They like rich soil made up of sand or mud. Let's face it mud is a wonderful thing to those bunnies and kids who don't mind getting a little dirty. It takes about 100 days to grow a crop. They are a hardy vegetable. They are rich in Carotene which is full of goodness like Vitamin A, B1, B2, and more.
Carotene is good for eyesight.
So, it is important to grow, eat and protect this precious food for every critter. Which reminds me, you gotta beware of carrot caterpillars, they are not a bunnies best friend. I guess they do something useful in the world though, every living thing does. I just don't know what it is. Grammaw says every living thing is a thread in her tapestry and every thread matters to the design.
