Conifer Cutting Propagation: Need Stronger Hormone

Leyland cypress and fir cuttings are difficult; standard Rootone is too weak.

Recommendations

• Use concentrated liquid rooting hormone (e.g., from rooting-hormones.com).
• Take semi-hardwood cuttings in late summer.
• Provide bottom heat, high humidity, strict sanitation.

Conifers require higher auxin concentrations. Consult technical resources for exact rates.
