How to Propagate Rhododendron
The editor will answer for you how to propagate rhododendron and the knowledge of green plant flowers about rhododendron propagation methods and precautions. Next, the editor will introduce to everyone.
There are many methods to propagate rhododendrons, among which cutting propagation is the most common and yields the largest amount. For rhododendron cutting propagation, new shoots should be selected as cuttings, and they can take root in about a month; layering propagation is the fastest to grow seedlings, by cutting the healthy branches to form a ring of bark and then sprouting roots; grafting propagation can be used for varieties that are difficult to root through cutting. Let's talk about it in detail below.
I. Cutting Propagation
Cutting propagation is relatively common, with a large amount of propagation and a high survival rate. As long as the climate is suitable, cuttings can be made in any season, but early summer is the most suitable. Generally, we take new shoots as cuttings, trim the top flat, clean the lower leaves, and leave 3-5 leaves on the top. The soil can be mixed with humus soil, yellow heart soil, and vermiculite. The depth of cutting is about half of the cutting. After cutting, keep the soil moist, place it in a shaded place for maintenance, and it can take root in about a month.
II. Layering Propagation
Layering propagation has a higher survival rate from the end of October to the beginning of February, and seedlings grow the fastest. Generally, two-year-old healthy branches are taken from the mother plant of the rhododendron, starting to scar about 10 centimeters from the top, that is, using a knife to separate a ring of bark about 1 centimeter wide, cutting off the downward transport path of organic matter to gather in one place and sprout roots and buds. Fill it into slightly moist soil and place it in a place where it is not exposed to direct sunlight for management.
III. Grafting Propagation
For varieties that are difficult to root through cutting, grafting propagation can be chosen, which grows faster and has a good survival rate. Select a three-year-old plant as the rootstock, and the thickness of the new shoot and the cutting should be suitable. We create an interface on the rootstock, insert the branch into it, wrap it with plastic film, place it in a shaded place, and generally the wound will heal after two months.
