HOW TO DIVIDI 



From a single rhizome planted in 

 1942 this crowded clump was overdue 

 for dividing in 1947. Note rhizomes 

 growing over one another in center of 

 clump. 



After being dug, clump was cleaned 

 with stream from hose. Note that healthy, 

 growing rhizomes circle the clump, 

 while those in center have very few 

 white feeding roots. 



Healthy, growing rhizomes are separ- 

 ated from old bloomstalks. Some prefer 

 "doubles" as in foreground for replant- 

 ing. Wash rhizomes thoroughly before 

 replanting. 



THE ABOVE SERIES OF PICTURES 



is taken from the new book "THE IRIS, AN IDEAL HARDY 

 PERENNIAL," recently published by the American Iris Soci- 

 ety. This is as nearly complete as the experts have been able to 

 make it — chapters on the various groups, types and species, 

 every phase of culture, the fine points of Iris breeding, diseases 

 and pests, all about the American Iris Society, Iris judging, 

 photography, uses of Irises in the garden, and so on. 226 pages, 

 well illustrated. Heavy paper binding, ^1.50; permanent cloth 

 binding, ^2.50. Send your order to us and we will ship prompt-

IRIS FOR EVERY GARDEN 

 By Sidney B. Mitchell 



The most up-to-date and complete book on Iris 

 ever written with all basic information for ama- 

 teurs and for specialists, an authentic discussion 

 of species and varieties all over the world. 

 With this book as a guide you can select Irises to 

 bloom from 3 to 12 months a year, depending 

 on where you live and what you plant — the fa- 

 miliar bearded, the Japanese, Siberian, Louisiana 

 types, or certain rare and fascinating species. Dr. 

 Mitchell has grown Iris for 50 years, has himself developed 

 new varieties, and shows you the way to special satisfaction 

 with this "finest hardy perennial." 224 pages of text, plus 12 

 pages of how-to drawings and plans. 25 species and varieties 

 illustrated in full color. $3.00 per copy. Send orders directly 

 to us. 



A FEW CULTURAL TIPS 



While it is true that Irises are among the easiest of all plants 

 to grow, anyone who plans to grow even a few Irises should 

 not be content to achieve merely indifferent results. Most Irises 

 will succeed well in any type of soil from almost pure sand to 

 stiff clay. Where one may choose, a medium heavy, fairly well 

 enriched soil — in other words, ordinary good garden soil — is 

 to be preferred. Go easy on fertilizers, especially animal fertil- 

 izer; this sometimes promotes lush growth and eventual rot! 

 Bone meal, well worked in, is safe, and good. 



Don't plant in deeply shaded situation, and avoid places 

 where roots of large trees or big shrubs rob the soil of plant 

 food and moisture. Be sure drainage is good. 



Plant at least two feet apart; after first year, sparse appear- 

 ance will have vanished. If immediate effect is desired, plant in 

 groups of three of a kind, about a foot apart, the groups at 3- 

 foot intervals. 



DISEASES AND PESTS 



Although comparatively free from garden enemies, soft rot 

 of the rhizomes or spotting of the foliage sometimes manifests 

 itself. The former, usually the result of poor drainage or an 

 over-wet season, can be controlled by cutting back to sound 

 tissue or replanting. Leaf spot, like the measles, is not fatal. 

 Cut away and burn infected foliage and dust with copper or 

 Bordeaux solution. For Iris borer, or more detailed information 

 on any of these subjects, drop a post card and ask for our 3- 

 page leaflet on "Culture of Bearded Iris." It was included as an 

 insert in last year's catalog, but it will be sent without charge 

 to anyone requesting it.
