Propagating Japanese Aralia (Fatsia japonica) from Stem Cuttings

Fatsia japonica Propagation: Stem Cuttings Work Well

Japanese Aralia (Fatsia japonica) propagates reliably from tip stem cuttings in shade gardens.

Propagation Protocol

1. Take 4–6" tip cuttings (semi-hardwood, current season's growth)
2. Critical: Do not touch newly emerged leaves—they're extremely fragile
3. Dip cut end in rooting hormone (IBA powder)
4. Insert into moist vermiculite or 50/50 perlite-peat
5. Cover with humidity dome (bag with holes)
6. Place in morning sun / dappled shade
7. Keep medium damp, not soggy
8. Roots in 4–6 weeks; transplant when roots 1–2"

Alternative: Air Layering

For larger pieces: wound stem, apply hormone, wrap with moist sphagnum + plastic. Roots in 8–12 weeks. Higher success for difficult clones.

Care Notes

• Fatsia prefers shade/part shade, consistent moisture
• Protect from drying winds
• Fertilize lightly after establishment
