About Japanese mountain cherry
Prunus jamasakura, known as yama-zakura, is one of the most iconic wild cherry tree species in Japan, cherished for its five-petaled blossoms ranging from pure white to pale pink. This medium to large deciduous tree features beautiful smooth bark and foliage that emerges simultaneously with the flowers, creating a stunning natural display. It is ideal for large gardens, parks, or as an ornamental tree in landscape settings, bringing elegance and a touch of Japanese spring.

Care tips
Yama-zakura thrives in full sun, requiring at least 6 hours of direct sunlight daily for optimal flowering. It needs well-drained, fertile, and slightly acidic soil; avoid heavy, clayey soils that retain too much moisture. Watering should be regular during dry periods, especially in its early years, but it's crucial to avoid waterlogging, as it is susceptible to fungal diseases. A common mistake is excessive or incorrect timing of pruning, which can reduce flowering and stress the tree; prune only to remove dead or diseased branches, preferably after flowering.
