Caring for your Tall Bearded Iris 

On arrival

Unwrap the rhizome and plant as soon as it arrives. If unable to plant immediately, store in cool dry place.

Planting

Tall Bearded Irises enjoy a position that receives a few hours of sun each day.

When planting, spread the roots out (if the rhizome has any). These roots will die but they will help stabilise the rhizome while it develops new roots. The top of the rhizome should be flush with ground level so that it is exposed to the sun. (If planted too deep the rhizome will rot where the leaves join the rhizome.)

Water for a couple of weeks after planting.  Once new roots have formed the plant can withstand dry periods. 

Care

Fertilise with low nitrogen fertiliser in spring and autumn. They also appreciate some lime (or gypsum) once a year. Remove dead leaves and weeds.

They are prone to leaf spot which can be treated with a fungicide or general rose spray.

Divide clumps when they become crowded
