Key Techniques and Methods for Cultivating Indian Lobelia (Lobelia chinensis)
Indian LobeliaIt prefers a moist environment, tolerates light moisture and drought to some extent, and is cold-hardy, able to overwinter naturally in the field. It grows wild in moist places such as field ridges, grasslands, ditch edges and stream banks. For artificial cultivation, moist spots along ditch edges and riverbanks are best, and sandy soil is preferable.
Methods include seed propagation, cutting propagation and division propagation. In production, division propagation is mainly used; to expand propagation, cutting propagation can also be used.
Division propagation
In spring between April and May, after new shoots emerge, each clump can be divided into 4-6 plants depending on clump size. Then dig furrows and plant at a row spacing of 15-25 cm and a plant spacing of 6-10 cm.
Cutting propagation
The hot, humid season is the suitable period for cuttings. Cut stems and branches from the plants and insert them into the soil. At a temperature of 24-30°C and with the soil kept moist, they will root in about ten days. Transplant them to the field the following spring. For field management, keep seedlings at a height of about 6 cm.
Field management
During the seedling stage, pay attention to loosening the soil and removing weeds. Apply farmyard manure once after planting; after the summer harvest, topdress once with livestock manure or ammonium sulfate, urea, etc.; in winter, apply decomposed manure or compost. In dry seasons, irrigate to keep the soil moist at all times to promote growth.
