Pour next mature fruit, dry in indoor shade for 1 day to 2 days, take off the seeds of the red skin, a little pile retting after using fine sand or put in water rub the red skin dry in the shade, die in the sun, can not lose water, appropriate namely pick namely sow or mix wet sand storage to the next year February to March sowing, germination rate 70% to 80%. Saucer Magnolia is a hybrid with unstable offspring that cannot maintain all the habits of a good variety. Therefore, it is rarely used in the breeding of good varieties but is often used in the breeding of new varieties.

Cutting propagation

Saucer Magnolia is cut from May to July when growth is at its peak. The choice sapling is born in that year branch makes cutout, the upper part stays a few leaves, immerse branch lower part 50 mg/l indole acetic acid, root powder or nafthene acetic acid after 6 hours, insert wet sand or vermiculite bed inside, proper shade, and often spray protect moisture, the survival rate can reach 70% or so.

Grafting propagation

Usually, Saucer magnolia parents such as purple magnolia or magnolia, this species or yellow orchid, white orchid and other genus plants are used as rootstocks, which can be split grafted, bud grafted, cut grafted, belly grafted and other ways, but the survival rate of split grafted and bud grafted is higher.

Layering propagation

Choose well-growing plants, take 1 to 2-year-old branches of 0.5 to 1.0 cm thick for layering, if there are branches, can be pressed on the branches. Layering time in February to March is better after the pressure can take root in the same year. Saucer magnolia can Flower in 2 to 3 years after transplanting.

Tissue culture propagation

Saucer Magnolia can maintain its excellent characteristics in tissue culture. The terminal buds and lateral buds are generally used as explants. The medium for primary and secondary culture is MS+3.0mg/L6-BA+0.2mg/L LIBA, and the medium for root induction is 1/2MS+0.5mg/LNAA.

Disease & pest control in Saucer Magnolia

Pest control


If aphid is found to be harmful to buds and buds, it can be killed by quick killing or by 500 times of washing powder, and then sprayed with clean water to wash the branches and leaves.

Insect pest shell
