1. Timely planting. It can be planted every year from February to June in spring and September to December in autumn. Before planting, dig holes with a distance of 1 meter between plants and 1.5 meters between rows. The depth of the hole is 30-50 cm and the diameter is 30 cm. Spread a layer of base fertilizer in the hole and then cover it with a layer of fine soil. Plant one plant in each hole. After covering with soil, tighten it properly and water. permeable.

2. Regular top dressing. Every year in early spring and early winter, combined with soil loosening and weeding, a circular trench is opened around the flower mounds. 5 kilograms of soil fertilizer and 125 grams of compound fertilizer are applied to each mound, and then the soil is covered. In August, apply nitrogen fertilizer again, using 15 kilograms of urea per 1/15 hectare, spread it into shallow ditches next to the plants, and cover with soil. When there are many weeds in summer, pay attention to weed removal.

Maintenance:

1. Pruning. When pruning in winter, select 4-5 strong branches on the main trunk as main branches, and prune the rest as flower branches. Pay attention to cutting off overly dense branches, old, thin, diseased branches, and branches to make the branches evenly distributed. During the vigorous growth period in summer, pay attention to topping or pruning to control the growth and promote flowers.

2. Harvesting. It should be harvested at the right time when it blooms. The method is to pick from the outside first, then the inside, and from the bottom up before the flower buds open. After harvesting, they should be processed and dried in time. The picked flowers should be spread thinly on grass, bamboo mats or plastic films to dry. Be careful not to turn them over to prevent them from changing color and turning black. If the conditions are good, you can also use a new dryer for better results. After drying or tumble drying.
