I'll just mention what I do for the entire process. I use the baggie method and stratify rose seeds at a temperature of 2 to 5 C (35 to 40 F) and generally in about two months germination has begun. I carefully pluck the sprouted seedlings from the bag and plant them into an organic mix that contains no compost or fertilizer, I have also used ProMix with good results. Seedlings are very fragile and must be tented for the first while, if they wilt and dry out or overheat, often it's the end of them ... also, be very careful of over watering! Last year, I had tons of early germinations in November and seedlings developed very well during winter while sitting in a cool sunny south window, I ended up with nice stocky plants! Many folks also choose to grow them warmer and under lights, I don't have any experience with this, though avoid frying them with intense light or heat.

The reason I do the baggie method is that many seeds will stay dormant and require a second or even third round of cold stratification to wake them up. So, removing those that have sprouted will give the rest a chance to germinate in their own time. If all seeds are sown in a pot at the same time, those that remain sleeping will likely never get a chance. This might be okay for some, though because I do hybridization, I want to give all potential seedlings a chance.

I leave mine in the refrigerator until they sprout.

Thank you both! I didn’t realize they would sprout in the fridge :) I’ll be happily waiting for them to sprout !
