How to plant black heart chrysanthemum seeds

Sowing time of black chrysanthemum

If we want to propagate blackheart chrysanthemum by sowing, we usually choose spring and autumn.

The best time to sow Rudbeckia is March in spring and September in autumn. Choosing these two times is conducive to the natural growth of Rudbeckia. If we sow in March, it will bloom around June of the same year. If we sow in September, it will bloom around June of the following year after a natural wintering. These two times are chosen because the temperature in these two months is roughly between 21° and 30°, which is suitable for the germination of Rudbeckia seeds.

How to sow black chrysanthemum

In autumn, we can harvest the seeds of Rudbeckia radiata from its inflorescences.

After choosing the right season, we also need to prepare the soil for sowing black heart chrysanthemum. It is best to choose soil with good drainage, rich in humus and nutrients, which is conducive to the germination of black heart chrysanthemum seeds. After we are ready, we can start sowing. Spread the seeds of black heart chrysanthemum evenly on the soil, cover it with a thin layer of soil, then water it enough and provide appropriate sunlight. After that, we need to wait about fifteen days, and the seeds of black heart chrysanthemum will break through the soil and germinate.
