Onion - Rossa Lunga di Firenze
This is a mild salad onion which becomes increasingly pungent as the bulbs mature, and can be used at any stage. Often roasted on skewers to retain its unusual 'bottle' shape.
Sow thinly outdoors from March to September, where they are to crop, 1.5cm deep, directly into finely-prepared, well-dug, fertile soil, which has already been watered. Allow 15cm between rows. Seedlings usually appear in 14-21 days. No thinning is required, but keep well-watered in dry spells. Regular sowings, made every three weeks, will ensure a continuous supply through the summer. Harvest from March to October. August to September sowings will be ready the following spring.
