Proper placement According to the growth characteristics of osmanthus fragrans, it is better to place it on the southeast balcony. If you must put it indoors, you should also choose it in front of the southeast doors and windows, so that you can receive the light to the maximum extent.
How to water potted osmanthus, from late autumn to early spring, wait until the pot soil is slightly dry or the leaves are a little wilted, and then water it once and for all. During the vigorous growth period in late spring and early autumn, water more. If you have no experience, you can water it once when the leaves are wilting, or wait until the surface of the pot soil is white and slightly cracked. Generally, when it is hot in summer, you can water it twice a day, once in the morning and once in the evening. It should be noted that if there is too much water supply, it will cause falling flowers. It is difficult to control the watering for family flowers. The most mechanical method is not to dry (wither) without watering, but to water thoroughly. When there is too much water, the leaves turn yellow.
How to apply fertilizer after the spring? Fertilization should be started when the temperature rises above 15℃ at night. At this time, branches begin to grow and need fertilization. If compound fertilizer is used, the application amount is 4g each time (about a bottle cap of a small mineral water bottle), four small holes are drilled around the basin soil, the compound fertilizer is evenly put down, and then the soil is covered (the position should be changed when drilling next time), and the fertilizer is applied every 10- 15 days, and the fertilization is stopped when the temperature drops below 8℃ in autumn night. If organic fertilizer such as cake fertilizer is applied, the dosage per time is 65438+ 0/3 of the bowl (without water). If you buy packaged flower fertilizer from a flower shop, just follow the packaging instructions. If there is no packing instruction, ask clearly. Stop fertilizing as soon as the buds grow out. Overnutrition will cause buds to fall off (except Sijigui).
Adjusting the temperature osmanthus is a little afraid of cold and heat. It grows only when the temperature is above 15℃ at night. For the northern region, to make it bloom during the National Day, it is necessary to move indoors before August and autumn, keep the temperature above 15℃, stop fertilization, water less (water after wilting), and then move out for maintenance in mid-September before it can bloom during the National Day.
It is difficult to find some flower soil in the city now, so you can make it yourself. 5 bowls of garden soil (made on site) 1 bowl of yellow sand. If you can get some sawdust, you'd better add 1 bowl. If there is no sawdust, use half a bowl of yellow sand instead. This is just to provide a ratio. Stir these things thoroughly and evenly, and the flower soil will be ready.
The reason for ventilation is that natural air circulation can increase the air humidity around potted flowers, increase the content of carbon dioxide around leaves, and recycle the air around leaves with germs (we will notice that moldy air is mostly a closed small space, and the air is not circulated, which is very conducive to the reproduction of various germs. This is the same as "running water does not rot"), which makes potted flowers less likely to get sick. Now many residential buildings have closed doors and windows, and the air is not circulating, especially in air-conditioned rooms. In order to save energy, the air conditioner only circulates indoor air and does not exchange with outdoor air, so its air will become more and more stale and the air humidity will be very low. Therefore, it is good for flowers and people to open doors and windows for ventilation sooner or later.
How to prune before the temperature rises above 15℃ in spring, and use household scissors or sharp blades to cut off dead branches, twigs and branches with pests and diseases, so as to make way for new branches and not give opportunities for pests and diseases to propagate. Combined with the tree shape, in the growth period, a small number of unwanted new branches are removed, and limited nutrients are concentrated to make the flowers more lush. This is the same as people, "many children make the mother bitter." But be careful, you can't cut off all the new branches, because only new branches can grow flower buds. After the flowering period in beginning of autumn, it is necessary to combine the tree shape, thin some branches that are too dense, and cut off some branches that are particularly high.
Propagation method: When the temperature rises to above 15℃ in early spring, the unbranched branches are cut to a length of about 10- 12 cm, with at least three leaf nodes or bud eyes, and inserted into a flowerpot filled with half a pot of nutrient soil with a depth of 1/3 (about 3-5 cm During the period, the film is exposed every 5-7 days for ventilation (one hour), and generally no water is needed. If it is too dry, you can spray some water with your mouth.
Pest control If pests are found, household spray insecticides can be used; When diseases are found, the diseased leaves or branches are directly cut off.
Post-flowering treatment
Osmanthus fragrans can grow well if the pots are turned over and maintained according to the above method. After the next spring, osmanthus will be replaced with a slightly larger flowerpot. Put 3 cm of nutrient soil at the bottom of the big basin, add two caps of compound fertilizer and spread evenly; Then put the osmanthus down, cut off the root system outside the hole at the bottom of the pot, gently shake it a few times, pull it out together with the soil lump, be careful not to spread it out, put it in a big pot, add soil, press it slightly, and pour water.
