Iris

I have read on the website that it is a good idea to mulch bearded iris with manure. Do I cover the tuber??

    No. Keep the tuber clear so that it can get maximum sun.  :)

    The RHS says they are not hungry plants but will appreciate some well-rotted garden compost around but not on their rhizomes.  I would have thought manure would be far too rich for them.
