Here is what
JL Hudson has to say about their mangels:
MANGEL WURZEL
Beta vulgaris. A type of beet usually grown for stock and poultry feed, but used as
a delicious table vegetable when young and tender. Cooked, the texture is that of
tender beets, but the flavor is more potato-like, with a delightful touch of sweetness.
If you find ordinary beets too strong, try this kind. The roots are globe shaped or
elongated, with red or yellow skin, and white or pale yellow flesh.
Mangels can be grown in almost any soil, but a well-prepared rich loam is best for a
heavy yield of the long kinds. Sow as early as ground can be worked, in rows 2 feet apart.
Thin to 6" apart when seedlings have developed 4 leaves.
USDA Germination Standard: 65%.
