Beetroots can be prone to bolting, especially if forced or in very dry conditions. Oddly I have found Early Wonder, which is claimed to be resistant to bolting, bolts when planted early under fleece while cylindrical French ones donít.
It is claimed that French varieties mature more slowly, but this is not the case in my experience, so that does not really explain why they donít bolt. I have grown Carillon and Cylindra in the past but I am now onto Detroit, which has that lovely earthy flavour.
The seeds are large enough to plant individually, in fact this is true of all seeds if you take your time. The standard practice is to plant two at each ďstationĒ and thin one of them out. I reckon itís better to plant at half the spacing measurement and then when I remove one the others continue to grow: voila! no wasted seeds.
