Is it just me, or is a bad year for spring germination

The soil is still quite cold.

If you look at other threads, you will see that poor germination does seem to be a common problem this year

Mixed for me.  Some things have been great, carrots and peas are 100%.   Beetroot and salsify are rubbish though.   No sign of parsnips yet, but only sown a week ago.

I start most things in the heated propagator  at home, pot them on in little paper pots, then hand over to Mr Bee for the allotment. He like straight lines and I do higgledy piggledy.

The only thing I have started from seed are salads, carrots and spring onions. I think the soil in the raised beds is warmer and so  haven't noticed a problem so far with germination. Touch wood.

However why is it too cool for seeds to germinate but not too cold for the *****y weeds.
