Hi! Pine can be a problem, as I know, pomegranate usually gives roots even in water (however might be a good idea to put some in water and some in soil). For pomegranate can take up to 1 month to give roots, pine for sure will take longer, and you will need some auxin to help it. Good luck!

I'll give a try to the pomegranate then. Thank you so much!

Rooting pomegranates in soil (with a slightly vented moisture tent) is easier than in water and would also be easier to transplant. However, if you are one of those stuck on rooting in water, plant out as soon as you get much root growth. Roots formed in water will be highly ineffective when eventually planted out. I've rooted many pomegranate cuttings in early spring, before bud break.

I'll keep that in mind. Thank you! Wish me luck.
