When is the best time to plant irises???
Answers: Bearded irises can be divided any time after your ultimate frost date in the spring, but the optimal time to divide them is 6-8 weeks after bloom. Avoid transplanting irises contained by very hot weather (90+ F degrees), but do return with them transplanted back into the ground a couple months previously freezing weather to give them time to root within well up to that time winter. Irises moved before bloom will recurrently lose their bloom that season, which is why it's best to wait until after bloom to verbs and divide.
Japanese and Siberian beardless iris may be divided best in untimely spring before growth starts. Later divisions during the spring and rash summer can be made, but plants are more difficult to establish. Avoid planting back into one and the same soil if these are Japanese Iris, Iris ensata, as they are allelopathic to all of their own genus, Iris. Renew the soil consequently plant if you desire another iris in that location.
Fall, a moment ago before the frost, is the best time to cut the rhizomes, set them on spaded or broken soil and weakly cover them with compost and topsoil, so the crowns peek out.
