I up potted several 1 gallon plants that were in Root Pouch fabric pots to 3 gallon pots today. When I cut open the bag I noticed several things such as:
The roots didn't circle and were well branched.
The roots were very healthy.
The moisture in the pot was fairly equal. With plastic the bottom sometimes is very wet.
The roots were growing into the bag.
The root ball and soil came out cleanly but without tangled and circled roots.

I definitely liked what I saw and will continue using these bags although I will use the cheaper ones because I had to cut it open to transplant. They will help thwart overwatering and increase aeration to the roots.

Root pouch makes different grades, some for short term and will break down in a season for in ground planting, I don't know if those are the ones you're talking about or another version, maybe these can help reduce the cutting of bags for you?

I bought all three grades to try. The one pictured is the middle grade. The figs will outgrow the bags in 5 months or less and since they are going into a bigger pot I can't plant the bag. Definitely a believer in these bags. I will follow up at the end of the season on the 7,10, and 20 gallon bags.

Thank you for the pics. I'm using air pots for my 1-3 gallon trees and fabric pots for anything larger. They look great. Gives me confidence moving forward.

Have you given any thought to the 45 gallon bags?  I thought about it but I thought they would be difficult to move in the end, the 1 gallon worked well for me with results like yours so it was an interesting idea.

I use SmartPots for most all of my trees & plants.  Instead of cutting them open, I just peel the fabric off the rootball and am able to reuse the SmartPot.  It's probably more stress on the roots  than cutting the pot, but it saves some money and I haven't had any problems up-potting. Perhaps because it forms such a strong root system and the roots are getting air pruned at the fabric regularly, anyways?

I am use 1-3 Gallon air pots. 3 quart to one gallon rootmaker pots. So far I like them very much. I submerge the pot  in water and then let drain on another bucket to catch extra water. Yes at first the fine wash out of the post, when I pick them up out of the bucket of water. but I just refill when needed. After time this stops.  Both pots can be reused and seem very sturdy. The rootmaker pots are made here in the USA I think.    I will post later this fall as how the roots look.

Maybe you can reuse your cut pots. Maybe you can pin the cut sides.

Chivas- the biggest I am using is 25 gallon. Anything bigger will be too hard to move.

Figaro- I cut these open because I didn't want to damage the cuttings which were very rare. Plus these are Root Pouches which are much less expensive than smart pots.

Chilly- nice idea. I wish they had a Velcro seam.
