Discover the number one reason why bearded irises fail to bloom, and learn how to prevent it. This simple planting tip will ensure your irises thrive and produce beautiful flowers year after year.
Keep in mind that when irises are planted too deeply or in a location that lacks enough sunlight, they'll put out foliage but may not bloom.
Here's what you need to know to plant them right and get the most blooms.
Bearded irises grow from underground stems called rhizomes, which produce new leaves and flowers each year.
For best results, plant them in late summer or early fall so they establish themselves before cold winter temperatures arrive.
Dig a shallow hole in full sun and well draining soil, around 4 inches deep. Create a small mound of soil in the center of the hole.
Place the rhizome on top of the mound, with the roots spread downwards and the fan of leaves facing outwards. The top part of the rhizome (where the leaves emerge) should be slightly exposed, not buried deeply.
When mulching the garden, make sure the rhizomes are not covered by the mulch. If they are, they may not bloom.
