Fig tree or bush

i bought a very small fig plant back in the spring, I was warned to not plant it in the garden unless I sow it in a washing machine drum to prevent it from putting all its energy into roots instead of fruit. So I planted it in a planter that I can moved inside the tunnel in the winter.
I was very surprised last week to find some babies.     
Some people have told me to plant it in one of the raised beds in the tunnel and leave it in there all year round.
Any suggestions from experience???

There was a fig planted in a greenhouse boarder in one of the house we rented for a short time. It seemed very happy in there. But that’s as far as my knowledge goes.
Well done on having babies already.!

From experience, don't plant it anywhere unless its roots are contained! Its a thug - like Kiwis.
I started with 2 fig tree cuttings that I planted in a <12" wide bed between my drive wall and the neighbours garden. Its now an impenetrable fence, so high that my neighbour has to prune the top of it. I suspect that the roots are also in his garden (which is uphill from mine).

I planted mine in the border despite reading all the advice. It hasn't got that big, I suspect it gets too cold when we get frosts as I'm in a frost pocket. I've had figs once or twice, they were delicious. The small fruits need to hang on over winter and that's my downfall, they get frosted off.

I like my GH space so Im not sure I would want it in the GH - depends what you like to grow I suppose. Im sure it would love it in there.

The IOW has figs growing everywhere and some are massive trees, I think its the frost free southern coast weather that let's them run rampant, so poly would be ideal climate but not sure about pollination.

As long as we have a mild few weeks, some of the larger ones look like they should ripen before winter, particularly if you move it inside.
