So explain this to me.  I’ve attempted growing parsnips this year in raised beds, and overall, it’s not been very successful as many of them have grown into deformed, mad-looking veg.  But not all – some have grown into perfectly acceptable parsnip-shaped parsnips!  Why is this?

Take these two photos – all these parsnips are from the same raised bed:

Two look like normal parsnips and the other two like extras from ‘Pirates of the Caribbean!’ I realise the soil was too rich for root veg, but I don’t understand why some have managed to grow normally.  Weird! 

Oh well, the up shot is, next year they are going back in the main veg plot where they’re happiest.
