How to raise zinnia

Zinnia, also known as Zinnia and Bubugao, is an annual herbaceous flower of Compositae, with a plant height of 50-90 cm and a flowering period of 6- 10 month.

I like sunny days, but I can also tolerate semi-cloudy and drought. I don't have strict requirements on soil, but I want to grow well in fertile and well-drained soil.

Breeding with seeds, usually sown in greenhouse in late March, germinated above 65438 00℃ for about 5 days. Because there are few lateral roots of zinnia, the seedlings are slow to be transplanted, so it is forbidden to transplant large seedlings, usually when there are 2 ~ 3 real leaves. In order to make the plant short and strong, you can pick the core when the plant height is 10 cm, keep two pairs of true leaves, and bloom about 2 months after sowing. Choose plants with vigorous growth and good color when collecting seeds. After the petals are dried, they should be harvested together with the stems, hung in a ventilated place indoors, and harvested after maturity.

Zinnia grows vigorously, but it grows poorly in the later period. In this regard, we can cut off the residual flowers in time and strengthen the management and maintenance of fertilizer and water; It can also be sown in summer, with autumn flowers 1 ~ 2 coring. If it is a zinnia for cutting flowers, you can't pick the heart. The flowers at the top of the main stem are better.

Zinnia has strong adaptability and long flowering period. It is mostly used in flower beds and flower borders in gardens, and can also be used as cut flowers.
