Starting
Sow 5mm-1cm (¼-½") deep in rows spaced 45-60cm (18-24") apart, and thin to 10-15cm (4-6") apart in the row.
Growing
Ideal pH: 6.0-6.8. Humus-rich, deeply cultivated soil is key. Add plenty of well rotted compost or manure to th ebeds and cultivate to a depth of 20cm (8"). Dig in 1 cup of complete organic fertilizer for every 3m (10') of row. The real secret to success with turnips is speed. Sow short rows every 2-3 weeks, thin them quickly, keep them watered, harvest, and then sow some more.

Diseases & Pests
Remember that turnips are members of the Brassica family, so they should not be planted where other Brassicas have been grown in the past 4 years. This simple crop rotation will prevent nearly all diseases from occurring in the first place. Floating row cover will protect plants from cabbage moth and flea beetles.
