Where do Irises grow best?
Irises are hardy, easy to grow plants with attractive foliage and spectacular flowers - good for every garden design. These flowers need at least a half day of sun and thrive in most climates. In extremely hot climates, some shade is more beneficial, however, irises do better with at least 6 hours of full sun a day. Iris should be planted so the tops of the rhizomes are exposed and the roots are spread out facing downward in the soil.
When should irises be cut back?
By early fall, iris leaves are usually ready to be cut back to about 6 to 8 inches above the ground. Then, wait until after the first hard frost. .
How do I take care of Iris bulbs?
No matter the variety you choose to grow, there are a few things you can do to help your irises thrive in your garden. Follow these tips below for the healthiest blooms. .
Plant irises in a sunny spot in late summer The plants need well-drained soil and at least six hours of sunlight per day. A full day of sun is even better to keep the rhizomes dry.
Prepare iris beds. Use a low-nitrogen fertilizer and apply it twice a year: In early spring and just after bloom when the rhizomes are forming the next year's flowers. Only water if it's extremely dry or after transplanting.
Give them room to breathe. Bearded irises need good air circulation. Plant them a minimum of 16 to 18 inches apart (less space for dwarf irises and more for tall bearded iris varieties).
Do not mulch. Mulching helps the soil retain moisture, and too much moisture will cause the rhizomes to rot.
Remove seedpods that form after the blooms have faded. This prevents seedlings from choking the surrounding soil. Seed formation also saps energy needed by the rhizomes, roots, and leaves.
Prune back the foliage in the fall. This will reduce the chances of overwintering pests and diseases. Make dividing a habit. Divide clumps of bearded iris plants every three to four years in late summer.
