bolting carrots.

I had something similar last year with some Spanish Black carrots - bolting and very woody thin white roots. I was worried, like you, that the whole lot would go the same way. In the end, I pulled out the 'bolted' ones but left the others going and they turned out well. I thought in my case that it could have been to do with sowing the seed too closely (I scattered rather than sowed in rows). Another possibility is that Spanish Black are not F1 hybrid and it could be that some of the seed was not 'proper' Spanish Black. I don't know if that might apply to you as well.

In any case, if I were you, I'd give the ground a good soaking and pull out the bolted ones as and when they appear and let the rest carry on.

If carrots bolt it is usually the fault of the seed producer. Often there are one or two which can be weeded out.

Thanks, sounds like the weather conditions we have had here.
