Method and steps of planting black heart chrysanthemum seeds

1. Germination

In order to ensure the germination rate of blackheart chrysanthemum, you must use new seeds of the year, select seeds with full grains, wash them in clean water, soak them for 4 hours, take them out and put them in a cool place to dry. This will allow the seeds to have a certain amount of moisture, which is very helpful for them to take root and germinate.

2. Land preparation and soil preparation

Generally, ground-planted blackheart chrysanthemums should be planted in places with higher terrain, good ventilation and sunshine, and where the soil layer is relatively deep. The soil should be renovated in advance and sufficient base fertilizer should be applied to accelerate the growth of the plant. If it is potted, you have to prepare the potting soil yourself. You can use leaf mold and river sand, which not only has certain nutrients but also has good drainage.

3. Sowing and seedling raising

Sprinkle the seeds of blackheart daisy on the surface of the soil, then cover it with a layer of fine soil and water it thoroughly, waiting for the seeds to take root and sprout. The plant should be placed in an environment with scattered light and the soil should be kept moist. After the seedlings grow out, the light can be increased, but it should not be exposed to direct sunlight. In addition, fertilizer should be added after it grows a little bigger.
