Propagating Mandevilla from Stem Cuttings

Rooting Mandevilla Cuttings: Tip Cuttings Work Best

That large piece accidentally severed from your Mandevilla vine won't root as a whole—but a tip cutting from it will readily propagate.

Successful Propagation Method

1. Select a 4–6" tip cutting with 2–3 nodes
2. Remove lower leaves; keep 1–2 top leaves (trim large leaves by half)
3. Dip cut end in rooting hormone powder (IBA 0.1–0.3%)
4. Insert into moist vermiculite or 50/50 perlite-peat mix
5. Cover with clear plastic bag (humidity dome)—poke ventilation holes
6. Place in warm (75–80°F), bright indirect light—no direct sun
7. Keep medium evenly moist; ventilate daily
8. Roots form in 3–4 weeks; transplant when roots reach 1–2"

Why Not the Whole Piece?

Large woody sections lack the hormonal balance and high auxin concentration of soft tip growth. They rot before rooting. Tip cuttings have active meristems and root readily.

Alternative: Layering

For difficult varieties, wound a low stem, apply hormone, bury in adjacent pot while attached to mother. Sever after rooting (6–8 weeks). Higher success rate.
