One, cultivation time, osmanthus cultivation is generally in the fall or spring has not sprouted before potting.
Second, the preparation of potting soil, pot planting osmanthus has great limitations, pots are a special small environment, no matter which soil is used alone, can not meet the needs of potted flowers on all aspects of the soil, so the pot cultivation of osmanthus must be manually formulated cultivation of soil, used in place of the soil will be fixed in the flower pots, and a certain degree of water retention, drainage, loose, fertile, good drainage and good air permeability. The soil should be loose, fertile, well-drained, breathable, rich in humus and not too alkaline. Cultivation of osmanthus with the culture of the soil is generally used three parts of garden soil, two parts of coal ash or coarse sand, one part of humus or household garbage formulated. Or 75% of humus soil or garden soil, 25% of coal ash and coarse sand formulated.
Three, pots cultivation osmanthus selection of pots to be relatively large, pot size should be commensurate with the crown diameter of osmanthus plants, the general selection of biennial plants 20-25 cm in diameter pots, three-year seedlings selection of 30 cm in diameter or more pots, pots are small, nutrients and water to meet the needs of the plant.
Four, cultivation, in the bottom of the pot pad gravel or coarse sand to facilitate drainage, and then fill in the culture soil, the osmanthus plant into the pot in the center of the upright, the root system should be stretched out, add soil should be pressed tightly in layers, fill the soil to the half of the pot will osmanthus plant gently shaking, compaction culture soil, planting should not be too deep, potting soil from the mouth of the pot 2-4 cm as well, watering after potting After changing pots, water it thoroughly once. After changing pots, the planted osmanthus will be placed in a ventilated cool place to maintain for about 10 days, and then according to the daily method of management after the recovery of osmanthus.
Fifth, water and fertilizer management, in the osmanthus issued new leaves moved to a ventilated sunny place, to keep the potting soil slightly moist, watering the principle of dry and wet, avoid watering too much and waterlogging in the pot. In the summer heat, the soil is dry, to appropriately increase the number of watering, the flowering period watering should not be too much, so as not to drop flowers. Winter should also control watering, so as not to fall leaves, affecting the next year's flowering. After the rainfall, we should pour out the stagnant water in the basin in time. In the growth period every 7 days or so to chase the application of dilute human and animal feces water. Before the flowering of the June-August application of phosphorus and potassium fertilizer-based fertilizer. After flowering you can apply dried hog manure, about one or two per pot. It is best to change the soil every year, every 2-3 years to change the pot.
Sixth, osmanthus pruning, osmanthus plastic pruning more in early spring, every year after the flowers withered cut the densely overcrowded interior branches, slender branches, pests and diseases, dead branches, so that osmanthus tree ventilation and light good. Pay attention to the control of the upper strong and lower weak, to achieve a balanced tree on the crown, but can not be heavy pruning, to gradually cultivate and become.
Seven is winter management, after the winter need to enter the room osmanthus, indoor temperature should be maintained at 0-5 ℃, the temperature is too high is not conducive to flowering, while the humidity is maintained between 50-80%.
Eight, pay attention, osmanthus intolerant of soot, in soot more places often poor growth, leaves become smaller and easy to fall off, and less flowering.
