This is what i do and afterward i trim branches (canopy) some as well because less roots will support a smaller canopy and if not done risk later figs dropping because of that.

I slice some off top and bottom of rootball then cut out wedges as seen in pictures then slice outer part of wedge then backfill tight once it is back in container.

Bought the electric saw for 19.00 on sale years back and use wood pruning blades made for it ts much easier than a handsaw that was used in years prior.

Hope this gives you idea's.

Martin,

Thanks for posting your photos of root pruning. I never thought of taking out wedges of roots like you do....a brilliant idea!

Fritz after reading your post again in which you said at the end -The other just had lots of greenery and no output. just took them out
from cold storage and fertilized them. I see tiny bits of green at some
branches end.

Root pruning as shown is done when plant is dormant so if yours are awakening and fertilized as mentiond root pruning should be held off till next dormant season.

Darn the Luck ! ! !
