I had hundreds of iris, my husband sprayed weed killer and very few of the iris came up. Did the weed killer kill all my iris? Or is there any chance of them coming back?
I would investigate the type of weed killer used.
Most herbicides will kill perennials and it sounds like that is the case in your Iris bed.

You can wait and see and salvage any Iris that do survive.
My rhizomes dont have any roots. Can I still plant them or should I put them in water to grow some roots first?
Direct plant them, do not soak in water.

It appears that many of my irises have changed color since last year. Is this typical? I have been growing these same plants for 20 years and have not experienced this phenomenon previously. Can you suggest why they have changed? Thank you, David Womelsdorf

When my Siberian irises bloom the flowers are halfway down inside the leaves. Why does it do that?
Lack of sunlight can be a cause of stunted growth as well as soil, water, nutrients and pests and insects.
Stunted growth could also be a sign that your plants should be divided.

My houseplant looks like an iris. It produces several blooms each on many long stems that hang down almost to the floor (the plant is on a table). The blooms are white and purple with yellow centers, are small and looks like an iris. any ideas of what it is? And thank you. Andrea
You have an Orchid! The type I'm unclear, but you may be able to research it.

I've been given several Bearded Iris that were just dug up after blooming.. They have been trimmed to 10 inch fans.. Do they need fertilizer? I haven't trimmed mine back..thought it was a little early? What do you suggest? I've put them in planters for the time being. Thank you
Iris are often transplanted after flowering. 10" fans are very generous, maybe too tall to withstand a storm while the roots are getting established. Prepare a wide circle for the iris and use soil to make a mound in the middle, a little flat-topped volcano. Place the iris on the mound and spread the roots out. Refill the hold and water. The rhizome should be half exposed after planting. Don't fertilize until you see new leaf growth and then go with half the recommended rate. As with other bloomers, the leaves help rebuild the plant's energy after flowering. Unlike tulips, iris leaves are present all summer and fall so trimming them now is OK for transplanting.
About 2 years ago we planted over 100 dutch iris bulbs in about a 60' area next to my garage by our fire pit, facing east. Many of the flowers poke through every year, but never get more than about 10 inches tall. Several have very small flowers bloom, but nothing like I was expecting. Are the flowers still trying to get established, or am I doing something wrong. Could they be getting too much water
Dutch iris are often treated as annuals. After one blooms, the main bulb is done blooming but lives on to nourish bulblets. These baby bulbs take several years to reach blooming size. Here is more information: https://www.longfield-gardens.com/article/All-About-Dutch-Iris
