Harvest of Memories Reblooming Bearded Iris

Bearded iris rhizomes are simple to plant, but they have one firm rule: plant them shallow. Buried rhizomes rot and refuse to bloom, so keep the top just at or barely under the soil surface.

Unboxing

• Open right away. Remove the rhizomes from the packaging and let them air out in a cool, shaded spot.
• Expect firm, dormant roots. Rhizomes arrive with trimmed foliage and dry outer skin, which is normal and healthy.
• Plant within a week. If you must wait, store in a dry, well-ventilated place out of direct sun.

Planting

1. Choose sun. Pick a spot with at least 6 hours of direct sun; light afternoon shade is fine in hot southern zones.
2. Insist on drainage. Iris will not tolerate soggy ground, so amend heavy clay with compost or plant in a raised bed or berm.
3. Dig a shallow, wide hole. Create a small mound in the center and set the rhizome on top with roots fanned down the sides.
4. Keep the top exposed. Backfill so the top of the rhizome sits at or just below the soil surface, then firm gently.
5. Space 24 inches apart. This gives clumps room to expand and keeps air moving to prevent rot.
6. Water in once. Settle the soil with a thorough watering after planting.

Watering

• Water weekly at first. Keep soil lightly moist, not wet, for the first 4-6 weeks while roots establish.
• Ease off once established. Mature plants are drought tolerant and prefer to dry between waterings.
• Support the rebloom. Water during dry late-summer stretches to encourage the second flush of flowers.

Feeding

• Feed in early spring. Apply a low-nitrogen fertilizer such as 5-10-10 around the clump as growth begins.
• Feed again after spring bloom. A second light application fuels the late-season rebloom.
• Skip high nitrogen. Too much nitrogen produces soft growth and increases rot risk.

Pruning & Maintenance

• Snap off spent stalks. Cut flower stems near the base after blooming to redirect energy.
• Trim damaged leaves. Remove any yellowed or spotted foliage during the season; cut remaining foliage back to 6 inches after frost.
• Mulch lightly, not deeply. Keep mulch off the rhizome tops; use a loose winter cover in zones 4-5 and pull it back in spring.
• Divide every 3-4 years. Lift crowded clumps in late summer, discard soft centers, and replant firm rhizomes.

Will it really bloom twice in the first year?

Reblooming iris typically need a season to establish. Expect a spring bloom the first year and a more dependable late summer or early fall rebloom once the clump has settled in, usually by year two.

What size do the rhizomes ship at?

You receive #1 grade rhizomes, the top commercial size, with trimmed foliage and roots attached. They are shipped dormant and ready to plant.

Are bearded irises deer resistant?

Yes. Deer and rabbits generally leave bearded iris alone thanks to the bitter foliage and rhizomes, though no plant is completely browse proof.

Is this iris toxic to pets?

Iris rhizomes and leaves can cause stomach upset, drooling, or vomiting if chewed by dogs or cats. Plant where curious pets are unlikely to dig.

Can I grow it in a container?

Yes. Use a wide pot at least 12 inches deep with fast-draining mix and keep the rhizome top at the surface. In zones 4-5, move the container to an unheated garage or bury it for winter protection.

Why isn't my iris blooming?

The most common causes are rhizomes planted too deep, too much shade, overcrowding, or high-nitrogen fertilizer. Replant shallow in full sun and divide clumps every three to four years.
