So, I am doing a fairly unusual bonsai tree.
An avocado.
I planted him from seed about anywhere from 4-6 months ago, I can't quite remember when exactly I planted him.
But, he is growing extremely well he is within the range of 16"-18" tall now.
However, he is still green 100%, he isn't thick tan wood yet. Still very malleable and soft green.
So, I am wondering when I should start root / stem pruning.
Should I start stem pruning to make him smaller and fill out his lower layers?
And should I start root pruning when he is only 4-6 months old?
Thanks in advance.
