Not only is the actual root of the turnip edible, but the green turnip tops that are produced can be eaten too. The turnip roots retain their nutrients well and can be cooked, and the turnip tops are great in salads, and can be boiled or steamed.
Turnip seeds need to be sown from May to July outdoors (For the turnip tops sow in August). The seeds need to be sown into raked soil in rows that are 30cm apart. Germination should happen within 6 to 10 days, and the vegetable should reach maturity within 6 to 10 weeks.
For continuous produce sow turnip seeds successional every fortnight so tender pure white roots can be pulled up regularly.
