Why are my turnips in the garden cracking and going to rot?
Why Are Turnips Cracking
Certified GKH Gardening Expert
Cracking like this is typically caused by inconsistent watering. If the turnip gets too dry and then is flooded with water, it takes up the water too fast and this causes the root to crack. Once it cracks, it is exposed to fungus in the ground, which is what causes the rotting.
