I prefer the direct planting method, although some varieties work better in sphagnum moss first, and vice versa too. I sometimes do both. Yes, 2 to 4 weeks. It can tale longer with a bit of bad luck thrown in. I have also found that those figs with a long ripening season, meant for warmer climates, respond well to heat while rooting. Not all, but some do, so I use it. Any variety known to be hard to root may benefit from heat.
