I live in a remote area in the Ozarks, the area was home to Jesse James and kin folks(still is).
We do most everything the cheapest way possible. Jesse's kin folks probably don't grow figs'but i do some.
Here is a sample of what i do.

Cool.  I'll all for cheap.  =)  

Nice trick. I have one that branched out really close to the soil, so I just heaped the soil over it, and voila, new fig tree.

Yes sir duck tape and a bottle , i use water bottle and duck tape nothing fancy needed.

Cool, Jules and I are distantly related to Jesse James through our paternal grandfather. Like 6th or 7th cousin twice removed.... Or something

Don't spread that around, James.  They already call me the crazy fig lady, next thing ya know they'll be calling me the crazy outlaw fig lady...lol.  =)

Nicely done Bob.   Have a MBVS doing nicely for you when we get together.

thank you for the idea.

I'm all for a cheap alternative . Thanks Bob!

Nice setup Bob...I notice that you have your potted trees burried several inches into the ground, and heavily mulched...the trees seem to like it...also I use a similar method for air layering, except the bottle is placed upside down with the wide end up giving easy access for watering, and the cap end down for good drainage...your trees look great...good luck.

I fill the bottom of the bottle with large pine bark for drainage and regular topsoil the rest,not to worry about too much water, it drain right through. In a previous threat all my large containers have 3/4 " holes towards the bottom for the roots to grow out into the soil,that helps with less watering during the summer months.Cut roots of for winter storage
