(2) In the growing period, long branches often germinate in the rhizosphere, and they should be smoothed as soon as they grow, so as to keep the original plant shape of the old plant.
(3) When old plants need to be updated, long branches need to be kept. When the long branches grow to 10 ~ 15 cm, they need to be pulled out, and some old plants need to wait until they grow thick.
(4) Before sprouting in spring every year, the top of branches must be cut off, leaving only the base of 10 ~ 15 cm, and all leaves, other pests and diseases, dead branches and over-dense branches should be removed, so as to promote the new shoots to sprout neatly and robustly.
(5) When the spring shoots grow to 4-5 knots, they need to be plucked. In the future, not only will there be many flowers, but also the plants will be full.
(6) After the flowers wither, cut off the top and leave 3 ~ 5 nodes to promote the growth of new branches and keep the flowers flourishing, otherwise, only a few secondary branches will sprout at the top of the old branches, with few flowers and fine flowers.
