2020/21 - What's made you happy today?

Looks like most of my parsnips have germinated, I'm well pleased

Any advice on what size they should get to before thinning out please?

Not sure what others do but my final spacings are 6in between plants each way then I can dig them out without damaging the others.
   
A good tip don't know were I read it though is to pinch out the tops of seedling rather than pulling them up so you don't disturb the roots of the rest.
