Sweet osmanthus likes sandy loam with good acidity, drainage and fertility. Sweet osmanthus grows slowly in strong acid soil, leaves are yellow and leaves are withered, and branches are few; in pH value 3-4 soil, the grafted two-year seedlings have two branches and three branches in the same year, and the branch length is only 6cm, which is two times less and one to two times shorter than that in pH value 6 soil.
In alkaline soil, withered ginger appeared in two or three months and died gradually.
Osmanthus likes pig manure. It can be mixed in the basin soil, or it can be applied at the bottom of the basin after being decomposed and dried. The amount of fertilizer applied shall be 1 /4 of the basin height. A layer of 1-2-inch-thick soil shall be covered on the fertilizer, and then four seasons osmanthus shall be planted. No more fertilizer shall be applied within one year.
In places where there is no pig manure in the city, it can be used to retouch the hoof horns of donkeys, horses and mules into water. It should be watered once in spring when it germinates. Before August, it should be watered every 7 days and 10 days. It can also be used to stir fry sauce residue and soybeans, stir fry raw peanuts, grind into noodles, and dig ring root holes and bury them in pot soil. According to the observation: if you are fat enough, the flowers will be prosperous and fragrant, and the number of flowers will be 2-3 times more. Not enough fertilizer, less branches, less flowers, flowers are not fragrant.
The watering of Sweet osmanthus should be controlled two less and one more: the plants that change pots before new shoots occur should be watered less, rainy days should be watered less, and dry days in summer and autumn should be watered more early. After the basin is changed for water permeability, the water content of the soil should be about 50% and 60% in the dog days (July to September). Identification method: use your hand to knead the pot soil to form a mass. Put it down and spread it. Pay attention to drainage in rainy days to prevent ponding and rotten roots. It has been proved that Sweet osmanthus is easy to die when more than 90% of soil water is accumulated.
At the same time, keep the air humidity. Put osmanthus in the shade, spray water on the leaves every morning and night. Or put a fish tank or small basin with water beside it, and put osmanthus in the open air to withstand the night dew and increase the humidity to keep the leaves fresh.
The process from high temperature to low temperature to high temperature is needed for the flower bud formation and differentiation to flowering. The flower bud began to differentiate at about 30 ℃ in high temperature, formed in 25-31 days, and began to sprout after 3-5 days of low Ju dormancy at about 15 ℃. After bud sprouting, it blooms quickly at 25'c or above.
Osmanthus is mainly leaf, type and flower. The flowers are small but fragrant, mainly with beautiful leaves and shapes. Modeling should show prosperity, solemnity, elegance and innocence. You can choose Ligustrum lucidum as the rootstock, first move the large leaf Ligustrum lucidum to the flowerpot, from the summer solstice to the autumnal equinox, you can graft by grafting, that is, you can graft the branches of Sweet osmanthus on the Ligustrum lucidum branches, and remove the branches of Ligustrum lucidum.
After survival, cut the osmanthus from the mother. L to form a new osmanthus. The general survival rate can reach 100%. Some privet rootstocks are not beautiful in shape. You can select them first, such as bows, twists, etc., and then connect them according to your hobbies. Where there is no place for Ligustrum lucidum, Ligustrum lucidum can be used as rootstock. After the osmanthus is connected, watering cannot be ignored, just like normal management.
