Always buy twice as many as you think you will need and either plant all closely or plant half in a separate bed one inch apart. Thin out or pull when large enough to use as spring onions from late April or early May onwards. Continue using as large spring onions and young ‘green’ onions. Delicious at any size and much sweeter and juicier than fully ripened onions. Also, start using some garlic young and green in late June. This is when it is at its best.
