Star flower can be cutted in a year, as long as the surrounding temperature is appropriate, it can survive. But in spring and autumn is a suitable time, autumn can be combined with pruning, which can not only obtain cuttings, but also promote the growth of new branches.
Star flowers need to grow well. Cut appropriate cuttings from above. They need to grow healthily. They have top buds on them. There are 3-5 nodes on the branches. The length doesn't need to be too long. It's about 5-10cm. Then cut off the flowers and bracts at the lower end and the leaves at the lower end. If the upper part of the leaf is longer, it needs to be cut off to reduce water loss and evaporation.
The soil suitable for rooting can be mixed with saprophytic soil, plain sand and perlite, which can not only keep air permeability, but also increase nutrition.
After the preparation work is done, cutting can be carried out. Dip the branch with a little rooting powder, and then insert it into the soil. The surrounding growth environment should be maintained well, with appropriate temperature and humidity. It can take root in a period of time when it is placed in the place of astigmatism.
