Ten gallons is pretty small. I'd be putting that in a 25 gallon pot, or preferably in the ground.

The problem is that my garden soil is very poor and smelly idk why and can it live forever in that container

So if the container is the problem so do I ha e to put it in a 20 or 25 gallon container and what soil mix should I use when I transplant?

HU, it is not the container that make the figs bigger, a larger container such as a 25g will produce a larger Plant as the container will support a larger root system.

Some fig strains naturally have bigger figs while other fig types have smaller figs.

Think of mulberry fruit some types are naturally bigger than others.

You can experiment by pruning the ends of your fruiting branches and pruning any new shoot growth immediately from said branch to limit the fruit set and most likely the figs on branch may grow slightly larger but at the cost of less fruit to eat.

As for potting mix you will get many different answers to that question some make their own , at my age i prefer to buy name brand potting mixes such as Pro Mix and once in a while add lime and also fertilizer.

I grow my favorite variety RdB in 10 and 12 gal pots and they do OK. I believe they are a natural dwarf type. Oddly enough, the one in a 25 gal pot has hardly produced anything the last couple years.

Gred,

The ronde cultivar is not a dwarf variety from my experience growing different figs in containers throughout the years.

Have had several come and go either splitting trunks and or not coming back from dormancy.

Here is just 1 example i found on 1 of our disks from 2012 in its 3rd growing season mind you our area south suburbs near Chicago.

The problem is that I don’t know the type of fig since I forgot to ask the person I bought this tree from

The problem is that I don’t know the type of fig since I forgot to ask the person I bought this tree from .

Not a big deal if you like the fruit thats a good thing.

Root pruning and fertilizing a container fig is a must no matter what size container it is in no need to worry about its fruit size just its health overall .

What if I transplant to a 20 or 25 gallon then a year later I put it in the ground the reason for this is because my ground soil is very poor a d I’m trying to improve the soil with adding compost and animal feces

My soil isn’t great, either, But I’ve always had much better luck with things in the ground than in the pot. If and when you do plant it out, fill the hole back in only with the excavated soil. If you mix richer soil into the hole, the roots tend to stay in that area rather than moving out further.

If you can find Mary Lane Seedless and Borjosotte Gris, those are pretty big figs. Some are bigger, but I don't know their names.
