Seed Stratification

JasyanJune 5, 2013

Hi,

I've read a lot on seed stratification but one thing I haven't been able to find is whether or not seeds that are stratifying (I use the baggie method with a moist paper towel) actually germinate while they're in the fridge?

I've been stratifying various raspberry and blackberry varieties, some with a moist paper towel and some with soil, and I don't know if I should be looking out for seedlings during stratification or if I need to plant the seeds after the stratification period for them to germinate.

I've also got some pear and apple seeds (I know they won't be true to type but I wanted to grow them anyway for fun) and they've been stratifying for over a month now and haven't done anything. Should I take them out after stratification and treat them like any other seeds that doesn't require pre-treatment? Or should I leave them in the fridge for a while longer?

I appreciate any help you can give me!

Seeds being stratified should not germinate at the low temperatures required for stratifying. When the time required for stratifying has been met, the seeds should be immediately planted. If not done, the seeds are likely to germinate when germination temperatures are reached, and then die. Al

As Calistoga said.
But if you want to test for germination after you pull them from the frig use the damp towel method in a close container outside the frig. Check daily but use a germination guide to understand the typical time to germination for that specific seed. These are only guides. I have seen seeds germinate quicker if in a warm moist environment.
