Choice of scion and sand bed from robust, pest-free, more than 2 years old hybrid jacaranda, cut the year pumping, stout, bud full, nutrient-rich central branches for the scion. Branches and tips are not appropriate. Cutting time for the hibernation from the end of January to early February, cut the long branches cut into 50 cm long, bundled into small bundles.

River sand to maintain a certain humidity, so as to avoid shrinking branches. If the branches buried in the outdoor, use wooden overhead, covered with plastic film, and then covered with straw, rain and wet.
