Yeah, I would still like to hear of anyone who has tried planting in a root-pruning pot and could compare the performance to a standard pot.
I am a little concerned about my fig this year. It's happy enough and has several baby figs, but it has not branched out nearly as much as it did last year. I just don't see any more room for it to set fruit at this point, which would be a disappointment.
The difference between this year and last is that I drastically pruned the roots last year, and did not prune nearly as much this time (though still pruned at least 20%).
Maybe it will still do some vegetative growth and set more fruit but if it doesn't, I guess I've learned my lesson.
