Reasonable close planting: generally planted in late February to early April, the first soil preparation for bed, each planting about 2 rows, plant spacing of about 7-12cm. Water and fertilizer: base fertilizer should be fully applied, compound fertilizer should be applied every half a month after germination, drainage should be paid attention to in the rainy season, and proper watering should be required if the soil is dry.

First, choose high-quality seed balls

2. In order to prevent the overgrowth of plants, the shading net should be removed in time during the peak period of plant growth, otherwise it is easy to affect the quality of flowers.
