The breeding methods of Gardenia jasminoides are sorted out in the planting net, which are listed below for netizens' reference. Method 1. Cuttage is propagated in greenhouse from October to November in the north, and can be cut at any time from April to the Beginning of Autumn in the south, but the survival rate is the highest between summer and autumn. Cuttings select healthy 2-year-old branches with a length of 10-12 cm, cut off the lower leaves, first dip them in vitamin B12 injection, and then insert them in the sand. They can take root in about 15 days at 80% relative humidity and 20: 24 ℃. It is better to soak in indole butyric acid of-6 power of 20-10 to-6 power of 50-10 for 24 hours. When the rooting seedlings begin to grow, they can be transplanted or put on the pot for a single plant, and can blossom after 2 years. Method 2. Striping propagation in April, robust branches were selected from 3-year-old mother plants, which were 25cm long and 30cm long. If there were trigeminal branches, three seedlings could be obtained at the fork at one time. Generally, it can take root after 20-30 days, can be separated from the mother plant in June, and can be planted separately or single plant in the next spring. Method 3. Sowing and propagation are mostly carried out in spring, and the seeds germinate slowly, germinate about 1 year after sowing, blossom after 3-4 years, and it is not easy to receive seeds in pot plants in the north. Gardenia propagation points for attention: cutting, in the plum rain season with twigs 15 cm long, cut in the seedbed, 10-12 days to take root. In April, biennial branches were selected, 20-25 cm long, buried in the soil, kept moist, rooting for about 30 days, separated from the mother plant in summer, and planted in the following spring. Transplant seedlings or potted plants, spring is better, in the plum rain season, need to bring soil balls. Keep the soil moist during the growing period, and water more during flowering and midsummer. Fertilize once a month and increase phosphorus and potassium fertilizer before flowering. Pruning and shaping in the early spring of the following year, and cut off dead branches and long branches in time.
