No issue.

But I wouldn't put them into a 12" pot if this person is using standard potting mix.

Too much soil and not enough roots to use the water = constantly soggy soil and root rot.

Thank you Dave. She'll be using a 5:1:1 mix since she's coming over to my place to pot the plants. The roots are very well established, not yet root bound but some roots are making their way out the drainage hole. The pot is a standard 12" terracotta pot, the plants will take up the width of the pot and there won't be to much extra space for unnecessary soil.

Does she already have the pot? I'd try a 10" over the 12".

I think so. But I have a 10", so when she's here I'll try that out and see how it fits.

FWIW - a 12" pot with the same proportions as a 6" pot will hold about 8X as much soil as the 6". It hardly seems like that could be true, but if you run the math, that's what it comes out to.

Good luck - I hope you impress her. ;-)

That sounds like a nice combo, can't wait to see it!

If the soil itself won't cause the roots to rot, pot size is irrelevant unless it's too small. The bigger the better, IMVHO, as long as it doesn't make the plant look puny (but that would be a "eye of the beholder" issue.) If it's unglazed clay, the risk is reduced even further. I would choose the 12". If it's a plant that goes outside for summer, the bigger the pot, the less likely that it will be tipped over by wind.

I hope it will be a repot (where the old soil is removed & any really long/circling roots are trimmed) vs. a potting-up (where the undisturbed root ball is inserted, like a puzzle piece.)

Be ready to avoid the latex sap &/or wash it off quickly if contact is made with skin. Finding out you're one of the ones who gets a rash like poison ivy from it is no fun. Best luck!
