How to care for Japanese Aralia
Fatsia japonica · Araliaceae
A bold shrub with big, glossy, hand-shaped leaves that brings an instant lush look to cooler, shadier rooms where tropical plants sulk. Native to Japanese woodlands, it actually prefers cool temperatures and gentle light. It grows fast and can become an impressive indoor specimen in a couple of years. Water roughly every 5 days while it's growing (about every 10 in winter), give it a bright room away from the window, kept above 41°F (5°C) — average room humidity suits it.
Care at a glance
Keep the soil lightly moist in the growing season, watering when the surface dries; drooping leaves recover quickly after a drink.
Bright shade or a north or east window suits it; hot direct sun yellows and scorches the leaves.
Balanced liquid fertilizer at half strength every few weeks in spring and summer.
Mistakes that kill this plant
- Hot, dry air near heating vents, which brings mites and crisped leaves.
- Full afternoon sun through glass.
- Letting a large, thirsty specimen dry out repeatedly.
Seasonal tips
- It loves a cool winter room (8-15 C); avoid parking it next to radiators.
- Prune in spring to control size; it responds with bushier growth.
- Wipe the large leaves monthly so they can breathe and shine.
