I started them both off in peat pots last year as the bed they were to go in wasn't prepared in time.
The Beetroot was fine, but about 60% of the parsnips had forked. That could have been from the peat pots or the bed they went into, 'cos there are quite a few stones in it.
I'm doing the same this year 'cos they're going in a new bed which we haven't finished preparing just yet. ::) But this time I'm going to do the 'make a big hole & fill it with compost ' method. ;)
