About Zumi crabapple
Malus zumi, known as "ō-zumi", is a charming small ornamental crabapple tree native to Japan, prized for its profuse spring bloom of white flowers and its tiny red fruits that persist well into winter. Its compact and elegant habit makes it ideal for small gardens, as a specimen plant, in hedges, or even in large pots on patios and terraces, providing lasting seasonal interest. Its berries, though small, are a visual and food feast for local wildlife.

Care tips
It prefers a full sun exposure to ensure optimal flowering and fruiting, although it tolerates some partial shade. It requires well-drained, fertile, and slightly acidic soil; make sure to water regularly during dry periods, especially in its early years. Avoid waterlogging, as it is susceptible to fungal root diseases. A common mistake is not pruning the suckers that emerge from the base, which can weaken the main tree.
