A bunch of red sowing time can depend on the time you want it to bloom. If you want it to bloom in May 1st, you should plant it in August of the previous year. If you want it to bloom in November, you can plant it in the early spring of that year.
The sowing time of a bunch of red flowers needs to be adjusted according to the region. If it's in North China, there's no problem sowing at any time of the year. In other areas, it's better to sow in spring.
Before sowing, a small amount of base fertilizer should be applied to the substrate and water should be poured through it. The seeds are then seeded into the soil and then covered with a layer of substrate. A small amount of water, keep humidity, after 8 - 10 days can germinate.
