If I store my seed in the shed over winter, do I risk killing them off? They will be very dry but extremely cold - down to -25°C outdoors, probably -15°C inside the shed.....
Does anybody know whether seeds will suffer from such cold temperatures?
Or is it a better bet to keep them in the cellar where they rarely go below +10°C but may be a bit of humidity?
Thanks!
Surely if they're dormant they'd be fine as long as not damp? Though, sorry Dan, really not sure...but they'll be someone who is!! And cor blimey that's cold!!
Lottie ;D
I thinkk you'd be best off keping them in the shed, I'm sure that it's better to be dry and cold than warmer but humid. I think that some seed banks freeze seeds, and I keep mine in the fridge, most to OHs annoyance ;D
With winter lows below yours I can attest that they will be unaffected by your climate- each summer I regularly get volunteer tomato seedlings from the previous years' outdoor crop. At +10oC and some humidity there could well be an adverse affect on the germination % due to seed deterioration. What you may have to prevent though is attacks by rodents in your shed!
