Biological Mechanism & Horticultural Rules

Dormant scions can lose viability through freezing, warming, dehydration, excessive free moisture, decay, or exposure to ripening produce. A separate clean refrigerator reduces variables, but visual condition and bud status must still be inspected.

Assumptions & Physical Constraints:

Assumes dormant, healthy, correctly labelled one-year wood in a clean sealed bag with no standing water. Storage life varies by species, collection date, material condition, refrigerator stability, and grafting date.

Lower-risk setup: cold but nonfreezing storage + barely damp wrapping + a clean bag away from ripening produce. Inspect periodically for condensation, mold, shriveling, or bud movement.
Rule-set status: Rule set 4.1 • Reviewed August 2026

Frequently Asked Questions

Can I store scions in a freezer?

No. Standard household freezers cause freeze-desiccation (sublimation) of wood moisture unless specialized commercial cryogenic packaging is used.
