When will Tianmu Mountain sweet potato be listed?

July. Small fragrant trees in Tianmu Mountain began to be listed in July every year, and were intensively sold in July and August until the end of 10. I want to buy authentic Tianmu Mountain sweet potato, and look for the purchase opportunity from July to 10. Tianmushan sweet potato is a precious variety cultivated by Zhejiang Academy of Agricultural Sciences and Zhejiang University from thousands of sweet potato varieties, with red skin and yellow heart, paper-thin skin, no silk and no tendons and excellent quality. Sweet potatoes in Tianmu Mountain are planted in the most traditional way. Every household plows the fields with cattle, sows by hand, picks and digs with hoes, and grows for 85 days. No pesticides are used in the planting process. The average yield per mu of sweet potato is 1500 kg, but there are too few varieties of sweet potato, which requires high planting environment, and the yield per mu is only 700 kg, which is very precious.
