take off by compass up the old rootstalk . Use a shovel , spade , or fork to grok beneath the earth and pull out the mass of rhizomes .
The melodic theme is to use the tool that make the neat cut off through the rhizome to pull them out of the ground with little to no damage .
Once you ’ve gotten beneath the mass , made your excision , and have heaved it up from the ground , you should be staring at a large clunk of rhizomes . If you ’ve made it this far , you ’re starting off on a positive substructure in this process .
2. Separate the Iris Plant Rhizomes
The next step in the division process is to separate the mass of rhizomes into single rootstalk . calculate upon how firmly clump they are , will determine how you go about separating the mass .
If the rhizomes are loosely cluster together , you should be able-bodied to utilise your hand to carefully pull them aside .
However , if the masses is woven tightly , you may necessitate to employ a sharp tongue to separate it . It ’s vital to sanitize your knife in a bleaching agent solution between cuts .
If you slice up into a rootstalk that is infected , and do n’t sanitize your knife between cuts , you could spread the disease to other rhizomes . The sanitizing solution should be one - part blanching agent to ten parts pee .
Once your rhizomes are separate , begin look at them to see which are hefty and which are not . A healthy rhizome will be more or less two inches in diam , have a strong radical organization , and two or more leaves on it .
If the rootstalk do n’t appear young and intelligent , get disembarrass of them because they most probably wo n’t form healthy plant .

Again , make certain it ’s one - part bleach to ten parts water . This can aid ward off any diseases that may judge to ravage your freshly transpose rhizomes .
After disinfect , check your rootstalk one more time . If any have a bad odor about them or feel squashy , they do n’t need to make the undercut for transplanting .
4. Trim the Foliage of the New Iris Plant Rhizomes
Your rhizome are clean-living , disinfected , and thoroughly inspected . What could peradventure be provide ? All they demand now is a trim .
This is n’t for aesthetics . Instead , by lop the foliage back to only three to six column inch in length , it permit the plant to put all its energy into establishing a upstanding ancestor system .
If you lead the foliage longer , the works will send nutrients to it because it thinks it ’s still trying to maintain tone wellness in this area .
By cutting the foliage back , it sends a message to the industrial plant to disport the energy to the roots because that ’s where it ’s really needed .

You might be capable to get aside with them being a little nigher if you choose a miniature variety of the iris plant .
However , for large varieties of iris plants , you ’ll want to go with a magnanimous distance than two feet . Once the jam are dug , place the rhizome into the space .
guarantee the rhizome is erect while the root are spread out . The rhizome should be sitting at territory level where you may see at least one to two inches of it .
This will ensure it welcome proper sunlight while also avoiding put too much pressure level on the roots . If the rhizome is n’t model high enough , the roots can become compressed in the outer space .
When all the rhizomes have been planted , water them well . iris diaphragm only postulate water during drouth and right after organ transplant . By water them during this time , you ’re doing your part to give these plants a right kickoff .
