How long to stratify Boston Ivy seeds?

Hi Everyone,

I'm just wondering how long you really need to stratify Boston Ivy seeds for before they'll germinate?
Several website say anything from 30 days to 6 months so just wanting to know if anyone has had success with shorter times?

 

I always found with seeds that needed stratifying, to chuck half in a clip lock bag with barely(I mean BARELY)damp vermiculite in the back of the fridge for about three weeks, the other half sow in a gritty compost(coarse sand and spent compost) in a clay pot and leave it outside, away from desiccating wind and nosy rodents.
Odds are some will germinate just fine without molly coddling
