Fall-sown turnips are sweeter than spring crops because cold temperatures convert starches to sugars in the roots.
Harvest at 5-8 cm diameter for best flavor and texture; overgrown roots become woody and bitter.
Turnip greens can be harvested multiple times by cutting outer leaves, adding value to the crop.
