I previously bought a "beginner bonsai kit" off Amazon that came with 3 guages of copper wire. I think 1 millimeter 2 mil and 3 mil. Those lasted me about 3 years. This year I have a lot of young seedlings from this years crop that are ready to wire and to save some $ I'm wanting to get some aluminum wire. Wondering what's the best gauge of aluminum wire for seedlings. Mostly Japanese maple, some trident, and some Chinese elm.
