Rowan Tree (Mountain Ash) Propagation and Storm Damage Assessment

Propagating Rowan from Cuttings

Rowan (Sorbus aucuparia, called Mountain Ash in North America) propagates well from green wood cuttings taken in spring after last frost.

Cutting Protocol

1. Select 6-8 inch (15-20 cm) green wood cuttings
2. Strip all but top 2-3 leaves
3. Dip in rooting hormone (Rootone)
4. Stick in moist, warm sand
5. Maintain warmth and humidity
6. Rooting begins ~8 weeks; check by gentle probing
7. Pot up when significant roots develop
8. Harden off 10 days in shade before planting out
9. Plant in full sun (8+ hours)

Assessing Lightning-Damaged Trees

Bark stripped entirely around trunk circumference (girdling) destroys phloem transport. Even with crown leaf-out from stored reserves, the tree is structurally compromised and likely dying internally.

Safety Evaluation

• Consult certified arborist for professional assessment
• Internal decay may not be visible externally
• Risk of sudden failure increases over time
• Near play areas: err on side of removal

Scottish Context

In west central Scotland's climate, rowan thrives naturally. The folk song "Rowan Tree" celebrates this cultural icon. Local nurseries offer seedling stock adapted to your conditions—often easier than cuttings.
