Can Bailu solar terms still graft Luan trees?

I don't think so, because the fruit of Luan tree ripens in September ~ 10. Luan tree, also known as wood Luan and Luan flower, is a plant of Luanshu in Sapindaceae. Deciduous trees or shrubs; Thick bark, light gray brown to light gray black, longitudinally cracked when old; Small lenticels, gray to dark brown; Branchlets with verrucous spots, and leaf rachis and petiole are wrinkled pubescent or glabrous.

Luan tree grows in calcium-based soil produced by limestone weathering. In China, Luan trees are only distributed in the lower reaches of the Yellow River and the Yangtze River. It is rare in the northern part of Haihe River Basin, and it can't grow in silicon-based acid red soil area. Luan tree germinates late in spring and leaves early in autumn, so the annual growth period is short and slow. Wood can only be used to make small household appliances, and seeds can be squeezed into industrial oil.
