Hi Andrew,
this is what has always worked for me.
Yes if you see roots growing out of 1 gallon pot you can go to a 2 or 3 gallon pot.

Yes you can fertilize that particular plant
I keep it simple when it comes to fertilizing with good results by useing miracle grow 24.8.16 formula on box its one scoop > per gallon of water.

There are many fertilizers and the one above is what i use but im sure others work well also.

Hi Martin,
thanks a lot. I really apreciate your response. I will have to repot here very soon as the roots are really starting to come out the drainage holes and I don't want to break them..

Also, I apreciate the fert. tips. How often do you recommend feeding them?

Andrew

Andrew i dont do recommendations only show in pictures or speak of what works for me in my climate .
Dont want folks throwing there figs at me if something goes wrong with ones fig tree. ; )

I feed my plants weekly and sometimes more depending on the weather rain-heat. I stop all fert early Aug or even late July.
Best Luck
Martin
