Ficus cutting that is healthy but does not thrive
I started a ficus benjamina cutting two years ago. It was from a large, thriving mother plant and the cutting was pencil sized. It's rooted, it's healthy and I've had some leaf growth, but it's never gotten much bigger than the original cutting, even when using fertilizers after the roots were well established. When I re-potted about six months ago, the root system didn't seem very developed and were only located across the original cut. It was my first woody plant propagation and at the time, I had seen stuff on the internet that talked about cutting notches below the nodes on the woody stem that was going to be below the soil level, which would create a more extensive rooting network, which I did not do...I just went with the cut across the stem. I'm curious if I should try to do that now...repot the plant and in the process, cut notches below the nodes to establish additional roots and hopefully get more growth as a result. Does anyone have any suggestions for me? Thanks so much!!
