Can these grow in containers or must be planted?

Hostas are not happy in the heat.

I wonder if these 24in pots would be good for permanent growth.

Do you cut down the iris after flowering? They turned yellow, not sure if they'll bounce back or not.
If cut back, do I move them so dirt stays dry until next year?

i do not cut back anything still green and alive. that is what provides energy to the bulb so it can grow again next year when spring comes around.

i've not grown these types of iris bulbs in containers of any size but i suspect they'll not really like the heat and super dry spells that can come along without there being a lot more thermal mass to help cushion the swings in temperature and dryness. take a few and poke them around some places that they won't get overgrown or grazed and they will probably do ok. they seem to be pretty indestructable here as long as they're not cut back too much all the time.

like many other bulbing plants they start regrowing for the next season when conditions are suitable which means in some cases they can start putting out new roots from the bulbs as soon as mid-to-late summer, but they'll wait out dry spells into the fall or even to the winter, but if it is really dry a shot of water in November might be a good idea.

So leave them be for winter? Okay.
Did start watering them more. Might of been the heat.

if you are going to transplant them the best time to do it is right after they've died back. the less water they get during their dormant stage the better.

some people lift their bulbs and put them in dry storage until replanting in the fall. i've done that when i've wanted to redo a garden but it really was a lot of work that i wanted to repeat it a bunch of times. nope. they can take care of themselves if left in the ground if the conditions are suitable.

Hmm. Gonna plant the others in the big barrel!
Should I put the iris in them, too?
