Abies growth

In summer and autumn, from June to September in the lunar calendar, Pinus massoniana stands alone or in groups, orange in summer and brown in autumn. When it is sunny and rainy in summer, I like to grow in the young Chinese fir forest (7 or 8 years old), but I also grow in the old Chinese fir forest, but the number is not much longer than that of the young Chinese fir forest. It also grows in autumn with low temperature and rainy weather, but it looks brown and looks the same as that born in summer, but the color is different.
