Made a bunch of seedling cuttings today - Was wondering, what substrate others use for germinating pine? Sifted sand was a success this year. (media.kbin.social)

Don't have much experience germinating pine. That mix looks very coarse. Is it just sifted sand and aggregate?

Yes sir, just regular masonry/construction sand where all the smaller stuff is sifted out. I've been experimenting with different stuff over the years, this worked the best so far. I think it has something to do with how much air is in the mix.

I've already taken a lot of seedling cuttings from the tray, but a month ago it was absolutely full of trees.

Brilliant. They look very healthy. I'll have to give it a go this coming spring (I'm in Western Australia). Do you collect your seed?

I wish I could, but I don't have access to any good pines near me sadly. I usually just order online, plant a few 100 and keep the ones that thrive.

Mostly Japanese black pine and Scots pines, Mugo pine. I'm sure JBP would grow great in Australia. I'm in Scandinavia so I tend to stick to the more hardy pines.
