Sowing time

Dahlia is generally sown in February and March of the year. The climate of this season is suitable for the growth of Dahlia. Generally, it is sown in the middle and late March when it is relatively warm. The temperature during the day is kept between 15 ° C and 20 ° C, and the temperature at night cannot be lower than 12 degrees

Selection of soil and seeds

For the soil used to cultivate dahlias, we should choose the soil with fine soil, no pollution, rich nutrients and no diseases and pests. We can mix ordinary garden soil with plant ash, or garden soil, humus soil and some river sand with uniform thickness. In this way, the prepared soil is rich in nutrition, has certain looseness, has better drainage performance, and the salinity is also appropriate. Note that the salinity of the soil for cultivating dahlias should not be too high. Before using the soil, if possible, the soil can be disinfected with relevant drugs. The seeds of Dahlia should be plump, and the seeds of Dahlia varieties that are easy to bear fruit can be harvested in the autumn of the previous year

Sowing method

We sprinkle the seeds of Dahlia evenly on the soil prepared for flowers, and then spread them evenly on the seeds of Dahlia with moist and fine soil. Then we can cover it with a layer of plastic film, which should have a little gap with the soil, which is conducive to ventilation and moisture preservation. After sowing, the temperature of the planting environment should be kept between 20 ° C and 25 ° C. after about seven days, dahlia seeds will sprout. After that, we should often water to keep the soil moist. Ventilate frequently after sowing, and pay attention to shade when seeds germinate, but remove the plastic film after Dahlia comes out neatly, and move to a sunny place for planting
