Thank-you for the answers, am relieved to know I should be ok. I'll make the mix more 'airy' when it's time to up-pot.
Phil, to answer you I have to admit to another small faux pas. The first fig I got is a Celeste, very beautiful and leafy, maybe 10-12 inches tall. It came in a 4" pot and right away I replanted it in a maybe 15 gallon pot. I now know I should have took it up to that size in steps. The other 2, a Blk Mission, and a VDB are pretty much spriglets maybe 4-5 inches with a couple of leaves each, and I only re-potted them into gallon size pots.
Thanks,
bill o.
