Red Rambo is a quality globe shaped red onion with dark outer scales and an impressive red internal colour.
Bulbs are large but like all red onions only have a moderate storage life. We recommend spring as the best sowing time (July to August) - you should be harvesting your crop as early as February! Other sow dates can work and maybe worth a try in your area. Plant spacing has a huge influence on bulb size. For bigger onions space out to 10cm.
