help! first time onions, way too small
I bought yellow and white onion sets at my local co-op. I have never grown onions and wanted to try them. I planted them with about 1/3 of the top above ground in a raised bed. As they started to grow I removed soil from around the bulb. They all fell over about 2 weeks ago, some of them the leaves are all dead and gone, and the bulbs are tiny! They are about 1.5" across, and kind of flat.
WHAT DID I DO WRONG???
