Cultivation methods and precautions of osmanthus tree (teaching you the steps to raise a good osmanthus tree)
The common cultivars of osmanthus are danggui, golden osmanthus, silver osmanthus and four seasons osmanthus, and different varieties of osmanthus bloom at different times, and the color of the flowers they produce is also different. Golden osmanthus blooms from September to October and is often golden yellow in color. Silver laurel blooms from September to October and is white or yellowish white in color. Tan cinnamon blooms in October and is mostly orange-red or orange-yellow in color. Four-season laurel blooms in all seasons, with a small number of flowers every month, the color is white.

1, cuttings: cuttings generally in June-July or September-October, cuttings to sandy loam is appropriate. The cuttings are selected from half-mature branches of the current year, and the top branches are the best. After the cuttings should be timely shade, watering, and strengthen the management of water and fertilizer. General cuttings 20 days after the start of healing, 30-40 days to root. Winter should have measures to prevent cold, the next year the seedlings can grow to about 30 centimeters tall.

2, pressure: pressure is divided into two kinds of high pressure (air pressure) and ground pressure, can be carried out throughout the year, high pressure method in early April, ground pressure method in early April or rainy season is appropriate. Pressing strips should be carved or ring peeling, 1 year after the separation from the mother plant. Ground pressure of the pressure strip into the soil depth of about 4-5 cm, into the soil part of the branch the more curved the better.

3, grafting: grafting reproduction time in March-April. Rootstock mostly with small-leaved privet, big-leaved privet. Grafting method for branching, cutting, splitting, leaning can be. Grafting requires shade and attention to moisturizing. Cutting and splitting requirements interface as low as possible, generally 3 cm from the ground to cut off the rootstock. After tying the soil to the top of the scion, so that it is possible to root from the scion part, to improve the survival rate.

4, sowing: winter or early spring sowing, strip sowing, row spacing 15-20 cm, 30-40 seeds per meter long, 8-10 kg of seed per acre, covered with humus or fire soil, about 1.5 cm thick, and cover grass. Generally 40-50 days after sowing began to germinate, lasted up to 50-60 days, germination is very untidy. July-September for the seedling growth period, pay attention to fertilizer and drought. One year old seedlings can be released from the nursery at a height of more than 30 centimeters.

5, seedlings out of the nursery: pressure seedlings, grafted seedlings rooted, can be in the winter afforestation or planted in the nursery to cultivate large seedlings. Cuttings up to 30 centimeters tall or more, sowing seedlings to reach 25 centimeters or more, ground diameter of 0.4 centimeters or more, can be out of the nursery afforestation or transplanted to the large seedling cultivation area. Seedlings should be kept as intact as possible when starting, and should be planted in time after starting, and should be moisturized if they need to be transported over long distances.

Osmanthus species classification

1, four seasons osmanthus species: four seasons osmanthus bushy shrubby, low tree shape, branching short dense, crown spherical. New leaves deep red, old mature leaves green or yellow-green.

Osmanthus is in the months of flowering

1, golden laurel: flowering period of September to October, the color of golden yellow. Silver laurel: flowering September to October, the color white or yellowish white. Danggui: flowering in October, the color orange-red or orange-yellow. Four-season laurel: a small number of flowers every month, the color is white. In addition osmanthus according to the different planting areas will also lead to a slight difference in the flowering time. Shanghai, Anhui and Jiangsu that is basically open in October, the northeast of that area is basically open in August, Beijing, Tianjin, Hebei area is September, Sichuan, Guangxi and Shaanxi area is open in September.

2, osmanthus less than the age of flowering is not flowering. Osmanthus has a long life span, generally can live for decades to hundreds of years, some even live to a thousand years, so its flowering age is also relatively late. Sowed seedlings will bloom in about ten years, cuttings will bloom in four years, grafted osmanthus and silver osmanthus will bloom in one-fifth of the following year, and grafted four-season osmanthus will bloom in the same year, but the number is very small. Transplanted large osmanthus trees can bloom that year, some have to adapt to one or two years to bloom.

How much does a laurel tree seedling cost

1, varieties: the varieties of the laurel tree seedling determine the price of the laurel tree seedling, laurel is divided into four varieties of gold laurel, silver laurel, danggui and four seasons laurel, of course, each big variety inside a lot of small varieties, but the price of large varieties of small varieties below are similar to the price of danggui the highest price, the opening of the red flowers.

2, size: osmanthus sapling also have big and small, big price of course a little more expensive, seedling, now the industry is generally in accordance with the height of the sapling to distinguish between the size of the (previously in accordance with the age of the tree), on the current general planting is generally the most about one meter height of osmanthus sapling.

3, origin: the origin of osmanthus saplings and prices have a great relationship, because the relationship between the region is the first place to cultivate osmanthus saplings cost is not the same, resulting in a slight deviation from the price, and seedling distribution and transportation costs also have a great deal to do with the region.

4, quantity: the number of osmanthus seedlings purchased and the price is also closely related, as we all know, anything bought wholesale price will certainly be cheaper.

Osmanthus how to raise to grow well

1, timely watering: osmanthus potting soil to master not dry not water, watering is watering through the principle, but spraying the foliage with water once a day. After the Qingming Festival will be moved to the open watering a thorough watering, summer watering in the morning and evening, winter watering before and after noon, so that the water temperature and soil temperature close to the cold and hot, pay attention to the water must not be stagnant.

2, reasonable fertilization: osmanthus to flower-oriented, should be supplied with adequate fertilizer. When the tips can be applied 1 to 2 times nitrogen fertilizer, bud differentiation and flowering before the application of phosphorus fertilizer. Fertilizer before potting soil should be slightly dry, and it is advisable to loosen the soil first, so that the absorption of fertilizer, fertilizer should be watered the next day.

3, inverted pots for soil: osmanthus every 2 to 3 years to invert the pots for soil, cut off part of the old roots and dead roots, the bottom of the pot on a layer of river sand or vermiculite for aeration and drainage, and placed in the base of rotting cake fertilizer fertilizer, fill the soil must be compacted. Soil ratio is not very strict, usually available garden soil, heaps of stable fertilizer and river sand each accounted for l / 3 formulated.

4, pruning and shaping: osmanthus shaping generally take the combination of climbing and pruning methods, it is appropriate to carry out after the fall, the tree shape is very poor plants can be in 2/3 or 3/4 of the entire top of the branches cut off, the branches of the plant is too dense to be thinning, should be cut off after the flowering of the long branches, withered branches, pests and insects, dense and weak branches.

5, overwintering management: osmanthus overwintering room temperature should be maintained at 0 ~ 5 ℃, relative humidity to maintain 50 ~ 80%. Cold indoor light in winter should be good, especially in early spring before the buds begin to bud, more requirements for full sunlight, the following year after the rain to arrange potted osmanthus out of the room. After leaving the room, first centrally placed in the outdoor leeward and sunny place, so that it gradually adapted to the external environment.

6, disease control: osmanthus common diseases are leaf spot disease, coal stain disease, algae spot disease, root rot, iron deficiency disease, etc., leaf spot disease, coal stain disease and algae spot disease can be sprayed with 0.5 Bordeaux solution or 5% carbendazim 500 to 1000 times to prevent and control, root rot should pay attention to keep the soil loose and permeable, do not accumulate water.

7, pest control: osmanthus common pests are leaf wasps, whiteflies, mites, long white mealybugs, yellow stinging moths and so on. Leaf wasps, whiteflies, mites can be sprayed with 40% Rogaine 1500-3000 times solution, mealybugs can be sprayed with 40% Rogaine 1000 times solution or 40% Fenitrothion 500 times solution in the first two generations of insects in addition to manual brushing.

Osmanthus bonsai pruning method

1, ornamental pruning, refers to the osmanthus bonsai molding, in order to maintain, hold modeling osmanthus beautiful form and pruning. This pruning is long-term. A large number of, must be carefully done.

2, with the stump cultivation of osmanthus bonsai, after shaping pruning, the trunk and main branches have been determined. The need for further processing pruning is the secondary branches and finer tertiary branches. These branches of processing pruning, to master the basic points are: a branch to have a certain degree of zigzag, each branch should be divided into long and short, to show the beauty.

3, pruning, the messy cross-branching, overlapping branches, parallel branches and opposite branches should be adjusted, that is, cut off one of its or thinning a cut one. For the branches left behind, the nutrients can be concentrated and grow thick. When the culture branch grows to a suitable thickness, and then the intensity of pruning, so that the shortening. Give birth to the second section of the branch. When the second branch grows to a suitable thickness, then cut. Later on, the second and fourth section of the branch in turn, etc. are also so dealt with. Generally leave two twigs on each branch. Branchlets a long and a short. After many years of pruning, the branch under the short, thick, strong and powerful, and gradually form the required tree shape.

Osmanthus seed sowing method

1, in the following year 2 ~ early April, when the seed crack white before sowing seedlings. The general use of strip sowing method, that is, in the seedbed for horizontal or longitudinal grooves, ditch width 12 cm, ditch depth 3 cm; in the ditch every 6 to 8 cm sowing 1 germinated seeds. When sowing seeds, the seed umbilicus should be placed sideways so as not to bend the embryonic roots and young stems, affecting the growth of seedlings. In Guilin, usually with a wide strip sowing, row spacing 20 ~ 25 cm, width 10 ~ 12 cm, 20 kg of seed per mu, can produce 25,000 ~ 30,000 seedlings.

2, after sowing the seeds should be covered with fine soil, cover the thickness of the soil to not more than 2 to 3 times the cross diameter of the seed is appropriate; cover the soil leveling beds, so as to avoid stagnant water; and then covered with a thin layer of straw, in order not to see the degree of soil, and open the rope pressed tightly, to prevent the cover of grass is blown away by the wind; and then sprayed with water with a fine spray can fully to the soil until the soil is wet. Cover grass and water spraying can keep the soil moist, avoid soil crusting, promote early germination and early emergence of seeds.

How can I make osmanthus bloom more?

1, choose a good potting soil: osmanthus prefer slightly acidic soil. Potted plants can choose to use 5 parts of mountain mud, humus 3 parts, 2 parts of sand mixed with modulation or half of the humus and sandy loam as culture soil. If the soil is too acidic, the growth will be slow and the leaves will be yellow. If you use alkaline soil, after 2 to 3 months, it can lead to leaf withering, or even death.

2, timely watering: osmanthus watering to master the "two less one more", that is, less watering before the new shoots, less watering on cloudy and rainy days, more watering in summer and fall dry weather. Normally watering to often keep the potting soil about 50% water content is appropriate. Rainy days should be timely drainage, in order to prevent water in the pot rotten roots, otherwise easy to "drown".

3, skillful fertilization: osmanthus like pig manure, flower proverb has "to get osmanthus fragrance, more pig manure tank". If you can get out of the room from the early spring osmanthus, that is, the application of rotted thin hog manure liquid, April to May about every 10 to 15 days Shi 1 time, June to July every 7 to 10 days Shi once, early August Shi last time, the osmanthus growth is lush, flowering more and flavorful. The city does not have pig manure, available rotted cake fertilizer liquid. If the fertilizer is not enough, the branching is less, the flower is also less, and not fragrant.

4, appropriate pruning: osmanthus root system developed, sprouting strong, adult osmanthus tree, twice a year. Therefore, in order to make osmanthus flowers and foliage, the need for appropriate pruning, to maintain the physiological balance of reproductive growth and nutrient growth. Generally should be cut to the long branch, weak branch, disease branch, in order to facilitate ventilation and light, nutrient concentration, promote osmanthus breeding more, more full of flower buds, then bloom luxuriantly.
