Advice for pretreatment and stratification of Japanese Cedar

OK, so, I've looked around on various sites and the general advice for these is 24 hours in water, then stick them in the fridge for about 4 weeks, in damp soil.

Would anyone else suggest differently or does this sound about right? 
Also, I read somewhere that any seeds you have that float in the pretreatment are probably empty husks that won't grow, is this right, or is there a chance they'll grow anyway? 


  • Yea, that's where I looked already, just asking if anyone here has any other tips, plus the thing about floating seeds?

    Floating seeds are not viable as a rule, nothing there so no weight.
    I never faff around, I sow seeds in gritty compost and leave them outside somewhere sheltered til they germinate, often in spring. Once the cold weather starts I put them in a cold GH so I can see when they germinate and nothing eats the tops off

  • Thanks, might as well scoop out the floating ones and discard then. Yea, as much as I'd love to try a more natural approach, I live in a 1st floor flat and have neither a balcony nor a personal garden, so that's not an option. That's why I gotta go through the stratification approach so I can has me some nice indoor plants to liven the place up a little.

  • I'm gonna be keeping it as a small bonsai. :smiley: not gonna have a 10ft tree in my living room.

    Should be perfect for that then. I like Bonsai,  especially the ones with blossom,  although a friend mine keeps them and keeps them outside.

  • Most traditional bonsai are outdoor plants. A cedar is a cedar however big or small you grow it and it will not be happy with indoor conditions. 😔 

    You will have far more success at growing plants if you assess the conditions you can provide and research the types of plants that will thrive in those conditions.

  • Yes mate, I know it'll be happier outside, most, if not all plants will be, but with the right care can still be nurtured inside. Which is what I'm hoping to do. Granted, I may not manage, but it doesn't mean I cant try and have to just give up. If it doesn't work out I'll try one of the other varieties of seed I have. And keep trying till I'm successful.
