So, I have been at this for just a year and a half, and pretty much wasted last spring because I had very little material, got tons of cool material (non-masterpiece pre bonsai still in soil but with little root treatment and some reduction). Importing trees is illegal here.
Right now my goals are (now to 5 years):
1. Get trees into pots and make them mediocre-decent bonsai.
2. Start planning longer term projects (the lack of variety here makes me have to start some things from seed).
3. Learn how to wire.
4. Learn how to graft.
Medium Term 5-15 years:
1. Have really nice looking trees, hopefully over 10. (couple pines, deshojo, regular palmatum, palmatum forest, smoke style sumo trident, ror trident, a chuhin sized azalea, shohin sized azalea, shimpaku, wisteria, olive, couple elms)
2. No need for shows, because we basically have just a few but have them presented really nice at my house.
3. Get really good at transforming nursery azaleas into nice bonsais.
Long Term:
1. Hope my kids want to inherit my bonsais after I am gone.
2. Get at least one person to incoporate bonsai in his/her life.
