Bolting is almost a thing of the past with this excellent globe beetroot! Detroit 6 : Rubidus will be ready to harvest over a week earlier than ‘Boltardy’, which it supersedes in all respects. Firm, smooth, deep red flesh without a hint of fibre, even when 12.5cm (5in) in diameter. Vigorous, high yields which are synonymous with F1 Hybrids.Sow seeds from spring to early summer very thinly in drills 3cm (1in) deep in rows 30cm (12in) apart.When seedlings are large enough to handle thin them out gradually to 1cm (4in) apart.The later thinnings will be large enough to use in a salad. Pull the beetroot when the roots are 4cm (1½in) in diameter or larger. The smaller the roots the better the quality. In mid autumn lift the remaining roots, twist off the tops and use or store in a clamp as you would potatoes.
