Characteristics of the iris
Why are irises so popular among gardeners? Let’s look at some reasons.
Iris is a hardy perennial that grows well in a variety of climates. Some varieties grow well in cold climates, while others grow well in hot regions prone to drought. (Hello, Zone 8a, North Texas).
Once established, irises require little maintenance and are easy to care for. Regular watering (especially during dry periods) and balanced fertilizers are about all these plants need.
Irises grow well in a variety of soils, but do best in well-drained soil and in full sun to partial shade.
How to plant iris
The best time to plant irises is late summer to early fall, usually from July to September. This gives the plants time to establish roots before winter.
Choose a site with well-drained soil that receives at least 6 hours of direct sunlight per day. Iris does not like to sit in soggy soil.
Amend the soil If necessary, amend heavy clay soils with organic matter (compost or peat moss) to improve drainage. Aim for a neutral to slightly acidic pH (6.8-7.0). Adjust soil pH as needed.
Plant so that the top of the rhizome is just below the soil surface or slightly exposed. If you are planting in a warm climate, you can cover it lightly with soil. Space rhizomes 12 to 24 inches apart to allow for growth and air circulation.

Planting procedure
Dig a shallow hole: Dig a hole large enough to accommodate the rhizomes and roots. Usually about 4 inches deep. Make a mound: Make a small mound of soil in the center of the hole. Place the rhizome: Place the rhizome on top of the mound and spread the roots out to the sides. Cover with soil: Fill the hole and cover the roots depending on the climate, leaving the top of the rhizome exposed or lightly covered. Water lightly: Water newly planted rhizomes to settle the soil around the roots, but avoid overwatering.
iris care
Apply a thin layer of mulch to retain moisture and suppress weeds, but keep it away from rhizomes to prevent rot.
watering
Water thoroughly after planting, and then water regularly until the plant is established to keep the soil moist (but not soggy). Once established, irises are relatively drought tolerant. Water if the dry period continues for a long time.
8. Fertilization
Fertilize in early spring and after flowering. Use a balanced fertilizer (10-10-10 or 5-10-5) to promote healthy growth and flowering.
maintenance
Keep the area around your iris weed-free to reduce competition for nutrients and water. Divide the rhizomes every 3-4 years to prevent overcrowding and maintain vigor.
