I thought I’d post an update on the pines from seed I started this spring. I never got around to making seedling cuttings this year, though interestingly enough Jonas from Bonsai Tonight decided to forgo cuttings this year as well.
I didn’t have the greatest success rate with the Japanese black pines from seed, as only 7 germinated. The JRP sprouted pretty strongly at 17. There are roots growing through the drainholes which to me is a good sign. I think next spring I’ll try potting some up individually and leaving some as they are for a few years. Trying to make sure what is left has a higher chance of survival.
