When writing our Free Service Department for information, please enclose postage for reply. 
To assist you in making out your order for Kellogg Pedigree Plants, we offer the fol- 
lowing suggestions: 
It is not necessary for you to send us sample of your soil, as any soil which will produce 
common farm crops or garden vegetables will grow Kellogg strawberries successfully. 
The number of plants required depends upon the system you wish to follow. We recom- 
mend either the hill or single hedge row systems. For the hill system, rows are made 30 in- 
ches apart and plants set 15 inches apart in the row, requiring 14,000 plants per acre or 
approximately 100 per square rod. For the hedge row system, rows are made 3 feet apart 
and plants set 2 feet apart in the row, requiring 7,000 plants per acre or 50 per square rod. 
All varieties indicated thus (P) are female or pistillate and require mating which means 
that bisexuals (of the same season) indicated (B) must be set with them. It is unnecessary 
however, to mate bisexual varieties, as bisexuals fruit independently. Female or pistillate 
varieties may be mated by setting alternate rows of bisexual and pistillate, or by following 
each row of bisexual with three rows of pistillate. The first method requires an equal num- 
ber of bisexual and pistillate, and the latter only one-third as many bisexual as pistillate. 
Strawberry plants should be set in the spring only — during April or May, at your regular 
garden making time. We begin shipping as soon as weather conditions permit, usually 
about April first, and do not make any shipments after May 25. Please do not ask us to 
ship plants at any other time, as we absolutely must refuse. 
Your order should besentto us as early as possible to be sure of getting the varieties you 
desire. Every year we are compelled to disappoint thousands whose orders are received 
late in the season. In 1919, we were obliged to disappoint more than 4,000 customers by re- 
turning their money because their orders reached us after our plants were all sold. PREVENT 
THIS DISAPPOINTIMENT BY SENDING US YOUR ORDER TODAY, SO THAT WE MAY 
RESERVE YOUR PLANTS AND SHIP THEM AT THE PROPER PLANTING TIME. 
If you are not familiar with varieties, tell us the number of plants you wish to set, the 
dimensions of the ground you intend to set to strawberries, or send us the amount you wish 
to invest in plants, and our Free Service Department will submit for your approval a list 
showing number of plants and varieties best adapted to your particular conditions. 
The Difference Between Standard and Everbearing Varieties 
Peerless, Progressive, Superb and Perfection are the only everbearing varieties we are grow- 
ing this year. All other varieties listed in this book are standard varieties. 
The everbearers produce a late summer and fall crop the same season the plants are set 
and the second year, fruit almost continuously from June to November, with the excep- 
tion of a short rest period during July. 
Standard varieties fruit only in the spring and early summer and should never be al- 
lowed to fruit the same season they are set. 
We offer this explanation so that you will not confuse the standard and everbearing 
varieties in making out your order. 
Kellogg Pedigree Plants, grown the Kellogg Way and backed 
by Kellogg's Free Service, insure your complete success.
