How do you take care of irises after they bloom?

After blooming is finished, cut flower stems down at their base. But do NOT trim iris leaves after they have finished blooming. Leaves carry on photosynthesis for next year's growth. Cut off brown tips—and cut the flowering stalk down to the rhizome to discourage rot.

Does Iris need sun or shade?

Siberian irises grow well in cool, wet conditions and, though they thrive in full sun, they can also tolerate some shade. Plant about 1 inch deep in full sun to part shade.

When can you cut back irises?

It usually takes several weeks for iris leaves to completely die back. By early fall, the leaves are usually ready to be cut back, according to the Utah State University Cooperative Extension. Leaves should be cut back to about 6 to 8 inches above the ground. Then, wait until after the first hard frost.

How do you take care of Iris indoors?

Tips for Growing Iris Plants Indoors

Water: Water sparingly until growth appears, then water enough to keep soil evenly moist. Soggy soil will cause bulbs to rot. Humidity: Average room (around 40% relative humidity). Temperature: After the cold treatment, cool to average 60-65°F/10-18°C.

Should I deadhead irises?

Deadheading, or removing the old flowers, keeps the plants attractive and allows the leaves to collect energy for healthy root formation instead of setting seeds. Some irises may bloom twice a year if you deadhead properly. Break off the individual flowers on each flowering stem after they finish blooming.

Should I soak iris bulbs before planting?

Soak rhizomes for 10 minutes, rinse well, and lay out to dry. It's OK to wait days or even weeks before planting, but sooner is better. As long as the iris is in a sunny spot where its rhizome can stay dry, all will be well.

How long can iris rhizomes stay out of the ground?

It will not damage the prepared rhizomes to remain out of the ground for two weeks. Select a planting location with good drainage that receives a minimum of 5 to 6 hours of sun every day or that is in full sun. Iris may be planted in a bed or as clumps between other plants.

When can I divide irises?

Divide at the right time of year, after flowering, when irises become dormant during late summer, reducing the chance of bacterial soft rot. Avoid dividing during winter when irises are trying to survive on stored energy in their rhizomes. Snip the leaf blades to about one third of their height.

Why do my irises fall over?

Iris also will fall over if they are growing in too much shade or if they have been over-fertilized with a high-nitrogen mix that will spur foliar growth at the expense of flower development. ... Wait until late July to carefully dig up the clump of rhizomes.
