When the height of goldfish grass seedling is about 9 cm and there are 8-10 true leaves, the heart should be removed. Leave 4-6 true leaves when picking the heart, take off the tender head with 4 true leaves on the top, and then it can be used as cuttings for propagation.
Two parts of sandy loam and one part of plant ash can be used to select cutting medium, which can be fully mixed and then sifted by fine screen. Wash the nursery box or shallow basin with water, then add 2 /3 of the coarse soil screened out, and then spread about 2cm of fine soil on it, and spray water properly.
When cutting, first take the bamboo stick to drill holes in the substrate, insert the cuttings while drilling holes, and gently compact the culture soil at the base of the cuttings with fingers. The cutting density is about 2.5cmx3cm, and it is better that the leaves of cuttings meet but do not overlap. Spray enough water and place it in a cool place for maintenance.
After cutting, spray water to basin soil and cuttings twice in the morning and evening every day to keep basin soil moist. In cloudy days, there is generally no need to water. If the basin soil turns white, water it appropriately. At the temperature of 15-20 ℃, roots can be produced in ten days or so. After rooting, transplanting can be carried out after the seedlings resume growth.
In the growing period, goldfish grass often produces lateral buds, at this time, as long as the temperature is suitable, cutting can be generally carried out. The shoots with 3 cm long and 4 leaves can survive by cutting. The tender head of the first heart plucking, after cutting, if it is cultivated as a sole plant, its flowering period is basically close to that of the mother plant.
