Has anyone tried seedling cutting on any pine species other then JBP? I've had good success cutting my JBP seedlings and I have a few Jeffery and Coulter pine seedlings coming up I would like to try it on.

I find it hard to believe that this method would be exclusive to JBPs but I'd rather not just cut my seedlings up for nothing.

any experiences would be appreciated.

I have not tried, but woudl recommend you try it on a few seedlings. Curious to hear the outcome. I agree with you, that it is likely others would also work.

Ok I gave it a try on a Pinus jeffreyi and a Pinus coulteri seedling. I'll post an update if it takes roots or not. I did the same technique that I've had success with JBPs. Soak the cut seedlings in root hormone water 30 mins and place in akadama surrounded by pumice. Cover with a humidity lid and place on a seedling heat mat.

Well the good news is that the seedling cutting for Jeffrey Pine (Pinus jeffreyi) works. The bad news is I was a bit too aggressive with checking for resistance and snapped the root off. I've started a few more since this one so I'll be more careful next time. I did this cutting in Mid March 2023.

The seedling cutting for the coulter pine (Pinus coulteri) I also did in March was completely rotten when I checked on it today. That doesn't mean it wont work for coulter pine this one just happened to fail.
