How to propagate a Radermachera sinica? An introduction to the common propagation methods

The scientific name of the Radermachera sinica (China doll, serpent tree) is Radermachera sinica. It likes a hot, humid environment with plenty of sunlight, tolerates high temperatures, fears cold, prefers moisture, and dislikes dryness. For cultivation, use loose, fertile loam and sandy loam that drains well and is rich in organic matter. The flowering period is from May to September, and the fruiting period is from October to December. Now let us take a look at the propagation methods of the Radermachera sinica!

Seed propagation

At the end of December, when the capsules are close to splitting and the seeds are fully mature, harvest the long strip-shaped capsules. After drying them in the shade, shake out the winged seeds, rub them, and winnow away the membranous fragments of the seed wings, then store them dry until sowing in the following spring. They can also be soaked for 2 to 3 hours and then mixed into moist sand, spread thinly in a large plastic basin inside a shed or greenhouse, keeping the seeds and sand moist, checking frequently to prevent mold, and sowing in the ground only after the seeds germinate. For dry-stored seeds, between March and April, first soak them for 3 to 4 hours, remove them and spread them out briefly to dry, then mix them with sandy soil and scatter them on a prepared seedling bed, lightly cover with a thin layer of soil, cover with plastic film to retain moisture, and remove the film once the seeds sprout, then set up a light shade frame for shading. When they grow 2 to 3 true leaves, transplant them with a soil ball at a wider spacing; alternatively, wait until they grow 4 to 5 large leaves, then plant them in pots or bags. With strengthened water and fertilizer management, they can be sold as commercial seedlings in the same year.

Cutting propagation

Between March and April, when the ambient temperature reaches about 15°C, cut 1- to 2-year-old woody branches about 15 cm to 20 cm long, remove all the leaves, and make the lower cut preferably 0.5 cm below a node. Insert them into a sandy loam seedling bed, with the cutting inserted to a depth of about 1/3 to 1/2 of its length. During the period when the lower cut is healing and rooting, spray water to keep the seedling bed moist. Only after they have grown a sound root system should they be transplanted with a soil ball into pots; it is best to plant 2 to 3 together, so they can take shape and be sold sooner.

Layering propagation

Between March and April, on 2-year-old strong branches or stems, just below a node, carry out ring-barking, with the bark removal width generally 2 to 3 times the diameter of the stem being layered. Below the ring-barked wound, tie a piece of 15 cm × 20 cm plastic film. Using clean, moist peat soil or sandy loam, press and shape a soil ball 8 cm to 10 cm in diameter around the ring-barked spot. Then wrap the soil ball well with plastic film, leave an opening at the top for water, and tie it against a thick main trunk to prevent it from drooping and being broken by wind. By late autumn, after the ring-barked wound has grown a fairly sound root system, cut it away from the mother plant and plant it separately in a pot.
