@justtryme90 thank you and congratulations with your lemon trees. I have manage to grow some lemon, tangerine, orange and blood orange but I didn't put them in the fridge, I didn't know it would actually work with them, too as those are tropical fruits.
I did peel their seeds off and just put them in the ground sometime in February and as fast as 2 weeks they germinated. It's a new information for me that stratification actually works with tropical seeds. Intrigued now.
