Prunes require high planting environment, and there are few areas that can be planted and have high yield, so this is one of the reasons why prunes are expensive. In China, Xinjiang has unique geographical conditions conducive to plum blossom growth, and plum blossoms are planted in Kashgar, Yining and Hotan. Generally, August-September is the main harvest period, with an annual output of about 1,000 tons.

After years of demonstration in Guanzhong and Weibei of Shaanxi Province, it was found that plums can be cultivated in mountainous areas, sloping fields and beaches, but it is better to cultivate them in loose soil with smooth drainage.

Dried prunes are native to southwest France, which is the hometown of prunes. When ripe, the peel is dark purple and the pulp is amber. 1848, a French planter came to California to look for gold. 1856, plum seedlings were introduced to North America and grafted with the original species of Degen plum. The grafted trees came to California in the same year.
