Does osmanthus trees need to be grafted to bloom, and when is osmanthus grafted?

Osmanthus tree. It can generally bloom without grafting, and grafting is just to get a better shape of the tree and to bloom earlier. Because it generally takes about ten years for the osmanthus that is not grafted to wait for it to be cultivated and formed to flower, the time is still too long.

Therefore, grafting is needed to shorten its forming time, help it bloom early, help it better create a beautiful shape, and let people appreciate it.

Cultivation methods and precautions of osmanthus trees.

First, the breeding method:

1. Soil: as a potted plant.

The requirements for soil will be relatively high, so we need to choose fertile soil and good drainage soil for planting osmanthus trees. It can also be mixed with sand, cake fertilizer, garden soil, and humus soil in the ratio of 3:2 to 3:2. Such soil is not only fertile, but also has good drainage properties.

2. Light: If the osmanthus tree is in the early stage of flowering, then it needs to provide enough sunlight, which is conducive to its flowering. In normal times, it can be placed directly in an all-light environment. However, in summer, it is necessary to carry out shading measures to avoid sunburn of the osmanthus tree.

3. Watering: No matter what kind of plant it is, too much water in the root part will directly lead to root rot. Therefore, we should not water the osmanthus tree too often, it is best to water the potting soil as the watering standard, and the next watering is after the potting soil is dry.

4. Fertilization: Fertilize according to the growth state of the osmanthus tree, and apply some potassium dihydrogen phosphate fertilizer before and after flowering. During the growing season, some liquid fertilizer can be applied, preferably once half a month.

2. Precautions:

1. In order to facilitate the growth of the osmanthus tree and improve the overall beauty of the osmanthus tree, we need to prune the branches and bouquets that have fallen and withered. When the branches are too vigorous and affect the ventilation of the branches of the osmanthus tree, we should also build branches that are too dense to reduce the chance of infection with germs.

2. In the too cold season, we need to take insulation measures for the osmanthus tree. Similarly, if the temperature is too high, cooling measures are also required.

Osmanthus flowers bloom without grafting. And generally osmanthus trees are not grafted, and they are grafted only when there are special needs, such as when there are multiple varieties of osmanthus on a osmanthus tree, or when you want to make ordinary varieties of excellent varieties.

Osmanthus trees are a good tree species for greening, and are often planted in streets, parks, and courtyards. And the general planting is mostly grafted by the method of grafting, thatWhat tree can be grafted with osmanthus? When is grafting? How to graft?

1. What kind of tree can be grafted with osmanthus?

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. And the higher the affinity of grafting, the higher the survival rate, so if you want to graft osmanthus trees, you can find trees with high affinity.

2. When will osmanthus be grafted?

1.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.

2.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.

3. How to graft osmanthus?

1.Preparation

First of all, prepare the rootstock and cuttings required for grafting, and you can choose from the trees described above for the rootstock. Then choose completely lignified branches on the robust, disease-free, well-growing osmanthus tree, remove the excess leaves, and only keep about 3 leaves. Then cut the bottom of the branch at 45° on both sides, with a length of 2-3 cm, to form a wedge shape.

2.Grafting

1) Osmanthus belly grafting: that is, the rootstock is trimmed before grafting. Cut off all at 6-7 cm from the soil surface, and cut obliquely near the rhizome to avoid hurting the marrow. The scion uses 2-3 branches (without leaves), about 10 cm long, and it is advisable to have 2-3 nodes.

The spike joints are then cut into unequal wedges and inserted into the cutting notches of the rootstock to make them closely jointed. Tie the soil with plastic or hemp skin until the top of the scion.

(2) Docking: Then cut the spike joint into an unequal wedge, and insert it into the rootstock cutting hole to make it closely jointed. Tie it with plastic or hemp skin and then press the soil to the joint.

up to the top of the spike. When choosing a mating method, it is best to do so during the growing season and to avoid continuous rainy days.

3.Field management

After the grafted osmanthus seedlings survive, the new shoots grow to about 15 cm and the remaining rootstock branches and tillers should be cut off. From June to August, it is necessary to carry out drought-resistant, fertilization, and weeding work, but the amount of fertilization and watering at the beginning must be controlled, and too much application should not cause the situation of burning seedlings.

In fact, the grafting of osmanthus is not very difficult, generally speaking, it can be carried out according to the above steps. Of course, if you have no experience at all, it is recommended to buy ready-made grafted seedlings directly in the market, which saves a lot of trouble.

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.

Different varieties of osmanthus trees have a slightly different flowering time. As the saying goes: osmanthus blooms everywhere in August. And this August refers to the eighth equinox of the lunar calendar, which is in the Gregorian calendar.

In September and October. In life, the August laurel we often talk about actually refers to the osmanthus that blooms in the eighth month of the lunar calendar, which can be subdivided into golden cinnamon, silver osmanthus and red osmanthus. There is also a type of flowering that blooms throughout the year, and that is the four seasons of cinnamon.

If the cutting section is propagated by cuttings, then if it is an osmanthus branch cuttings that have already bloomed, it will take about four years to bloom. It is the way of grafting, there are a few will bloom in the same year, like the four seasons of cinnamon grafting, if properly maintained, it is not impossible to bloom in the same year. For example, golden cinnamon, silver cinnamon, and red cinnamon are a few that bloom the following year, and most of them bloom in the third year.

But only if the branches are cut off from the osmanthus trees that have already bloomed.

Osmanthus can bloom without grafting.

Grafting is to obtain a better tree shape without changing the characteristics of osmanthus and to bloom early. If it is not grafted, seedlings can be raised by cuttings and sowing. The amount of pruning is large, but the flowering is early; The seedlings are planted and the tree is in good shape, but it is not flowering until about 10 years after planting.

Osmanthus is blooming in all seasons and fragrant in all seasons. It is fragrant in summer and autumn, and slightly fragrant in spring and winter. It is often planted in gardens, on both sides of roads, lawns and courtyards, and is a greening tree species for organs, schools, military, enterprises and institutions, streets and families.

Osmanthus is an evergreen tree with a well-developed root system and opposite leaves. Prefers warm and humid climates and is not tolerant of severe cold.

Osmanthus flowers bloom without grafting. And generally osmanthus trees are not grafted, and they are grafted only when there are special needs, such as when you want to have more than one osmanthus on a osmanthus tree, or when you want to make ordinary varieties cultivated into excellent varieties.

Its grafting is usually carried out in early spring, and the temperature in the later stage is more conducive to healing and recovery, and the success of grafting can be determined in the same year. However, there are also some masters who graft in the fall, and the survival rate is also very high.

1. Cutting method: select annual new branches from the tree that has bloomed, cut them into scion two or three centimeters long and a pair of new shoots, remove the top appearance, and cut the lower end into a wedge. Then the rootstock is processed, the privet is cut off four or five centimeters from the ground, and a knife is cut from the cambium layer and the wooden part, after which the scion can be inserted and wrapped tightly in a plastic bag, and it will heal in about a month.

2. Insertion method: The insertion method should be carried out in autumn, and the selection and treatment method of scion is the same as that of the cutting method, and the side without buds is cut into a straight side. After that, cut diagonally on the side of the rootstock and embed the shaved scion.

After completion, it should also be wrapped in a plastic bag, and it should be kept warm in the later stage to avoid frostbite.

Grafted osmanthus trees are usually made of privet as rootstocks, which can be grafted with silver osmanthus, golden osmanthus and other varieties, but it should be noted that the tree is easy to break from the grafted place when it grows up, so it should be treated with a different head. This means that after the later stage of survival, the grafted part should be allowed to regrow its roots and the rootstock at the bottom should be replaced.

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.
