yes. It is not suitable for osmanthus trees to be potted on the terrace. Osmanthus fragrans is not strong in cold tolerance. If it is planted in the yard, their cold tolerance will be stronger, but you are all potted, and Osmanthus fragrans has low cold tolerance.
In order to make the osmanthus safely overwinter, it should be kept at -5℃ in winter and given sufficient sunshine. When placed, osmanthus fragrans should be exposed to sunlight to the maximum extent.
if it cannot be directly exposed, it should be placed in a place with strong light to receive scattered light. In addition, osmanthus fragrans should be placed in a place where the air is relatively stable, not in an air circulation place, so as to avoid being hurt by the invasion of cold air.
at the turn of autumn and winter, the temperature gradually decreases, and osmanthus fragrans can gradually adapt to the low temperature environment. If you enter the room too early, the cold resistance potential of osmanthus fragrans will not be fully exerted. After low-temperature exercise, the cold tolerance of osmanthus fragrans will be significantly improved, and it will be fully dormant in winter and flourish in the coming year. Usually leave the room after Qingming. At the beginning, it is best to move out of the house during the day and move back indoors at night.
