Last Updated: 2024/11/22, The propagation methods of rhododendron can be divided into five methods: cutting, grafting, striping, splitting and sowing, among which cutting is the most common and the reproduction quantity is the largest. Striping is the fastest to form seedlings, and grafting is the most complex. Only varieties that are not easy to survive by cutting are grafted and sown.

Rhododendron propagation methods can be used cuttage, grafting, layering, sub-plant, sowing five methods, of which cuttage method is the most common, the largest amount of reproduction. Grafting propagation is the most complex. Grafting is used only for the varieties that are not easy to survive by cutting. Sowing is mainly used to cultivate varieties.

seeding method

Sowing, evergreen azaleas are best picked with sowing, deciduous azaleas can also store seeds until spring sowing the following year. When the temperature is 15~20℃, it will sprout in about 20 days.

cuttage method

Cuttage propagation, cuttage pots to 20 cm diameter of the new shallow tile pots as well, because of its good permeability, easy to root. Culturing soil mixed with 20% humus garden soil, 40% horse manure and 40% river sand can be used as substrate. Cutting time in spring (May) and autumn (October) is the best, when the temperature between 20~25℃, the most suitable cutting. When cutting, select the half-lignified branches of the current year as cuttings, press the knife with extremely sharp pliers; cut 6~10 cm with nodes, cut smoothly and neatly, cut off the lower leaves, leaving only 3~4 leaflets at the top. Buy vitamin B12 injection 1, after opening, the cuttings dipped in the liquid medicine, take out for a while can be cut. Before insertion, the culture soil in the pot should be sprayed with a watering can the day before, but it should not be sprayed too much. The next day, it is just moist, which is most suitable for cuttage. The depth of insertion is 3 - 4 cm. When planting, first save a hole in the soil with chopsticks, then insert the cuttings, compact them with hands, make the pot soil fully contact with the cuttings, and then pour water once. After inserting, the flowerpot had better be covered with a plastic bag, and the bag mouth should be tied with a belt. When watering is needed, open it again, and tie it again after watering. Cuttings of the pot should be placed in the direct sun without sunlight, cuttage pot soil every day within 10 days to spray water, in addition to rainy days, cloudy days can be sprayed once, dry climate should spray twice, but the amount of water should not be too much every day. After 10 days, always keep the soil moist. Shady for 4 to 5 weeks, until after germination can gradually let it accept some sunlight. It usually takes about 2 months to root. After that, it only needs shade for 2~3 hours at noon, and the rest of the time can be allowed to receive light to facilitate its own production of nutrients in photosynthesis.

grafting method

Western cuckoo adopts grafting propagation more often, often split young branches, grafting time is not limited, rootstock is mostly two-year-old cuckoo, survival rate is more than 90%.
