We are currently on holiday in a region where wild sea buckthorn is very common. We'd like to take some home to plant in our garden, kind of a living souvenir.
The typical method for propagating would be to dig out new shots that have emerged from the existing roots. But apart from it being forbidden or at least morally questionable I want to be sure I get a female plant and males and females grow quite intertwined here. So I'd like to take a few cuttings from select plants.
Various sources in the web suggest different methods, from rooting them in (the local) sandy soil to drawing roots in a jar of water, also some say to take wooden stems, other fresh green ones. Hm...
Now add to this my very limited equipment:
No rooting hormones (some sources say it's useless for sea buckthorn anyway), simply a knife, a few food containers that could stand in as planters and some small plastic bags (the sandwich-baggie-type) if really needed for a makeshift greenhouse. Plus I'm about 1000 km from home and whatever I do must withstand a 10 hours car trip, possibly more if we do a detour.
How would you proceed?
To clarify:
Yes, I know that sea buckthorn loves to spread, I already have a male for pollination and a suitable place to plant it and no, I don't want to go to a nursery, where's the fun in simply buying a pot?
