Hydrangea macrophylla
| Methods | Stem cutting, layering |
| Difficulty | Intermediate |
| Best season | Spring–summer |
| Time to root | 4–6 weeks |
| Group | Outdoor / garden |
Hydrangea roots well from softwood cuttings taken in late spring or early summer. Removing all but the top two leaves — and cutting those in half — reduces water loss enough to keep the cutting alive while it roots.
Stem cutting
- Cut a 4–6 inch non-flowering tip in late spring or early summer.
- Remove all but the top two leaves; cut those in half.
- Dip in rooting hormone.
- Insert into moist, well-draining mix; cover for humidity.
Layering
Pin a low, flexible branch to the ground; once rooted (a season or more), cut it free.
When to propagate
Late spring to early summer for softwood cuttings.
Common problems
Cutting wilted and died. Too much leaf surface relative to root capacity — trim leaves further and increase humidity.
Questions people ask
Will the new plant have the same flower color? Yes — cuttings are genetically identical to the parent, so flower color carries over, unlike seed-grown plants.
Is it toxic? Mildly — the leaves and buds can cause GI upset if eaten by pets or people. Nothing to worry about for normal handling and propagation.
