The progress on this tree is amazing and makes me super excited to see how mine turns out, I collected it in august this year and it’s taken to its pot very well. It was less than a year old I believe before I picked it up as I hadn’t seen it the year before. I’ve also dived into growing bonsais from seed, I’ve successfully sprouted a wisteria floribunda specimen about 2 weeks after I collected my boxelder baby. They’re about the same size now and the wisteria has known nothing but the pot it’s in.
I’m also working on sprouting acorns for oak trees cuz an oak in the neighborhood was definitely in its mast year and I couldn’t resist picking them up as I walked by. I’m in the bonsai journey for the long haul and don’t mind it taking over 10 years to get beautiful results from these trees. It’s only been 4 years since you’ve collected yours and look at how beautiful it is.
