Spring Onion

Allium fistolosum - "Ishikura" from Kings Seeds

Germinates in soil temperatures of 10-25°, direct sow around 5 to 10cm apart and 1cm deep, takes 7 to 14 days to germinate, then 10 weeks to harvesting.

Last year I did this all wrong – transplanted them into a terracotta planter in the mini greenhouse. They were edible after 8 weeks but the stalks were only 10cm high then, and they should get to 45cm according to the Kings catalogue. After 12 weeks the bulb had gotten larger but the stems hadn't progressed upwards at all. Tasty though!

This year I've earmarked the spring onions to go in the area that had cover crops in. Successive sowings will be called for – maybe 3 or 4 each fortnight? I decided to start with half a dozen sown this morning.
