@drdawg,
Thanks for getting back to me. I will try making a soap for the pests in the soil - the internet suggests a solution with Dr. Bronners soap, so I will give that a go.
As for how I am growing this plant --
When I acquired the tree, it was potted in a 10-gallon plastic pot, and I repotted it to a 25 gallon stoneware planter. I keep it in the shop, which has northern exposure, with high floor-to-ceiling windows that let in plenty of natural Southern California sunlight. I have heard that fiddle leaf figs do not enjoy direct sunlight, as it may burn their leaves. The level of light in the shop has supported healthy and rapid growth for our other plants - a ficus benjimina, monstera, bird of paradise, umbrella plant, rubber plant, several dracaena, and a kentia palm. I water the tree once the top inch of soil is dry from previous waterings, and wipe down the leaves once a week to prevent the plant from "choking." I fertilize it occasionally with an indoor plant solution that mixes in with water. Again, the little guy doesn't seem to be unhealthy per se, just doesn't seem to resemble others (where the leaves point down) and doesn't seem to be producing any new growth. It is a little over 6ft tall.
Thanks in advance for your guidance,
Amanda
