Iris Growing Tips

Does Iris like 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.

Where do Irises grow best?

Irises will bloom best in full sun. They can tolerate as little as half a day of sun, but it's not ideal. Without enough light, they won't bloom. Bearded irises must not be shaded out by other plants; many do best in a special bed on their own.

Do Iris come back every year?

Elegant form and showy flowers in almost every shade imaginable make irises (Iris spp.) ... Irises grow from underground bulbs or fleshy roots called rhizomes and, with proper care, the National Gardening Association says they'll regrow season after season in zones 3 though 8, or even zone 10 in dry climates.

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.

Is Miracle Grow good for Iris?

Any even fertilizer is fine. You don't want to over-fertilize, because that causes a lot of leaf growth, which may encourage rot, but the fertilizer itself won't. Beardless iris tend to be heavier feeders, thus need more fertilizer, but all irises want a little fertilizer now and then! Miracle Grow is fine.

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.

What is the best time to 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.

Will irises grow under trees?

While most iris require full sun to thrive and produce their beautiful flowers, there are a few species that you can grow in the shade under trees or on the north side of the house.

How close together can you plant irises?

Iris are generally planted 12 to 24 inches apart. Close planting gives an immediate effect, but closely planted Iris will need to be thinned often.

What month do iris bloom?

A number of bearded varieties bloom from early spring to early summer. Among beardless irises, many varieties in the Spuria subgroup bloom from late spring to midsummer. Some Siberian iris (Iris sibirica) and Japanese iris (I. ensata) selections bloom from mid-spring to early summer.

Do irises spread?

Bearded Irises Grow from Rhizomes

Such plants also spread by rhizomes, and irises are no exception. While some rhizomatous plants, like bamboo, spread rapidly and even invasively, the iris spreads fairly gradually—one of its main virtues for gardeners. But, as iris rhizomes spread, they become crowded.
