Propagation methods of Rhododendron in various ways

Seeing the brilliance of azaleas affects the hearts of many friends who plant azaleas. So, is it easy to reproduce azaleas? What are the breeding methods of rhododendron? There are also many ways to reproduce azaleas. This paper intends to choose the common methods to make a brief introduction. For reference.

Rhododendron can be propagated by five methods: cutting, grafting, striping, splitting and sowing, among which the method of cutting is the most common. The breeding quantity is the largest, and the seedling formation is the fastest; the grafting propagation is the most complex, and only the varieties that are not easy to survive are used for grafting; sowing is mainly used to cultivate varieties.

1. Insertion method

This method is the most widely used and has the advantages of simple operation, high survival rate, rapid growth and stable characters.

① time: West cuckoo in late May to early June, rhododendron in the first and middle of June, spring cuckoo and summer cuckoo in mid-late June, when the branches are moderately old and tender, and the climate is warm and humid.

② cuttings: take the current year's rigid woody branches, break off with heel, trim the hairy head, cut off the lower leaves, keep the top 3 to 5 leaves, moisturize and wait for insertion.

③ insertion management: orchid soil, alpine humus soil, yellow soil, vermiculite and so on can be used in the substrates. The suitable depth of cuttings is 1x3 to 1max 2 of ear length. Spray water after insertion, cover with film moisturizing, give proper shade, keep the substrate moist all the time within a month. Cuckoos, spring cuckoos and summer cuckoos can take root in about a month, while rhododendrons take about 60 to 70 days.

2. Grafting

It can connect multiple ears with one rootstock, multiple varieties, fast growth, good plant shape and high survival rate.

① time: from May to June, the tender shoots were split or ventrally grafted.

② rootstock: choose 2-year-old rhododendron, require proper thickness of new shoot and scion, rootstock varieties are cuckoo "jade butterfly" and "purple butterfly".

③ scion: on the mother plant of rhododendron, cut the tender shoots 3 to 4 meters long, remove the lower leaves, retain 3 to 4 leaflets at the end, cut the base into a wedge with a blade, and the cutting surface is about 0.5 to 1.0 meters long. 5Graft management, cut off the leaves at 2 to 3 meters of the new shoots of rhododendron in the same year, cut 1 meters longitudinally, insert the wedge end of the scion, align the cortex, bind the joint with plastic film tape, and tie the mouth of the plastic bag to moisturize; put it under the shade shed, avoid direct sunlight and exposure. Seven days after grafting, as long as there are small drops of water in the bag and the scion does not wilt, it is possible to survive; remove the bag in 2 months and remove the binding band in the next spring.

If you want to grow azaleas but don't want to buy them back in the flower market, try the above two most commonly used breeding methods. However, attention should be paid to the requirements of time and reproduction.
