WILD ROSE IRIS GARDEN 
The two main pests of German Iris are borer and rot, the rot usually 
getting in after borers have injured the roots. Borers hatch from 
eggs laid by a little moth on the leaves. The tiny borer bores into 
the leaf near the top and eats its way leisurely downward until it 
is fully grown by the time it reaches the rhizome. If you watch 
for it, you can head it off by squeezing or cutting off and destroying 
the leaf. 
The Ranedy 
Make raised beds or ridges, so water cannot stand around the plants, 
plant very shallow—the top of the rhizome should be at the surface 
of the ground. Next, if rot should develop, scrape the soil from 
around the rhizome, clean out the rotted parts, sprinkle with pow¬ 
dered sulphur, let the sun shine on the rhizome and you will soon 
be rid of rot. 
A light covering of straw or coarse hay put on after the ground 
freezes will help to carry your plants,safely through the winter.
