I ordered some red onion (variety Red Zeppelin) from Johnny’s seeds and expected to receive some onion sets (the miniature onion type) but these came instead. They are dormant starts.
As I understand it they are plants started from seed, grown during the winter then uprooted when the weather gets cold. The soil is knocked off and they are kept in cold storage like this until Jan/Feb when people like me buy them and plant them in their gardens. So in effect they are onion seedlings that have been grown for me.
It’s interesting. I’ve never grown onions like this before so I’ll be watching closely to see what difference they make. I have bought some conventional sets just to make me feel safe. I fear change, really I do!
