Gardeners’ Forum: “Reblooming irises not reblooming”
Back to Gardeners’ ForumReblooming irises not reblooming
Posted by Donna on Monday, August 11, 2008 9:45 PM ADTI have several varieties of reblooming irises. They bloom once but I cannot get them to rebloom. Do I have to cut off old stalks once the flowers have died? Use a specific type of fertilizer? The first blooms are spectacular, and even though I know the second blooms are supposed to be less so, I would still like to get them. Any comments would be appreciated. Thanks!

Fertilizer should be applied as a side dressing in early spring. Fertilizer can burn rhizomes, and should be applied around the plant, not on it. A 5-10-5/5-10-10 or similar formula is best. You can also work compost into the soil around your Iris.
