and at the same time, fertilize regularly before the bud appears to promote the healthy growth of flowers. In addition, during the growth of Dahlia, it needs to be properly trimmed and reshaped to make it look beautiful. ? Generally speaking, raising seedlings is a job that requires patience and skill. Through scientific and meticulous seedling raising methods, healthier and more beautiful dahlias will be cultivated, so that people can appreciate the beauty and know more about the growth laws and characteristics of plants.
