A friend's mother in law gave me a (too big) bag of dried clusters of seed pods, each containing a large number of seeds from various hydrangeas that thrive in the cold of New England. I weeded out thorn brush and other wild plants from a 5 by 2.5 ft patch on the boundary between cleared and wild parts of my property, dug out all the roots from the very organic acidic soil, opened six of the clusters of pods and uniformly spread that vast number of seeds (far too many for that area) pressed them in slightly, then threw 1/16 in of inorganic soil on top to discourage whatever might find and eat the seeds.
I never had a hydrangea before, on the slim chance that I did any of that right and a tenth of them sprout next spring, how do I tell them apart from weeds? I didn't find any pictures of what they look like at that stage. If anything close to a tenth sprout I need to transplant them further apart very early. How do I guess below ground size from above ground size in the first few months, to know when I can't wait longer to transplant without excessive intertwining of roots?
