Q. How do I deadhead flag iris after flowering?

I have flag iris in my pond and want to know whether I cut down the main flowering stem or just pull off the dead flowers and leave everything else intact?

I deadhead the flowers as they fade. Then when all the flowers on the stem have been spent you can cut the stem from the plant.

Q. flag iris

I planted yellow and blue wild Flag iris around my pond. I have a lot of yellow this year but no blue. Is it possible that, like a hydrangea, the flag iris can change color due to the soil conditions?

I don't think that is the case here. Irises can fade over time but they will always have a general hue of their original color. I've attached a link with more info on irises.

Q. Yellow flag water iris

Can you remove the pods on the plants after flowering to start iris in another location?

A.

Yes, Yellow Flag Iris can be grown from seed. Collect the pods produced after the flowers wilt. The seeds must be exposed to cold temperatures before germinating, known as cold stratification. Place them in damp paper towels, roll up in a plastic bag, and store in the fridge for 3 months or until they germinate. When ready, plant in a pot, then in spring transplant outdoors.

Be aware that this plant spreads aggressively. Here is more about this plant:
