What needs to be done when transplanting a growing Iris plant so that it will live in the new hole?
The best time to transplant iris is late summer. Dig them up, cut off the tops leaving about 4 inches of leaf. Prepare the new site, make sure it has good drainage, is in a sunny location. Work compost into the soil so it has good soil to grow in. Then just barely bury the rhizone in the ground, so the top of the rhizone (root) is level with the ground surface or just below the surface. If you plant it to deep it will not bloom. I like to use all purpose Miracle Grow on my plants to help reduce transplant shock and to give them a boost. If you have round-oval spots on the leaves of your iris, you have a fungus on them and it will affect how they grow and survive. If you do, after you cut the leaves off, trim the roots off to about 5" in length, and soak the plants in bleach water, for about 10-15 min. ( 1/2 cup of bleach in 2 gallons of water). This will kill the fungus, so you don't transmit it to the new home. Also plant them in a new area, because the other area is contaminated. You can plant something else there, but not lilies, so the spot isn't empty. In the fall, I trim off the tops of my plants, and pick up all dead leaves, in case there is any disease on the plant, that helps reduce carrying it over into the next year. I "feed" my plants throughout the year to keep them healthy. Irises like to have sun on their rhizones, so don't mulch them very much. You need to transplant about every 4 years, otherwise they get too thick and will stop blooming when they are crowded. I just give the extras away, as long as they are not infected. Do not put infected plants in your compost pile, because you can just spread it that way. I throw mine in our woods, away from my gardens, so I don't ever put that soil back on my garden. Remember preparation is a very important step in growing anything. You can't expect to grow beautiful flowers in unfruitful soil.
Reply:Iris are grown from rhizomes that are divided and planted in late summer through early fall. Transplanting a grown plant is wish full thinking. Enjoy it where it is and move the tuber to it's desired location at summers end. You may be Lucky enough to double or even triple the amount of blooms in the spring.
Reply:first off water the ground and be careful not to hurt the root.try to dig it up in one big scoop and then just transplant to new spot without removing the dirt from the bottom.Do it AFTER the sun is down and you may want to keep it from full sun for a few days till it takes hold again.I've done this lots make sure you re-water after placing in new spot.
Reply:Bearded Iris needs to be divided every three years or so or it stops blooming.

It is easily transplanted, especially this time of year. Just divide up large clumps so that each piece has a piece of root. Cut off any rotten parts. The larger roots or rhizomes will still support blooms this year. Plant the roots a couple of inches deep, not too deep. Plant about 14 inches apart. Water well....
