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.
