"Autumn inaccessible" means that entering the room should be late or not. Under normal circumstances, the cooling rate at the turn of autumn and winter will not be very large. As long as the temperature is not lower than -1°C, potted osmanthus will not be problematic for 4 to 5 days in the open air. After low-temperature exercise, the cold tolerance ability of sweet-scented osmanthus will be significantly improved.
"Frost in winter" means that osmanthus should be protected from frost damage as much as possible. North winter conservation can take the following measures:
One is to put potted osmanthus directly in the greenhouse, the room temperature is not higher than 3 °C, and promote it to sleep. Place the osmanthus to the maximum exposure to sunlight when placing it. If it is not in direct sunlight, place it in a place where light is strong enough to allow it to receive scattered light. In addition, osmanthus should be placed in a relatively stable air, do not place in the air circulation, to avoid the damage caused by cold air.
The second is bagging. Bagging should not be premature, and bagging will begin when the minimum temperature reaches -5°C. Using a thick transparent plastic film, rectangular bags are made according to the crown width and height of osmanthus flowers, and the flowers and pots are put in with the bag mouth facing up. Pot holders (with bamboo, wooden sticks, branches, etc.) should be used so that the bags do not cling to the leaves so that they do not suffer frostbite. When there is no wind and warm weather, the bag mouth can be unlocked to allow the sweet-scented osmanthus to receive the sun, ventilation and ventilation. After the spring, as the temperature rises, the bag mouth can be gradually opened to adapt the osmanthus to the outside environment. When the temperature is stable at around 5°C, the bag can be removed.
"Spring Festival Evening Out" means that the sweet-scented osmanthus out of the room should not be earlier. If you move directly out of the house, you can easily cause potted osmanthus wilting. In April, the weather was obviously warmer and the osmanthus in the room had to be moved outside. In order to adapt itself to the outdoor environment, open doors and windows at noon every day before leaving the room to allow the air to circulate and allow the sweet-scented osmanthus to savor the sun. Usually after the Qingming out of the room. In the early days, it is best to move outside during the day and back indoors at night. Go back and forth for a few days until the osmanthus gradually adapts to the outside environment and then outdoor.
