The white pine seeds I sowed last month have only sprouted four seedlings. I was hoping for a better sprouting rate than 20%. At least it’s better than the Korean Hornbeam seeds I sowed, which had a very sad 0%. The seedlings are now at a size that can be made into seedling cuttings.
The usual treatment applies to these seedlings as before. I first cut the trunk to 1.5cm long, dip it into a gel form rooting hormone, plant it into each individual pot, then finally secure the soil around each seedling cutting.
