Seedlings can be grown in about a week during the growing season and new tubers can be produced in about 20 days, and not only are tubers such bulbs but seeds and rhizomes can also germinate to produce new plants and tubers when conditions are right. If the above-ground portion is shoveled from the soil, it grows at an average rate of 2 centimeters per day for 5 days, catching up to the height of the unshoveled plant in 15 days. Seeds, rhizomes, tubers and bulbs will only germinate in the current year in a soil layer of 0-10 cm. Seeds below 10 cm can survive in the soil for more than 5 years. Due to the fact that balsam is relatively special, it is currently ranked among the world's top ten malignant weeds. It has attracted great attention from experts at home and abroad.
