>> Try pre-sprouting the pea seed in a tray,
Peas indoors? That's a new idea to me!
>> Do you use raised beds? They'd be warmer and you can control the type of soil.
Yes, exclusively, and I agree. But I've been expanding my beds faster than I buy compost, so the soil is still heavy.
I had thought of putting plastic film over my RBs, covering the walls also so their "feet" warmed up earlier. But mainly, to keep the constant rain out of the bed!
My Snow Peas finally warmed up and now they are yielding nicely for their size. Those bushy vines are going to triple the size of my next compost heap!
Is there any such thing as "pole" snow peas?
