Detailed Guide to Common Herbaceous Flower Cultivation Techniques in Northern Regions (Part 1)

In herbaceous flower cultivation techniques, some varieties have strict temperature requirements, while others are very sensitive to light. Based on several years of production practice experience, the author has summarized the key cultivation techniques for several herbaceous flowers commonly used in northern regions in recent years, for the reference of colleagues.

  Key points for propagation and cultivation: Propagate by sowing or cuttings. For sowing, sow in open ground in early September, and transplant once in late October. Double-petaled varieties can be propagated by cuttings; in autumn, take stem segments about 6 cm long from the stem tips and insert them into sand, where they will soon root. Cold-resistant. Prefers sunny sites, a cool and dry climate, and well-drained, loose and fertile soil. Afraid of waterlogging and averse to heat; growth is poor when there is too much rain. In the Yangtze River basin it can overwinter in open ground, while in the north it needs a greenhouse or cold frame to overwinter. When lifting seedlings, the seedlings should be kept with soil. During cultivation, moisture should be controlled, appropriate pruning should be done, and fertilizer should be applied. After flowering, cut off the flowering branches, apply fertilizer, and water once a day, and it can bloom again by September. For overwintering at the seedling stage, straw should be spread over the roots.
  Horticultural uses: Wallflower has golden-yellow flowers, which is relatively rare among herbaceous flowers. It can be used in flower beds and flower borders, and can also be grown as a potted flower.
