I spotted this onion sprouting a leaf in our fridge and decided that, as it was growing despite the cold, I would give it a chance at life. So, out the fridge it came and into an espresso cup, with some water, it went. The leaf has now doubled in size and I’m going to put the onion into the ground but have a question (it is the first time I’m growing one). Will the onion plant produce many small onions? And when will I know when to harvest?
