Any of various perennial herbs of the genus Swift. Because of its unique flower shape, it is very similar to a swallow. Originated in southern Europe, it is cultivated in all provinces of China and is deeply loved by people. So do you know what are the methods of planting delphinium seeds? What is the medicinal value? How long is the florescence? According to Uncle Wang, a farmer who grows delphinium, the florescence of delphinium is generally about 20 days, and the flowering of delphinium is about between August and September every year.

First, the seed planting method of delphinia

There are many seeds in the fruit, and the seeds are small, which are collected and dried and stored in a cool and dry place in the room. In order to make delphinium multiseason blossom can be sown by stages, but the southern cultivation should stagger the flowering period in midsummer and hot days.

The perennial delphinium of the same species can also be propagated by cutting and ramet. The cuttings of delphinium are raised in spring and picked and planted in wet sand beds or sand tables. Ramet can be carried out in spring and autumn, the seedlings germinated around the old plant, dug up with roots, divided into small plants, if the spring ramet can blossom in the same year.

Delphinium must keep the soil moist after sowing. The easiest way is to cover some grass and gradually remove the mulch after emergence.

To water swallow grass to master between dry and wet, flowering should be appropriate more watering, do not make the soil too dry.

5. Fertilization

The soil is kept moist during the flowering period, which can prolong the flowering period. According to the growth status of delphinium, cake fertilizer and water are applied 1-3 times a month.

6. Height control

After changing the basin, paclobutrazol can be used to control the height of the plant. The specific method is to apply 0.5% paclobutrazol every 2 weeks.

7. Seed collection

The seeds of swallow grass mature from August to September, because the seeds mature first if they blossom first, and the fruit will crack naturally after ripening, so they should be harvested in time so as not to scatter.

When the disease occurs, the diseased plant is cleared in time, burned centrally, and sprayed with 50% methyl topiramate wettable powder diluted 500 times. The common pests of swallows are aphids and nocturnal moths, which are sprayed with 2000 times diluted 10% deworming EC.
