Echinacea is a long sunshine plant, which needs 14-16 hours of light and 7-8 weeks of high-intensity light in the flowering stage. In the northern region, it usually blooms in the late May, and the flowering period lasts until September.
During the growth period of Echinacea, the temperature should be kept at 16 ℃ - 24 ℃ in the daytime and 10 ℃ - 16 ℃ in the evening.
The application amount of water-soluble fertilizer is 50-75rrg /kg from the appearance of radicle to the development of cotyledon, 100-150mg /kg from the development of cotyledon to the growth of four real leaves, and 250mg /kg after planting. Each cycle can be applied once or twice a week.
Echinacea is strong and resistant to drought. Therefore, watering should follow the principle of "see the dry and see the wet". When the basin soil is dry, water it again, once.
Echinacea is not strict to the soil, but it grows best in the deep and rich humus soil.
0.05% magnesium sulfate should be supplemented 1-2 times to prevent magnesium deficiency in plants.
Supplement 1-2 times of chelated iron to prevent iron deficiency.
It is suggested that long-term slow-release fertilizer should be added to potted soil.
In November, the temperature in the northern region is low, so it is necessary to move the Echinacea into the room for maintenance. If the room temperature is above 0 ℃, Echinacea can grow healthily.
Place the Echinacea in a ventilated place to keep the air flowing.
