Cutting Back Iris After They Bloom

Should the ever-blooming iris be cut back at the same time as regular iris? If not, when should they be cut back?

Feeding Irises

What do I feed Irises? I've had these irises since we bought the house in 2002. I've divided them and replanted them in many locations. I was told to feed them Bone Meal in the fall (something I haven't done yet). Is this good for them and if so where do I get the bone meal? The color has faded over the years in the leaves. I think that's due to improper feeding, am I correct? I also want to re-do the flower bed where they are now. Can I dig them up now, fix the bed and replant them now?

Cut off dead blossoms and dead bloom stalks when the iris has stopped blossoming, but don't cut back the leaves until they begin to turn brown in the fall. The leaves are needed to produce next year's blooms. When you do cut, leave a fan shape about six inches long. Feed your irises a teaspoon of bone meal every fall and when you replant. You can feed again a month before they usually bloom if you like, but they are quite tolerant of just one feeding.get bone meal from Lowe's or where flowers are sold,I sug to move them after they bloom,for more info search for"how to grow irises",good luck.

What's the Name of This Iris?

Top down view of black and white iris. As you may know I'm starting a new iris bed in "The Path Garden". I saved this picture a few years ago and can't remember where I got it. Does anyone have this iris or know the name? I would love to have it added to the garden for next year. Thanks for any help ThriftyFun's family can provide.

I found something very similar to your photo though not exact, see it here: http://www.waysidegardens.com//p/40 ... 2009%2520Specific&utm_term=Iris/ or do a search for "World Premier Iris". I did a bit of searching to find this one. Wishing I could have found the exact one for you. Have a great day.

While the others are still not ready on that plant can I cut back just the top bloom and give it away?

What is Cutting Off the Blooms of My Iris?

I have bearded iris in a raised bed. The last two years, I find as the iris bud comes up nice and tall, something is clipping the stem, snapping it off with a nice clean cut. I find the blossom on the ground. Are birds doing this? How can I prevent this from happening. Last year, I lost about half my blossoms this way.

I have problems with squirrels in the apartment complex that I live in. They dig the dirt out of my flower pots and eat the roots. I really wish it wasn't against the law to shoot the little critters in town. But a neighbor guy got in trouble a couple years ago for shooting them with a pellet gun.

Cutting Back Iris After They Bloom

What will happen to my irises if I cut them way back, leaves and all, now that they are done blooming?

RE: Cutting Back Iris After They Bloom

I was always told that the leaves need to stay on the plants and to just let them wither. That the rhizome gets "food" from the leaves and that if you do cut the leaves off that you won't get as many blooms the next year. I believe it to be the same with daffodils and tulips, that if you cut off the foliage the bulbs won't get enough food and you won't get many blooms the next year.

My sister-in-law mows her daffodils every summer and they always come back nice and green the next year, but with very little flowers. I don't want to take any chances, I like the flowers too much! (07/10/2008)

RE: Cutting Back Iris After They Bloom

My sister has a day-lily business and she cuts the blades back called fans for shipment. It won't kill the plant, but may not produce next year depending on the size of the rhizome. This goes for irises as well.

I have irises in a permanent location and do not cut them back, but allow the leaves to die down and in the fall, clean up the dead blades. Always pick off the old blooms before going to seed so you can have more showy blossoms the following year.

Transplant extra rhizomes from the bed so you have space enough for growth when plants get too thick. (07/10/2008)

By Lorelei

RE: Cutting Back Iris After They Bloom

In most hardiness zones (yours included), Irises need to be cut back in late July or early August. This is also the time to thin and transplant the plants. Cut the fans back to where they are about 5-6 inches tall. This allows the leaves to continue to feed the roots but makes your garden look neater. Remove any spent or damaged leaves.

If you are transplanting any of the corms (root tubers), make sure that you check them for iris borers. Borers will leave small holes in the corms where they eat their way into the corm. Dispose of infected corms in the garbage, not your compost bin.

When dividing corms, cut the small "daughter" tubers away from the "mother" tuber with a sharp knife. Transplant into shallow trenches. Spread the roots out and cover lightly with soil. Irises do not like to be buried too deeply, they will not bloom if the corms are covered with too much dirt.

I hope this information helps. I've been doing this for twenty years, and I have a garden full of irises. So do my friends and neighbors to whom I have passed along plants over the years. Good luck and happy gardening! (07/11/2008)

Wait till the foliage dies, then cut them back. (07/12/2008)


Bearded Iris (Rare Treat)

This Bearded Iris is called RARE TREAT.

By Great Granny Vi

Bearded iris, Iris germanica, is a hardy, long-lived perennial that require a minimum of maintenance. The flowers have six petals; three upright petals (called standards) and three hanging petals (called falls). A fuzzy line or beard runs down the middle of each fall. Flowers come in many colors including blue, pink, purple, reddish, white, yellow, and bi-colors. Most bearded iris flower in the spring (April to June depending on cultivar), but some of the new cultivars re-flower in the summer and fall. The second flower display is not as showy as the spring display but last into the fall. Many re-blooming iris are fragrant... Source: North Carolina Cooperative Extension Service


Cutting Back Iris After They Bloom

My dwarf iris has finished blooming for the summer. The plant is a big sprawling mess. Can I cut it back now (June 12)?

Hardiness Zone: 5a

By Sally from Chicago, IL


RE: Cutting Back Iris After They Bloom

We can divide iris here in Southern Ca. during July/Aug into Sept. I haven't heard about "cutting them back". The normal thing is to dig up the rhizomes and cut the leaves into a fan shape, wash off the dirt and rinse the rhizomes in a 9 part water to1 part bleach solution. Let them dry/scar over for a few days before replanting. I assume that dwarf iris are treated in the same fashion. Good Luck. GG Vi (06/19/2010)

Fabulous. We have a few, but they didn't do a whole lot this year. I think it takes a few years. (06/16/2010)

RE: Bearded Iris (Rare Treat)

Anyone who features an iris gets my attention. My late dad used to raise them, divide bulbs, and share with friends in their church. He also would always have a large variety to put in their yearly "sale", adding funds for church activities. My folks lived on Camano Island, WA., And although they have both gone to be with the Lord, I miss them dearly.

Thanks for showing me a "picture" reminder of their lives. I have lived on the Gulf Coast for over 37 years now, and miss "home" to this day. Now we are looking at oil on our beaches, here in Theodore, AL. (06/23/2010)
