What is the time and method of osmanthus grafting?

Osmanthus is generally grafted in the spring during the growing season. It is best to take early spring when the sprouts are about to germinate, that is, in March and April every year. Grafting can be carried out between April and June in the northern region, and in February in the southern region.

Of course, grafting can also be carried out in late spring and early autumn, but the survival rate will be lower than that in early spring. Therefore, if the general experience and technology are not enough, it is best to choose the grafting of osmanthus before and after the Qingming Festival.

Different varieties of osmanthus can be grafted, and large-leaved privet trees, small-leaved privet (holly), small ash trees, wax trees, ash trees, tassel trees (oil boys, cow tendons) and so on. In fact, grafting is a kind of asexual reproduction, grafting the branches or buds of one plant to the stem or root of another plant, so that the two parts that are joined together can grow into a complete plant.

If it is in the north, it is most appropriate to choose the grafting time after April, because the temperature in the north is low throughout the year, and premature grafting may lead to a low survival rate of grafted osmanthus due to temperature discomfort.

Of course, if you are in the south, the time is relatively free, the temperature is generally high, the climatic conditions are relatively humid, and grafting can be carried out in autumn or early spring in February every year. However, grafting in autumn is a great test of the level of the grafter, and if there is no high grafting ability, do not choose this time.

In addition to winter, osmanthus grafting can be carried out in spring, summer and autumn. Cut joints are adopted in the spring. In summer, the grafting method is used. In autumn, a "T" shape is used for budding.

The grafting time of osmanthus is generally in spring, and it is best to carry out it before osmanthus germination. The grafting method is as follows:

1. Grafting and propagation.

The rootstock can be used ligustrum, ligustrum, ash and tassels, etc. When propagating in large quantities, ligustrum microphylla is mostly used in the north. Before germination in spring, cut the rootstock from 5 cm above the ground, cut the 1 to 2 year old thick branches of osmanthus 10 to 12 cm long, and cut the two sides of the base into a 45-degree slope.

Make a longitudinal cut about one-third of the side of the rootstock, 2 to 3 cm deep. Insert the scion into the incision, align the cambium, tie it tightly with a plastic bag, and bury it in the soil. The grafting of ligustrum ligustrum as rootstock has a high survival rate and fast growth, but it is easy to form the phenomenon of "small feet".

2. Relying on the connection method.

Potted osmanthus is mostly used by the grafting method, and the tassel is used as the rootstock. Grafting should be carried out in the growing season, and scion and rootstock with similar branch thickness should be selected, and prismatic incisions should be made at the appropriate part of the scion, reaching deep into the xylem. Make a cut in the rootstock that is the same size as the scion, put the two joints together, the cambium is tightly connected, and tie it tightly with plastic strips.

After healing, cut the rootstock on the interface and the scion underneath.

In spring, when osmanthus flowers are just budding, it is about late March to early April.

I think grafting in June is better. Because the temperature in June is already very high, osmanthus has also begun to develop, and it is better to graft at this time.

The best time for osmanthus grafting is in the spring of each year, which is also from March to June, and the grafting time in different regions will be appropriately delayed or advanced.

Grafted rootstocks are mostly made of privet, ligustrum, small wax, water wax, white ash and tassels (also known as oil boys, cow tendons) and other rootstocks. When propagating seedlings in large quantities, ligustrum microphylla is mostly used in the north.

Before germination in spring, cut the rootstock from 5 cm above the ground; Cut the 1 2-year-old thick branches of osmanthus 10 12 cm long, cut the base side into a long 2 3 cm sliced surface, and the opposite side cut into a small bevel of 45 degrees; make a longitudinal cut about 1 3 on one side of the rootstock, about 2 3 cm deep; The scion is inserted into the incision to align the cambium, tied tightly with a plastic bag, and then buried in the soil for culture.

The survival rate of ligustrum ligustrum as rootstock will be relatively high, the grafted seedlings will grow fast, the life span is short, and it is easy to form the "small foot" phenomenon of "thick at the top and fine at the bottom". It is a rootstock with water wax, which grows slowly but has a long lifespan.

Osmanthus grafted post-grafting

Osmanthus grafting within 7-15 days to insist on observing whether the grafted seedlings survive, if they die, they can be supplemented in time, if the grafting survives, they can grow branches and leaves normally after 2 months, and they usually stay in the appropriate amount of fertilization, watering and shade. Wait until the next spring to germinate and remove the wrappings and manage them normally.

July is the best time to graft osmanthus with tassels.

Tassel is a deciduous shrub or small tree with a flowering period of 4 to 6 months and a fruit ripening period of 9 to 10 months. The requirements for soil are not strict, and neutral, slightly acidic, and slightly alkaline can be adapted. Grafting osmanthus with tassels has a strong affinity and good growth.

Osmanthus bonsai cultivated with tassel stumps can be kept at home. The grafting time is generally better when the panicle germinates.

There are many methods of osmanthus grafting, among which the grafting method is a commonly used one, and the potted osmanthus is mostly used in China.

Its advantages are: suitable for grafting for a long time, easy to survive, fast forming, early flowering.

Under natural conditions, it can be grafted during the growth period and in the greenhouse in all seasons.

Osmanthus by the technical points:

1. Cultivate rootstocks.

The rootstock tree species used for grafting osmanthus include privet, tassel tree, etc.

The rootstock for grafting should be robust, free of pests and diseases, and the thickness of more than 1 cm should be 2-3 year old seedlings or 2-3 year old branches on perennial trees.

2. Choose a scion.

There are varieties of osmanthus such as golden osmanthus, silver osmanthus, red osmanthus, and four seasons osmanthus.

First of all, the osmanthus varieties can be selected according to the preferences and resource conditions, and then the 2-3 year old branches with robust growth, full development, no disease and insect damage, and moderate size are selected from the selected osmanthus trees as scion.

At the beginning of spring, fertilization begins in the evening when the temperature rises above 15, when the shoots begin to grow and fertilizer is needed.

If you are using compound fertilizer, the amount of each application is 4 grams (about a cap of a small mineral water bottle), make four small holes around the potting soil or plant, put the compound fertilizer evenly, and then cover it with soil (change the position when punching the hole next time), fertilize once every 10-15 days, until the temperature drops below 8 in the autumn evening.

If you apply organic fertilizers such as cake fertilizer, the dosage is 1 3 bowls of the eating bowl (without mixing with water).

If you buy a packaged flower fertilizer from a florist, just follow the packaging instructions, if there are no packaging instructions, you should ask clearly.

When you see a flower bud growing, you should stop fertilizing, and the excess nutrients will drop the buds (except for the four seasons of cinnamon).

If quality is pursued, apply organic fertilizer.

If speed is pursued, spray and apply inorganic fertilizer at the same time as organic fertilizer.
