You should cut the flower stalk but leave the leaves so the iris will rebloom next year.
Deadhead the flower unless you want the seeds. Every three years, you should thin the iris or it will stop blooming.
It is used to cut soft tissue.
They don't last long however.
Iris do not need covering in winter.
Iris that grow from a rhizome, such as the Bearded Iris, are divided in the winter months or early spring in climates that are warm temperate. Iris that grow from bulbs, such as the Dutch Iris, are dug and divided when the foliage has died off after flowering, or any time until regrowth starts again.Irises can be transplanted or divided in late summer. The reason for this is they are susceptible to bacterial soft rot and need the heat and dryness of late summer to prevent this. Also do not plant too deep or they will rot. The rhizome should be slightly exposed. Check for any soft spots on the rhizome. It could be soft rot or an iris borer, either way cut that part off of the rhizome with a sharp knife.You separate Iris flowers when they do not bloom. This means they are in a "bunch" and need to be separated in order to produce blooms, not foliage.In the fall.
Iris leaves should be trimmed back when they have brown tips. Cutting the flowering stalk to the rhizome will also discourage rot. The leaves usually don't need to be trimmed because they will carry on photosynthesis for next year's growth.
Yes, spring-blooming iris can be cut back after the bloom.Specifically, a well-cared iris generally does not need extensive pruning any more frequently than every three years. After the bloom, the plant needs to redirect and reprioritize life-sustaining activities into building reserves for fall and winter survival. In midsummer, a spring-bloomer then will be ready for eliminating unattractive, unhealthy above- and below-ground body parts which are damaged, decaying, diseased or dying.
The fall season is when you replant them. I don't do anything special - just cut the tops down to four or five inches.
You can start with "The Face of Deception," the first book in the Eve Duncan series by Iris Johansen, followed by the rest of the books in chronological order of publication for a more coherent reading experience.
Iris plants spread by root. In the spring you can see this by noticing that the iris is producing a ring of new sprouts rather than from the center as planted originally. If divided (cut ring into for equal sections and replant) once in awhile the iris will live as long as you want. Each section can be planted in a new location in the garden.
Yes, the blooms should be cut off iris plants.Specifically, the plant in question has to redirect energy and reprioritize life-sustaining activities into seed production and subsequent fall and winter survival patterns. A bloom which is not removed provides competition for the above-mentioned concerns. It also will attract unwelcome pests to the plant when it is vulnerably trying to ensure perpetuation of the species.
Cut off the spent flower stems and leave the leaves.
