VIRUS FREE 



REGISTERED 



Plants referred to as "virus free" in this catalog have been field grown by us 

 from virus free foundation stock furnished by the U. S. Department of Agriculture, 

 Bureau of Plant Industry, Soils and Agricultural Engineering, Beltsville, Maryland. 

 Our field-grown stock has been dusted with parathion to control aphids which 

 transmit the virus diseases. It has also been grown at considerable distances 

 from any other strawberry plants. Since viruses do not produce clear cut symp- 

 toms in most strawberry varieties but simply weaken and devitalize the plants, 

 no guarantee can be made that these plants are 100% free of viruses. Because 

 of the measures that we have used to protect these plants from virus infection, 

 we believe them to be substantially virus free. 



All plants from virus free sources which meet the rigid growing requirements 

 of our Inspection Service are entitled to be sold as "Registered." All our virus 

 free varieties have met these requirements and will carry a label showing that 

 they are "registered." We hope W. F. Allen Company will receive your plant 

 orders, but in any event you should get plants which meet the rigid requirements 

 which entitle them to be registered. 



TRUE TO NAME 



We take every precaution to have all plants true to name and we will refund 

 your money if any prove otherwise, but we will not be responsible for any sum 

 greater than the cost of the plants ordered. 



SAWDUST MULCH SPACED PLANT SYSTEM 

 A Good Way to Grow Everbearers 



Everbearing strawberry production in Ohio shows that largest yields and highest profits 

 with greatest ease and economy of operation are secured by following a four-row bed type 

 planting system. (See diagram and picture.) 



In this system the plants are set one foot apart. A two-foot alley or middle is left between 

 each 4-row bed. The 4-row system produces high yields in August which are maintained 

 during the remainder of the season. 



The plants should be set just as early in the spring as the land can be prepared — late 

 March or early April. The first crop of weeds will usually appear within two or three weeks 

 after planting. These should be controlled by hoeing. After this first hoeing the entire area 

 should be covered with a layer of sawdust one inch thick. This mulch is very important for 

 conserving soil moisture and suppressing weed growth. Later weeds, if any must be removed 

 by pulling because hoeing would mix the sawdust with the soil and eliminate its mulch effect. 



Sawdust mulch helps to conserve soil 

 moisture during late summer and appears 

 to give adequate protection over the winter 

 period. A thin renewal layer may be needed 

 in the fall if the spring application was too 

 light. It is best to maintain a full inch of 

 mulch. 



All blossoms which develop on the 

 newly set plants should be removed until 

 early June, or later if plant growth has not 

 been vigorous. After fruit production starts 

 berries may be harvested about twice each 

 week until frost stops growth. If dry weather 

 occurs the crop can be greatly increased 

 in size and quality by irrigation. All runners 

 should be removed from the plants as fast 

 as they develop to insure highest yields. 



The Ohio system and variations have 

 been used in many areas for best results 

 with ever-bearers. The cost comes high per 

 acre with more plants and much hand labor 

 required. All reports indicate a carefully 

 managed small or medium size patch will 

 give high profits.
