I have some seeds of Picea Abies, Pinus Sylvestris and Liquidambar, and i wish apply the seedling cuttings technique used in black japanese pine explained in this blog. Is it possible to use this technique on those species? What do you recommend me? I don’t have many seeds and i want to make sure not to lose them all. Thanks!
I’d guess that the Picea and the Pinus species would benefit from it. But in both cases it’s not absolutely necessary if you follow the other instructions in the BT#20 article. The more important component for radial root development is a large sacrifice branch or significant vigorous growth and a colander or double colander. I’m thinking the double colander has benefits at this point…keep going back and forth on that point.
As for the liquidambar - I’m guessing you’re wasting your time. The more logical thing to do would be to wait until it’s a bit larger, then girdle with wire just above the soil to make is swell and ground layer to start a radial root base.
Eric thank you very much for the information! I think I’ve understood. So in this case it would be better to plant the seeds in a tray, seedlings grow one year and then cut off each main root and then transplant them into individual pots? And then follow the techniques shown in BT # 20?
Thank you so much for answering. Greetings from Argentina.
The seedling cutting technique happens 4-8 weeks after the seedlings emerge in the first year. If you’re going to do it you have to do it very young.
For trees where you are not using a seedling cutting technique I would grow them, wire etc on a normal schedule using whatever method works best for you. The BT#20 article relates specifically to Japanese Black Pines, but some of the techniques can be adapted to other conifers like Picea and other Pinus. I don’t think the techniques would be relevant to liquidambar.
Thank you for the explanation, i appreciate it! I will try it out this spring and see how it goes! thank you very much Eric! Greetings!
