Stratification of seeds

Hi I’m after advise on stratification of seeds can anyone share successes failures etc I have almond trees and I think when I harvest a few to set for seeds this is something I need to do but after browsing there are very different advice out there so wanted to come to the professionals to give me the best chance of success as I would like to germinate about fifty seeds thank you and look forward to any input you can share and also is this something that works with different types of plants to as I have small pomegranate that has split fruit so was going to harvest seed for that too

    Do you intend these to be productive trees or germinating just for fun? If you want productive trees I would buy some. You will find they have grafted the best variety to give you fruit in a reasonable time.
  • Hi yes I’ve got about 80-100 almond trees .....we harvest for almond flour and almond milk ....will want them to produce eventually and we are trying to live from land so time scale isn’t important really I just feel as I have trees that are reaching the end or dying from different causes I would like to replace them and I feel you get so much satisfaction from trying than buying ( crykes i sound like I’m on the good life lol ...) 
  • I have a pomegranate plant grown from a seed but cannot remember how I did it.. It is about 15 yrs old, never had a flower let alone fruit. Apparently pomegranates need lots of very high temperature which will explain my failure. Maybe with repotting and moving into my new recycled greenhouse it might help.
    Stratification is to break the tough seed coating. I used it to germinate some snail vine seeds which again worked well. Some plants need a spell of cold to kick start them into growing. I would think the RHS site would be helpful.

    Stratification is a process of encouraging seeds to germinate and can increase success rates.  Some won't until they've had a winter and feel it's safe to grow so you either need to sow them in pots and leave them outside for a winter or else mix them in with some compost in a plastic bag and put them in a fridge (not freezer) for a week or two and then bring them out to germinate and grow.
