Fall Roots Upon Arrival:
It is very important to plant these dormant perennials as soon as possible after you receive them. If it is absolutely necessary to store them for a short time before planting them, open the cartons and any plastic that is around the roots. If the roots appear dry, soak them for a few hours in warm water. Thereafter store in slightly moist peat moss in a cold, but not freezing location until you can plant. They can also be placed in pots of soil if planting will be delayed for more than 2 weeks. Use any packaged, peat-based potting soil and pots with drainage holes. Most Bulbs, Perennials and many other garden plants require 'well-drained' soil in order to thrive. Areas that often have 'sitting' water or constantly soggy soil can quickly cause roots to rot and deteriorate, especially over winter.
Planting Roots General Info:
It is a good idea to soak any bare-root perennials in water for a few hours, but not more then a day, before planting. Add organic matter to the area and provide good drainage unless the plant variety enjoys wet roots. Unless otherwise specified, bare-root perennials are usually planted with the crown (where the shoots meet the roots) an inch below the soil surface. Firm soil gently to eliminate air pockets and water in well. Mark the area clearly since it may be awhile before the plant shows itself. Pay particular attention to watering any new plants during the first season. Once established plants generally have some drought tolerance and will only need to be watered if the season is hot and dry.
Set the rhizome just below the surface of the ground so that the top is exposed and with the true roots spread out into the soil below. Water the new plants every second day for the first ten days then cut back to once a week. Note that this is for new plantings only. Established iris clumps do not require water other than what they receive from natural rainfall unless you are experiencing a long drought period. Three rhizomes may be planted together to obtain a good sized clump more quickly. The downside to this is that you must be prepared to divide the plant sooner. Spacing of plants varies with space available but usually individual rhizomes are planted 16-18 inches apart and clumps 24-30 inches apart. This allows good air circulation around the plants and proper sun exposure.
Iris clumps should be dug up, divided and replanted every 3-4 years, as when the clumps become large and overcrowded, flower production is greatly reduced. Use a garden fork and carefully dig the planting out of the ground. Next wash the remaining soil off and pull apart the root tangle. Then divide the rhizomes into single plants with a leaf fan on each, using a small sharp knife if required. Discard the old and any diseased rhizomes. The leaf fans should then be cut down to approximately 6 inches. The retained sections should be allowed to dry overnight to allow cuts to seal up before replanting. This will minimize chances of disease invading the rhizomes.
