BETTER THAN CLAY POTS 
Ferto-Pots are manufactured from a rich rotted cow 
manure mixture in automatic pot machines and then 
kiln dried. 
The pots soften up only in moist soil 
after planting out after seedlings are big enough. 
Start your seeds, seedling plants, cuttings, bulbs, etc., 
in Ferto-Pots and insure quicker, better results; no 
wilt, no setback in transplanting. Pot goes into the 
ground without disturbance or shock to the root 
system and continues to feed the growing plant.

How To Use this Catalog 
N THIS SHORT GUIDE it is taken for granted that most trees and shrubs require normal food, air 
and water. Thus a plant needing more air than usual at its roots is marked “loose soil” or “drain”. 
Plants very easy to grow are referred to as “tolerant,” or may have no notes whatsoever. 
CLIMATE MAP 
The numbers | to VII in the map refer to Zone numbers printed after 
each plant name throughout this Guide. It shows the northern limit 
beyond which any given plant cannot grow. This is not a perfect 
rule. Two modifications might be mentioned. East of Indianapolis, 
a damper climate makes all evergreens hardier. West of Indian- 
apolis hot western summers make deciduous trees hardier than rated 
in this Guide. 
Light—"sun,” “shade.” 
Light makes the chlorophyl factory turn its wheels. All 
plants need some. Those that get along best on little 
light are marked “shade” in this Guide. Those that 
need a great deal are marked “sun.’“—Normal plants 
are not marked. 
Air—“loose,” “heavy,” “drain.” 
Roots get oxygen from air that filters into the earth. 
Some plants need more than others; these must have 
loose soil and will suffocate in heavy damp clays. 
Such plants are marked “drain.” 
Water—“damp,” “dry.” 
Roots can only use chemicals that are dissolved in 
water. Also, water is the means of transportation up 
the stem. Some plants need more than others and die 
in severe droughts. 
In the descriptions such are 
marked “damp.” A loose soil quickly dries, a heavy 
soil keeps damp. Thus water and air for the roots are 
beth present in a mixed soil. 
Food—"humus,” ich,” “barren.” 
a. Potassium—most soils have plenty. 
b. Phosphorus—needs to be added in most soils with 
fertilizer. 
c. Nitrogen—Fertilizer supplies it, but water quickly 
leaches it out, so permanent plants depend on bac- 
teria in the soil. These bacteria depend on:— 
1. Acidity of soil (lime, etc.). 
2. Drainage of soil (air). 
3. Humus in the soil (food).
