Cinnamon on Plant Cuttings: Does It Actually Work? (Science Check)

What Cinnamon Actually Does

Ground cinnamon contains cinnamaldehyde, a compound with mild antifungal properties. Applied to fresh plant cuts, it can:

• Slow the spread of common fungal infections on cut surfaces.
• Mildly disinfect wounds.
• Reduce rot likelihood in propagation.

What It Doesn't Do

• Stimulate root growth (no rooting hormone effect).
• Replace proper sterile cutting tools.
• Cure existing rot or major infections.
• Speed up healing significantly.

How to Use It Correctly

Dust the cut end of a cutting LIGHTLY with cinnamon immediately after cutting. Use only fresh, pure ground cinnamon (not the artificial 'cassia' variety). Combine with sterilized scissors and dry callusing time for best results.

Frequently asked questions

Is cinnamon better than commercial rooting hormone?

No — they do different things. Cinnamon prevents rot; rooting hormone (e.g., Hormodin) accelerates root formation. Use both for best results.

Can I use cinnamon on root rot?

It helps prevent SPREAD of new infection after you cut out rotting tissue. It does NOT cure existing rot — surgical removal is required first.
