What conditions (weather) do osmanthus trees need to bloom? When will the osmanthus trees in Hunan and Hubei bloom this year?

I come from Hubei. Well, it opened in August and September. I don't know the terms. It's only been a few days anyway, but there seem to be several kinds of osmanthus. Well, the temperature in autumn is just right!

Osmanthus fragrans usually blooms at the beginning of 10. If we want to promote its flowering in advance, we can treat it at 13 ~ 16℃ 10 ~ 14 days. If we want to delay the opening time of osmanthus fragrans, we should move it into the greenhouse above 18℃. High temperature will inhibit the germination and flowering of osmanthus fragrans flower buds.
