If you want to use turnips why not?
I use both... I have grown turnips in the past, real easy but it now gets to warm in the winter...
3rd time in 4 years we hit 80+ in Feburary that was enough for me-they bolt, turn to seed & were so bitter the pet bunny shock his head & hopped off... The bulbs are still good, but small.
Do you cook that Welsh stew??
