I have a few little ficus that I have been growing from cuttings last year. The trunks are still very small, the biggest being as thick as a couple pencils. They have been growing well since I out them in actual pots, but I don’t think they’re ready for bigger pots yet. So in order to create a thicker base, or at least the illusion of a thicker base, I am trying to induce some aerial roots low on the trunk. I soaked some sphagnum moss and packed it against the base of the trunks, then covered with aluminum foil. Hopefully the moss will help some roots pop off the trunk.
Hopefully by the time I have to bring the ficus in for the winter they will have sprouted a few roots and I can remove the moss.
