A quick update after 3 months away from the garden. Around April I broadcast sowed a 2.5 metre bed with the seed from my seed seive tray that didn't get collected, the stuff that fell through the mesh.
The bed got thinned just before I left for my extended holiday in May, and had a few subsequent thins from the house sitter.
Most of the carrots (that may or may not be F1s, since they are the result of a mass interplanted mix of varieties which might have crossed, but also may have selfed. Below, a handful of the thinnings from last week, showing a majority of yellows and whites, which might be because of dominant genes, the mix of varieties in the seed mix, germination success, or chance.
