Irises are one of the most rewarding and easy-to-grow bulbs, performing best in full sun. Soil should be well drained. Plant bearded iris bulbs in the fall for spring blooms.
Blooms first appear in April and, depending on the varieties, irises continue to bloom into summer. Today there are many Bearded Irises that are rebloomers or remontant irises. These will blossom a second time.
As soon as the last flower has faded, remove the spike.
1. Mix Pike Planting Mix into the planting area.
2. Dig a hole large enough to accommodate the root system.
3. In the bottom of each hole, mix into soil a small handful of E.B. Stone Bulb Food.
4. Plant so the top of the rhizome is just under the surface of the soil. Plant three rhizomes (bulbs) of the same variety at a time. Place 12 inches apart, two with growing points heading away from each other and a third pointed to fill the gap between them.
5. Water thoroughly.
If using a water-soluble fertilizer, feed every two weeks with Grow More Super Bloomer. Granular or dry fertilizers such as E.B. Stone Bulb Food can be applied every 4 to 6 weeks during the growing season.
E.B. Stone Sul-Po-Mag applied during spring will also help promote lusher foliage and brighter flowers.
Once established, bearded iris are very tolerant to dry conditions, but regular watering to supplement the rain will provide better-quality blooms and more of them. Soil should be kept moist but not soggy. Good drainage is a must.
Irises require very little maintenance. Immediately after flowering, remove the spent flower spikes by cutting off at ground level. Don’t be afraid to cut the blooms and bring the flowers inside and use in a fresh-cut floral arrangement.
