The Cost of Sprouting Onions

Sprouting turns firm, saleable onions into culls. A disciplined storage programme that applies onion sprout suppression keeps bulbs dormant, protecting shelf life and reducing waste for importers across the onion supply chain.

Curing and Dormancy First

Sprout control starts at harvest. Proper curing dries necks and scales, putting bulbs into dormancy and preparing them for long-term onion storage. Well-cured bulbs respond much better to dormancy management during export.

Temperature and Ventilation Control

After curing, our climate-controlled stores hold onions at low temperature with steady ventilation. This slows internal growth and supports onion sprout control without chemical treatments, giving buyers a clean product that stays saleable longer.

Handling for Export and Cold Transit

Onions destined for export are packed in ventilated bags and loaded into temperature-managed containers. Consistent conditions maintain foodservice onion storage quality from our warehouse to your destination, preventing premature sprouting in transit.
