Hi, apologies if this is a stupid question 
I thought I’d get organised by ordering all the seeds I need for my veg patch this year. Work is unpredictable and if things get busy in the next few weeks I know I won’t have the mental energy left to decide what to plant and where. Not to mention pick up the various items I’ll need (I’m still relatively new to this).
Anyway! I was notified last Thursday that my order had been dispatched. I was supposed to receive it yesterday but didn’t, as all the snow we’ve had here has caused a lot of disruption. I’m just wondering whether the seeds risk being damaged during transit if they’re exposed to very cold temperatures?
