HOW TO DIVIDE AND PLANT AN IRIS 



From a single rhizome planted in 

 1942 this crowded chimp 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 the 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 Society. 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 promptly.

membership in which will bring you four meaty bulletins per year. This 

 is the best way to keep informed on Iris progress, the latest awards, what 

 the experts think. These bulletins are really books themselves, generally 

 containing 100 pages or over per copy. Dues 13.50 per year and well 

 worth it. Send your remittance to us, we will enter membership for you.

A FEW CULTURAL TIPS 



WhOe 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 heax^y, fairly well enriched soil — in other words, ordinary good 

 garden soil — is to be preferred. Go easy on fertilizers, especially animal 

 fertilizer; 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 appearance 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 wath copper or Bordeaux solution. For 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 will be sent without charge to anyone 

 requesting it. 



IRIS BORER 



A new product has come to the front in combating borer. So many 

 people have used it successfully that we are glad to recommend it to 

 our customers. Write to Gray Incorporated, 7217 Division St., River 

 Forest, Illinois, for Gray's Iris Borer Eradicator, $1j50 for a 16-oz. bottle. 



TIME OF SHIPMENT, WHEN TO PLANT, TERMS, ETC. 



WE GUARANTEE all plants to be true to name, top quality and size, 

 free from insect pests and disease, and to reach you in a live and healthy 

 condition. If for any reason you are not completely satisfied, please notify 

 us promptly. 



TO CUSTOMERS IN CANADA: We ship many orders to Canada 

 every year. There is a simple procedure which all Canadians must follow, 

 however, in order to import Iris or other plant material. Make out the 

 list of items wanted, state name and address of firm you are ordering from 

 and send it to the Plant Import Division of your Department of Agri- 

 culture at Ottawa. They in turn will send you a permit number and 

 labels. Then you send your order, including the permit label, to us in 

 the usual way. 



NO SHIPMENTS MADE DURING SPRING MONTHS 

 FALL SHIPPING SEASON CLOSES IN LATE OCTOBER 



This catalog is free to all customers of record over a 2-year period, otherwise 

 copies may be obtained for 25c and this amount deducted from first order.

IRIS will be shipped beginning July 1st and continue tlirough the 

 summer and early fall. Earliest shipments will go to those who simply 

 MUST have the plants early, but it is obviously impossible for us to 

 deliver thousands of orders at the outset. During July and August we 

 will ship constantly in the sequence as received. Your success is assured 

 if planted any time during this period, but early ordering is advisable 

 to avoid stock being sold short. 



TRANSPORTATION is by prepaid parcel post or express, whichever 

 we deem most expedient. Be sure to state your express office if different 

 from postal address. 



TERMS are cash with the order, either check, draft or money order. 

 We do not advise the enclosun^ of currency with your order. No C.O.D. 

 shipments— this adds to cost and involves red tape for you and for us.
