Thanks everyone!
My goalis to find the species that do the best on my property with the least amount of work. So, this year I started batches from seed of what seem to be the most popular species, and some 1 year old seedlings that I purchased.
Growing these seedlings and doing simple wiring, some seedling cuttings, different soils and pots etc is just as interesting to me as the artistic side of actual bonsai trees.
I want to see "what can I easily grow, that is not worrisome, that doesn't need more than the cold frame set up I already have? (Which I think will cover most)"
"What species, soil, placement, pots will allow me to miss some waterings?"
Then to grow my knowledge slowly along with the seedlings, without fear and pressure.
I will develop a small modest collection based on those findings. I don't even expect to show them (Though I still want to do the best I can for my own enjoyment.)
I will probably sell some two or 3 year old seedlings as I learn what works best for me. So I am growing "desirable"species like European beech, Korean hornbeam, trident maple, Japanese black pine, ginko, bald cypress, larch, hemlock etc so they are not worthless if I don't choose to keep them.
I just want to make a batch of vanilla brooms. So I have these Chinese elms that are about 2 yo and only 1 zelkova that I grew from a seed last spring. I love the full grown zelkovas around here, but by desirable I suppose I meant easiness to develop, and monetary value if I decide to sell.
I have enough Chinese elms to propagate to my hearts content, but I am wondering if it would be worth starting zelkova seeds or buying starters.
Sorry for long post.
