Jacaranda are all over where I live, they have gorgeous purple flowers in the spring, and they grow really fast so I decided to do try a clump style bonsai. The local nursery already had pre assembled clumps of saplings that we're braided together. I don't like how braids look after they are grown so I took the saplings apart and re-bound them.
I bought two, this is what they looked like when I bought it.
I took the knot off and unwound the braid.
I gently separated the saplings, gave them a mist, and cut some tap roots.
I then bundled them really tight at the bottom, and on one individual i also put a wire a couple inches above the bottom wire.
I then potted them in a compost, lava rock, and vermiculite mix.
I think these trees will explode this year. The tree in the background is a Jacaranda and it was cut a year and a half ago and has about 10 feet of new growth.
Saludos!
