Gardens Lifting water irises
HAVE lovely water irises in my pond. Should I lift them for the
they are Japanese irises, then yes. However, if they are other types,
such as Siberian irises or Louisiana irises, then no.
In either case, you should
wait until the green foliage has died down and gone brown. This
allows nutrients to build up in the rhizome and ensures a strong
plant for the following season.
