About Japanese maple
Acer palmatum, commonly known as the smooth Japanese maple, is a small to medium-sized deciduous tree cherished for its graceful form, deeply lobed leaves, and spectacular autumn colors. Its foliage, which can range from bright green to deep burgundy, offers a continuous visual display. It is ideal for small gardens, as a standalone ornamental tree, or in large pots on patios and terraces.
Native range
Japan, Korea, China, and southeastern Russia
Care tips
It prefers a location with partial sun or light shade, especially in warm climates, to protect its leaves from sunburn. Watering should be regular and moderate, keeping the substrate moist but not waterlogged, especially during dry and hot periods. It requires well-drained, slightly acidic soil rich in organic matter. A common mistake is inconsistent watering or exposure to intense full sun, which can lead to wilting and leaf scorch.

- First aid
