Growing Thuja plicata from seeds
I've experimented quite a lot with growing various conifers from seeds - with very varying luck, and so far I haven't actually got any trees from it. Damping off being my worst enenmy, my poor memory probably the 2nd worst. But that said I must say it can require quite a lot of work and patience.
Anyway, I find it intriguing to grow conifers from seeds, but apart from http://www.sheffields.com/ I haven't found very many good resources on this on the web. Apart from all the initial "stuff" (scarification and stratification, correct soil, correct moisture, avoiding damping off etc.) it would be interesting with a way to see the expected time between sawing and germination, and also development along the way.
So now I am going to post here (new messages in this thread) regularly my progress with growing Thuja plicata from seeds. I hope it will be a usefull resource for others who want to try the same thing.
I received a small bag of Thuja plicata seeds from http://www.chilternseeds.com.
I immediately sowed 10 seeds in moist sowing soil (standard sowing soil from the local nursery). After 14 days none of these have germinated as yet.
Another 20 went for scarification, and of these 10 went for further stratification (at +5C in the fridge).
Of the 10 that were scarified but not stratified, 3 have germinated - this happened after 1 week. They are approx. 3 cm high, each have 2 cotyledons and they are struggeling to shed the seed-cap.
They are emitting a quite strong smell like the foliage of Thuja in general. Assume this will help me fight off rot and fungi.
