Growing Instructions
Plant in the spring after all danger of frost has passed. Dutch Iris performs well in full sun locations. The ideal soil is rich and porous and drains well, yet still holds enough water for the roots. If your soil is heavy clay and drains slowly, or very sandy and does not hold water, add organic soil amendments like peat moss or ground bark. Spread a 3-4 inch layer of soil amendment if needed and incorporate into the soil to a depth of 10 inches. Plant bulbs 2-3" deep and 12-18" apart. Cover with soil. When planting a large number of bulbs in one bed, excavate the entire area to the recommended depth, work fertilizer into the bottom of the trench, set out bulbs and then cover all at once. Water thoroughly at planting. While actively growing, water frequently and thoroughly so that water will reach roots. Mulch to keep the soil cool and to prevent the soil from drying out. Fertilize twice a year. Do not cut foliage back until the leaves have yellowed and died. Lift and store over winter if planted in colder climates. Mulch in milder climates to protect from frost.
Care Tip
Dutch iris bulbs can be planted in spring or fall. Select a planting site that has reasonably fertile soil and plenty of moisture that will not allow the bulbs to dry out in summer. Good drainage and a sheltered location will help them survive the winter to return for years to come. Best planted in large groups of 15 bulbs per square foot. It is recommended that gardeners in zone 5 should add a 2" layer of mulch in fall.
