I worked with a nursery man for over ten years & we rooted lots of woody plants, some of them were brown figs.
I have never heard of or saw this happen.
I can not wait to tell my nursery friend, he is retired & 94 years young.
Good job & thank you for sharing.

It is not a rare occurrence in fig rooting when buds above the soil level fail and a bud below the soil level shoots up.
It also can happen that main stem bud above the soil shoots and also a secondary shoot comes out from beneath the soil level.

The same thing is happening to some of my mulberry cuttings.

you're rooting mulberry cuttings? good for you, I failed on those and given I never even got root initials forming, I gave up.

I'm also rooting white mulberry right now. I lost two rooted cutings to rot, and now after changing to a diferent metod I hope I'll get at least one good plant.
