Tall Bearded Iris

Tall Bearded Iris can be challenging to grow in Houston’s hot, humid climate. These iris need friable, slightly alkaline soil, careful watering, and sun. Light is very important. A raised bed or container is necessary. Plant rhizomes 18”-24” apart, just below the surface of the soil, 1/4” of soil on top. Keep watered, but not wet, until new growth appears. Fertilize in small amounts 6-8 weeks before bloom is expected in late March and early April. While blooming, keep the beds damp but not wet to promote blossoms. After flowering, water less often/lightly over the summer. Full sun.
