Potato Onions (6 Bulbs)
An heirloom onion originally listed in Australian seed and bulb catalogues back in the 1800s, this clumping perennial onion is rarely offered for sale in shops as it's production is best linked to hand planting and harvesting - so it's perfect for home gardeners. Each bulb produces up to 10-12 onions, so a few potato onions go a long way. A long term crop, potato onions are planted in autumn and harvested in spring (approx. 6 months). Stores well, lasting 4-6 months.
How to grow
Plant in rich, well-drained soil in a sunny position. Add compost or well-rotted manure prior to planting. Plant onions at soil level (half exposed) and around 20cm apart. Sprinkle with some blood and bone and water in well. Keep moist, but not wet. Harvest potato onions when the tops fall over and begin to dry. Stores well, lasting up to 12 months in the right conditions. Replant the smallest bulbs after harvest or wait until the following autumn or spring.
