Cultivation method of osmanthus fragrans potted in the north (how to maintain osmanthus fragrans trees in the north to make them grow well)

Most varieties of osmanthus are not cold-resistant. Only golden osmanthus is a cold-resistant variety. Most varieties of golden osmanthus can grow healthily at around -10 degrees Celsius.

Golden Osmanthus is the best variety suitable for planting in the north, especially the August Golden Osmanthus variety from Henan. Or you can use Golden Osmanthus as the grafting scion and Ligustrum lucidum as the rootstock.
