Over the years I have taken many hundreds of cuttings. Most Ficus can be started easily from cuttings and even large size cuttings can be rooted with success.
Ficus cutting about 8-9 years ago
This is a Ficus microcarpa cutting taken from one of my very large bonsai.
It was allowed to grow without trimming to recover strength and over time branches were selected to keep, other branches were removed and other branches were grafted into areas needing a branch. The bonsai after 9 years of training. Still not completed but it has come a long way from the start.
Years later the same cutting is beginning to be an attractive bonsai
Consider rooting your extra cuttings to use for future bonsai.
