How to propagate by stem cuttings
Poinsettia roots from soft shoot tips taken in summer. The cuttings wilt easily, so they root under a cover in damp mix.
Wear gloves when you take cuttings. The milky sap can irritate skin and harm the eyes, and it can cause a reaction in people who are allergic to latex. Keep it away from your eyes and wash your hands afterwards.
- 1
In early or mid summer, cut a 10–15 cm (4–6 in) shoot tip from a healthy, growing stem. Do it in the morning, before the room warms up.
- 2
Rinse the cut end under lukewarm water until the milky sap stops running, then remove the lowest leaves.
- 3
Dip the base in rooting powder if you have some, then push it 2–3 cm (0.8–1.2 in) deep into a damp, light rooting mix with plenty of perlite or sand.
- 4
Cover the pot with a clear bag or lid to keep the moisture in, and stand it in a warm, bright spot out of direct sun.
- 5
Keep the mix damp but never soggy: wet mix slows rooting and invites fungus gnats and rot.
- 6
Roots usually form in 3–4 weeks. Then move each cutting into its own small pot and take the cover off over a few days.
