Iris Total Recall

Iris Total Recall should be planted shallowly, leaving the rhizome exposed at ground level. Add sand when the soil is too heavy or too wet, and place the rhizomes on small mounds. Ensure good drainage so that the irises do not rot. During summer, this iris should be watered 1 to 2 times a month. After flowering, cut the flower stems to 10 cm (4in) above the ground. Damaged leaves should only be removed in autumn. It is not a good idea to apply too much nitrogen as it weakens the plant and increases the number of leaves at the expense of flowers. Taller flower stalks can become brittle. The iris can be susceptible to heterosporiosis, a disease identified by oval brown spots. To prevent it, treat the irises with Bordeaux mixture at the beginning of the growing season. Divide the clumps every 4 years in summer after flowering by digging up the entire clump. Take the most beautiful young plants from the rhizome, usually those on the outer edge, and transplant them to an area where there have been no irises for at least a year
