Propagating Delphiniums from Cuttings: A Detailed Guide

Why Cuttings?

Delphiniums are short-lived perennials (3–5 years). Cuttings preserve the exact cultivar, unlike seed which may vary.

Procedure

1. Take 6–8 inch cuttings in late spring.
2. Remove all but a few top leaves.
3. Dip cut end in rooting hormone (e.g., Rootone).
4. Insert into moist soilless mix.
5. Keep warm, mist 2–3 times daily.
6. Roots form in a few weeks; check by gentle probing.
7. Pot up individually; feed with 12-12-12 every 10–14 days.
8. Harden off for a month in shade, then plant in full sun, well-drained soil.
