Propagating Fruitless Mulberry: Cuttings Preserve the Trait

"Fruitless" mulberry (Morus alba 'Fruitless' or 'Kingan') is a male clone—cuttings preserve the non-fruiting trait. Seeds do not.

Why Cuttings Work

• The parent is a selected male cultivar. Vegetative propagation (cuttings) produces genetic clones—also male, also fruitless.
• Seeds result from cross-pollination; offspring will be mixed male/female and will fruit.

Cutting Protocol (Late Spring/Early Summer)

1. Take 6–8 inch greenwood cuttings (flexible, not woody).
2. Strip all but top 2 leaves.
3. Dip in rooting hormone (IBA 0.1–0.3%).
4. Stick 1 inch deep in moist sand or soilless mix.
5. Cover with clear plastic; bright indirect light.
6. Maintain warmth (70–75°F) and high humidity.
7. Check for roots in 8+ weeks (tug test).
8. Harden off, pot up, plant out next spring.

Alternative: Buy a Named Cultivar

If cuttings fail, purchase 'Fruitless', 'Kingan', or 'Stribling' from a reputable nursery—guaranteed male, guaranteed fruitless.

Take cuttings now; you'll have shade trees without the mess.
