Irises Garden Plants
Irises garden plants are easy-to-grow perennials, making them a favorite of home gardeners. Irises garden plants, growing in shades of purple, pink, blue, yellow and many colors in between, are six-petaled flowers. They may be bearded or beardless, with smooth, symmetrical falls. If you want to grow irises garden plants, then here are several ways for you. Choose a location in the full sun or partial shade. Most irises like full sun. Plant them in partial shade only in a warm climate. Prepare the soil. Irises require good drainage. Till down 12 to 18 inches and mix in compost, peat or sand to avoid root rot. In clay soils, consider raised beds. Divide the long rhizomes into sections, each with one or two leaves growing up and several roots growing down. Dig shallow holes about 18 inches apart, and mound soil in the center of each hole. Place each rhizome section on the mound and arrange the roots so they hang down. Fill the holes so the roots are fully covered and the rhizome rests no more than 2 inches below the surface of the soil. Firmly press down the soil.
Cut off old stalks at ground level after flowering. Leave the green foliage intact. Remove the dead leaves from the base of the plant. Divide your irises and replant every three years. This prevents overcrowding and root rot. The best time to dig and separate is usually in late summer after the irises garden plants has finished blooming. Dig up the rhizome and wash off the soil. Divide and discard the old or soft sections. Let dry for a day and replant. Amend the soil with compost before planting.
