I have two young Willow Leaf ficus and I would like to work on thickening up their trunks. They really have not been shaped yet. I have them in some potting soil at the moment in garden pots and just letting them grow out.
Good advise!You're on the right track. Letting it grow out without cutting anything should be the fastest way to thicken it up. Do you have any buds or branches down low near the base? I read a blog post where a guy chopped his ficus down to a little stick and let it grow for a year (in Florida). The plant out out a ton of buds and the extending growth fattened it up a ton:

I've been told that a ficus will fatten up at the base when put into a shallow pot and becoming root bound. I have a couple cuttings I've been developing for a couple years now and they seem to have pretty good bases after being developed in bonsai training pots. The trunks haven't thickened up almost at all though.
Here is an example of the swollen little ficus in tiny containers:

Alternatively you can grow them out a little more traditionally. Here is the advice I got from Adam Lavigne:
"Start with a six inch pot in good draining soil. Let it grow uninterrupted for a year. Move it to a gallon pot. Half full of soil. Grow half a year then cut it back. Grow until next year. Put it in a 3 gallon pot. Half full. Grow for a year.
This process will grow the tree tall and consequentially, fat.
The half full pot causes the tree to want to push up above the pot rim quicker and also the humidity and darkness will encourage aerial roots. The relatively shallow soil mass also encourages the root base to spread. It’s this process over and over. Year by year."
Can you post any pictures of your ficus?
When you read my post keep in mind I live in Florida, my trees are outdoors all year long, and I fertilize 4 times a year with 25-4-10 fertilizer.
