Generally, when the seedlings grow to about 10 cm, they can be transplanted.
Before the transplanting of Echinacea, we need to prepare and apply fertilizer to the plot, 2500-3000 kg of rotted chicken manure, cow manure and ring manure per mu.
Before transplanting, the seedlings should be sterilized to reduce and avoid the spread of pathogens after transplanting. Usually on the day before transplanting, spray 600 times of 75% chlorothalonil wettable powder once, and the next day the seedlings can be raised.
The basin soil needs to use loose and fertile mixed soil and culture soil.
In order to improve the survival rate after transplanting, the seedlings should be dug out together with roots and soil to minimize the damage of roots.
When planting, choose the number of plants according to the size of the flowerpot. Generally, 3-5 trees are better.
Dig a small pit with a shovel in the basin, put the seedlings into it and then straighten it, then fill it with the surrounding soil, compact the soil with your hands, and then water it once to ensure the survival of the seedlings.
After transplanting, the pinecones need to be plucked once in the early growth stage to promote branching.
Don't water too much. Master the principle of "wet when dry". Water once every 10 days or so. When the air humidity is high in the plum rain season, control the watering even more.
The growth of Echinacea after transplanting is fast, so nitrogen fertilizer should be supplemented in time. Generally, the first topdressing is carried out 20 days after transplanting, and diluted liquid fertilizer is used to promote growth. Fertilize once a week when the flower bud is formed, and sprinkle water after each fertilizing to avoid the fertilizer sticking to the plant.
The cultivation is generally carried out in the greenhouse and placed in the sunny place with good ventilation. The minimum temperature shall not be lower than 10 ℃, and proper shade is required in summer.
