Happy Black Friday.

Yes, you are quite addicted, my friend. Either you are adding to the humor of it, you need some serious help, or maybe a bit of both. I've also felt the experience of seed shopping, and it feels a bit like collecting pokemon. Gotta catch'em all!

Maples, and some dogwoods, are native to where I live. They really need lots of icy cold every year, including to germinate. Maybe consider using stratification also on the dogwood. Do you have a frost season where you live? They need that to go into winter dormancy, to store sugars for the next growing season. The dogwoods have such a short lifespan and grow very slowly. Any sudden change to their climate, and they seem to die. I find them growing low in the forest under the shade of very tall conifers.
