How to propagate hibiscus

1. Seeding method

Its seeds are very hard, so they must be handled before planting. After selecting the fuller seeds, put them in concentrated sulfuric acid, soak for about 5-30 minutes, and then rinse them with clean water. Prepare a clean substrate, disinfect it before planting, sow the seeds, maintain the germination temperature at around 25-35 degrees, and wait for 3-5 days for it to germinate.

2. Grafting

This method of propagation is best done in the spring, but can be done year-round if a greenhouse is available. Prepare the scion and rootstock in advance, and you can use the methods of approach grafting, cleft grafting, and cut grafting. The width of the scion and the rootstock should be the same. The lower end should be cut into a wedge shape, the top should be trimmed off with a knife, split from the middle, and then the wedge-shaped cuttings should be inserted. Finally, tie it up with a plastic bag and place it in a semi-shaded place indoors.

3. Cutting method

The best time to use the cutting propagation method is around May and June. If you want to do it in winter, you have to choose a greenhouse. Cut a 10-12cm branch from the mother plant in good growth condition, remove all the leaves at the bottom, and only keep 1-2 leaves on the top. Prepare clean cutting soil in advance, insert the processed branches into it, spray some water every day, and wait for rooting.
