Digging up and Re-Planting Iris Plants

Hello all

I Hope you are Well.

When I had the Patio, Paving and Setts re-laid, due to Poor Work by the previous Landscapers, the Levels were adjusted.

Due to this the Borders in the Lower part of the Garden were lower than previously.

This has meant that the Soil Levels in some Borders were Higher than the Paving.

Last Year, I dug up some Plants, adjusted the Soil Level and then Re-Planted them.

However, I have Two Clumps of, I believe, Iris Ensata although they could be Sibirica, which are still Higher than the Paving since I did not know how to proceed with them.



Then, things went off a Cliff and I never got round to sorting them.

With these Iris Plants, how should I proceed to Dig them up, is there anything I need to be aware of, and how Deep should they be Planted?

I am looking forward to March so I can finally get back out in the Garden.

Thanks for any advice, it is appreciated.

Kevin
