i bought acer rubrum seeds from sheffields.com in may 1st. I soaked them for 24 hrs, drained, and put all of them in a moist paper towel inside a freezer bag. I put the bag in the back of the fridge and its been 21 days and no signs of germination. the seeds are not dead because i cracked one open and it was completely green inside, with everything intact. I soaked them again in cold water for 12 hrs yesterday, drained them today, and put them in moist potting soil in a sandwich box with the lid on in the back of the fridge. what should i do? how do i deal with dry red maple seeds?


the site i bought them for is reputable

Stratification of maples takes 60 to 90 days. Put in slightly damp peat moss or coco fiber in a dark place inside the fridge for 2 to 3 months, then remove them from the fridge and pot them up. Put them in a warm place with bright light. They will not germinate in the fridge. You may end up having to grow them indoors through the first winter starting them this late unless you are in a frost free area.
