Five Year Native Tree Challenge: parvae_arbores's Pinus Rigida (Pitch Pine)

[B-funk allstars]

Nice looking tree and congrats on keeping it alive. All three I collected in Feb with 1"+ trunks have died after looking healthy until late May. I was so careful to get more roots from the sandy soil this time, but I'm about ready to give up collecting any large PP. I'll try one last time with some 1/2" material this fall, but it seems like a waste of time given my success collecting other conifer species.

Not that I’m an expert on this subject of collecting. But I’ve read how Peter Chan uses Sphagnum moss to help with trees that have a sick root system, or a lack of roots to promote root growth. I also read about someone who collects yamadori all the time. Their mixture is pumice, spahgnum moss and pine bark. So maybe this could help your success rate if you haven’t already tried it.
