Fignut uses a fig trailer, very nice design. I would build a small 4 by8 small frame with wheels and mount a plywood sheet on it. You can wheel it in and out of the garage.

Jim,
you said 60 plus fig plants that you store in garage, 4x8 with wheels is a start but your going to need something bigger. I have a 4x8 model train layout and looking at it doubt i could fit 60 3 gallon pots on it , and with pots bigger well you can see . Great idea from the above poster just go bigger and use straight trailer axles with wheels and figure out the squarre footage you will need. I would build one for me and pull with garden tractor i just dont have the room.

tbucketer, The link below shows the figmobile. It isn't very big, but is easy to manuever and will carry heavy loads. The grocery cart undercarriage is able to support a lot of weight, and turns on a dime. You have to be careful with weight distribution and support for overhanging platform areas, though.
I have made figmobiles with attached casters also. If you go that route make sure that both the "front" and "back" casters rotate and are not fixed as the back ones are on a shopping cart.
I've tried 4x4 figmobiles. They are more difficult to move (heavy), maneuver, and store. The narrow long ones (about 29-30 inches wide and 5 1/2 - 6 feet long) slip easily into small areas.
I often stack smaller figs on top of bigger ones. If you've got a strong frame, the limit seems to be how much you can pull.

Here is a link that might be useful: Figmobile

Hey it would be nice if you had a conveyor belt :)

Conveyor belt indeed !
Really though if i had my way and did not have that other car in garage i would make something like a 15x8 and put mine on there and move out with garden tractor and at night back it right into the garage. I denfintely would need something big like that cause of the size of containers i use.

Martin, A friend who has his fig in a bigger pot than yours has a dolly under it. He pulls it in and out with very little effort and very quickly. Anything that has to be hitched to something else to pull it would require more time just fiddling with equipment.

I use a cheap (~$20, avail @ HD, Lowes) not sure what
to call it; I guess "trolley"?
Long curved back and handle, 2 wheels, short bottom base.
You tilt the pot, shove the 'short base' of the trolley
under the pot, tilt everything towards you, and trasport.

Fignut, yes thats uderstandable,you should see me wobble em onto cobble stone walk way into yard onto patio with that hand truck it sure is an adventure.
Gorgi that sounds good, perhaps one day i could get neighbor to weld some curved steel onto hand truck to better stable to pot.
One day i move to nice climate me and the misses as she says now when children are up and out of house we leave, so im thinkning nice and warm cklimate and i grow mine in ground for good and no more of this moving them!

80 degrees today in Georgia, Martin.

Scott,
yes Georgia on my mind like the song.
When i used to visit Dad I drove thru Georgia and its a beautiful state, and the Misses did mention that as well about the move 1 day.
Darn 80?
We are having a high tomorrow of 33 after a 58 today.

A better description of my (cheap) fig transport device
is a "hand-truck" (2 wheeler).
Looking closely at the post 6 pic, by Martin; now I do see
one at the extreme left of pic...

I think I have solved my problem. Many of my figs are still small. I purchased a wire shelving unit from Target last night for $49. It is 72" tall, 48" wide and the shelves are 18" deep. It has 5 adjustable shelves that hold up to 350 lbs each(!). Once I add some big caster wheels, I think it will work out pretty good. It will also allow me to "stack" my figs and not take up so much room in the garage. I'll post some pictures once I get it all set up.

Thanks for your ideas!

Another yet (impossible) option:
"Beam me up Scott" technology.

Those are really nice units. I got the same size to put in front of a window to start cuttings, but only used four of the five shelves to allow more shelf height.
I don't know if it can be done, but if you can put the shelves on upside down, you'll have a "lip" to keep the pots from sliding when moving the unit.
Let us know how it works out, I really like the idea of using vertical space to "stack" the figs in the garage.

Perfect transport device 6' 16y/o son. Does not come cheap though, can eat $20 worth of groceries a day and requires clothing, shoes and sporting goods replacement on a continuing basis.

There may be a 4 to 6 weeks of duration between start of dormancy break and frost free date. Why not just provide good flourescent lighting inside the garage. The low inside temperatures will delay growth but the lighting will help avoid spindly growth durung this period until frost free date. The plants will require hardening later but it may save a lot of worries and labour taking pots in and out. Just a thought (with no experience to back it up)...

Ottawan in my case is being hardheaded i suppose, i just move onto driveway for full day sun when temps alow and back in a night. I dont have a problem with spinley growth, maybe cause of my zone but it does not occur. What my trees do is the buds slowly turn green and open then leaves start to emerge, ususally around that time they go on patio.

But what do you do when you have to move the plant over rough terrain? Little flat dollies have a hard time going over stairs and thresholds, etc. I've lived the lifestyle for many years of constantly moving huge potted plants to and fro. I've tried everything. I found these two plant movers from Nursery Enterprises I've used the bigger one for years. It's allowed me alone to do the work of a team of men--all without damaging my back or my expensive pots.
