Victoria Falls Reblooming Bearded Iris

Bearded iris rhizomes are simple to plant, but they have one rule that matters more than any other: do not bury them deep. Plant shallow, give them sun, and they will reward you for years.

Unboxing

• Open right away. Remove the rhizomes from the packaging and let them air out in a cool, shaded spot.
• Firm is normal. Rhizomes should feel solid; trimmed leaf fans and dry papery skin are expected and healthy.
• Plant within a week. If you must wait, store them dry and out of direct sun, never in a sealed bag.

Planting

1. Pick a sunny site. Choose a spot with at least six hours of sun and excellent drainage; iris rot in soggy ground.
2. Loosen the soil. Work the top 10-12 inches, mixing in compost or coarse grit if your soil holds water.
3. Build a ridge. Dig a shallow hole with a small mound of soil in the center and drape the roots down both sides.
4. Set it shallow. Position the rhizome so its top sits right at the soil surface, just barely visible, then firm the soil around the roots.
5. Space 24 inches apart. Point the leaf fan in the direction you want the clump to spread and water in well.

Watering

• Water at planting. Soak thoroughly once to settle the soil around the roots.
• Go light after that. Water about once a week during the first season only if rain is scarce.
• Ease off when established. Mature clumps are drought tolerant and prefer dry soil to wet feet.
• Support the rebloom. Give plants consistent moisture in late summer to encourage the second flush.

Feeding

• Feed twice a year. Apply a low-nitrogen fertilizer such as 5-10-10 in early spring and again right after the spring bloom.
• Keep it off the rhizome. Scatter fertilizer around the plant, not directly on top of it.
• Skip heavy mulch. Mulch piled over rhizomes traps moisture and invites rot; leave the tops exposed.

Pruning and Maintenance

• Snap off spent blooms. Remove faded flowers to keep the stalk tidy and push energy toward the rebloom.
• Cut stalks to the base. Once all buds on a stem finish, trim the flower stalk down close to the rhizome.
• Trim foliage in fall. Cut leaf fans back to 4-6 inches after frost and clear away debris to reduce pests.
• Divide every 3-4 years. Lift crowded clumps in mid to late summer, discard old woody centers, and replant the vigorous outer rhizomes.

How deep should I plant the iris rhizome?

Very shallow. The top of the rhizome should sit right at the soil surface so it is just visible, with the roots spread downward. Planting too deep is the most common reason bearded iris fail to bloom.

Will it really bloom twice in one year?

Victoria Falls is a reblooming variety. It flowers late spring into early summer, then produces a second flush in late summer to early fall. Reblooming is strongest on established clumps in zones with a long growing season, and consistent late-summer water and feeding help.

Are bearded iris deer and rabbit resistant?

Yes, generally. Deer and rabbits usually pass over bearded iris because of the taste of the foliage and rhizomes, making them a good choice for gardens with browsing pressure. No plant is completely deer proof in a hungry year.

Are iris safe around pets?

No. Iris rhizomes and foliage are toxic to dogs, cats, and horses if eaten and can cause drooling, vomiting, and stomach upset. Plant where curious pets are unlikely to dig.

Do I need to do anything special for winter?

Not much. Bearded iris are hardy to zone 4. Cut foliage back to 4-6 inches after frost, clear away dead leaves, and skip heavy mulch over the rhizomes. In zone 4 you can add a light layer of evergreen boughs after the ground freezes and remove it in early spring.

What will I receive when it ships?

You will receive a dormant bare rhizome with trimmed leaf fans, not a potted plant in bloom. This is the standard way bearded iris are shipped and it establishes quickly once planted.
