Iris Maui Moonlight - Bearded Iris

Iris Maui Moonlight should be planted shallowly, with the rhizome just above the surface of the soil. 

In the shade, irises grow but do not flower. They are hardy and do not need winter protection. Well-drained soil is perfect, even dry, chalky or rocky. Excessively wet soil promotes rhizome rot. Plant from July to September to give the rhizomes enough time to grow and develop new roots before winter. They should be planted as soon as they are purchased for the best results. Plan to divide the irises every 4 years or so to give them fresh soil. They have vigorous growth and require space to develop and flower well. Plant with spacing appropriate to the size and vigour of the variety: approximately 34-50 cm (13-20in) for tall irises. Always consider the direction of rhizome growth, arranging them in a star shape with buds and leaves facing outward, and spacing them well away from other varieties to allow them room to grow.

Planting

Dig a hole that is wide and deep enough. Make a conical mound of soil on which to place the rhizome and spread out its roots. Cover the roots. It is important for the rhizome to be at the surface of the soil. It should not be planted in a dip (risk of rot). Take into account that the soil will settle and the iris will sink. In clay or wet soil, the rhizome can even be raised on a slight mound. To make the soil cling to the roots, lightly firm and water thoroughly after planting. Water 2-3 times if necessary until the plant takes root.

Maintenance:

Keep the soil free of weeds by lightly hoeing, taking care not to damage the rhizomes or roots. Weeds shade the irises, retain moisture (causing rot), and attract slugs. Also, remove dry leaves. If they are diseased (reddish-brown spots from heterosporiosis), we recommend burning them. Remove faded flowers.
