Conifers and trees with leaves I fertilize year-round, but only a little in winter. Trees with no leaves, no fertilizer (deciduous trees in winter).
Start with big tree or shohin both ok, but start with big tree better. Shohin styling more easy, big tree more work so better. Shohin no space to work so difficult.
Shohin very, very difficult. I direct shohin group now. Display is very important. First branch should be very low.
Seed bonsai is important. All bonsai start from seed in nature. If we don't make seed bonsai now, in future, 100 years, 200 years no bonsai.
Young customers don't always have money so seed bonsai good. Old customers have more money, can buy bonsai.
I always use cut paste.
I have no apprentice, but I want one. I only have a little famous trees. If you want to work famous trees, go to bigger nursery.
