Pruning 'red baron' onion — FAQ
When should I prune 'red baron' onion?
No pruning needed; harvest when tops yellow and fall. Remove visibly diseased or damaged outer leaves by cutting at the base. Leave all healthy green growth intact. When tops begin to yellow and fall naturally, bend the rest over to complete curing before lifting.
How often does 'red baron' onion need pruning?
Rarely; only for damage removal. Red Baron onions do not require pruning. The red-skinned bulbs are fed by the green leaf tops throughout the season — cutting these prematurely reduces bulb size. Remove any yellow, rotting, or diseased leaves at the base if spotted. Allow tops to yellow and topple over naturally, which signals the bulb is mature and ready to lift and cure.
