Q. Japanese iris blooms

Should the stems of Japanese iris blooms be cut following the bloom or should they remain to form a seed pod? I am unsure of what to do as far as pruning after my Japanese iris blooms. I generally allow it to form seed pods and don’t cut down the entire plant until early spring. It has bloomed beautifully for 8 years and I do divide the mother plant every other year. Is that all there is to it?

Most people cut the flower stem after blooming to prevent the plant from expending energy on seed production. You don't need the seeds unless you want to go into iris hybridizing. Japanese iris are pretty easy, as you've found. Check out this article for more pointers: https://www.gardeningknowhow.com/ornamental/bulbs/iris/growing-japanese-iris-plants.htm

Q. Why aren’t my Japanese irises not blooming

I have a large bed of Japanese irises with wonderful leaves – close to 5 feet tall, but maybe 3 blooms a year. They are planted in a very wet area, and get quite a lot of sun. Why don’t they bloom?

Lack of flowers could be soil ph issues or most likely your plants need to be divided.

Japanese Iris are summer blooming plants. Flowers can last days to weeks, depending on varieties and weather conditions.

Q. Japanese Iris

My Japanese Iris flowered beautifully the first two years. The next year it had a long thin stem with very small bead like ovals. I sought some advice and so I separated the bulbs and put them in single pots of earth, sand and diluted vinegar. I have kept them moist but the same thing happened. Could you please help as they are beautiful and one that I had never seen before. I am attaching 2 photos. One of the flower and the other of the thin stems. Looking forward to hearing from you.

It looks like what happened is that a different plant has invaded your area. You may have propagated the invader by mistake. They have a growth pattern more similar to that of Daylillies rather than irises. Irises will grow from a layered rhizome resembling a hand with fingers. If what you planted was a true bulb, then this would be a different plant.
