HUMUS:—in some torm, is useful to all plants. 
1. Lightens heavy soil. 
2. Adds water storage to light soils. 
3. Is nature’s own food. 
Warning:—Renew every. two years. 
Peat Moss:—The best all around humus. Safe 
and clean. 
Leafmold, woods clearings, dead leaves, etc. 
Also gcod, though apt to be unsightly, un- 
less finely shredded. 
2  Mulchnur:—See below. 
1 LIME:— 
n 1. “Sweetens” the soil — that is, 
0 acidity. (For Lilacs, etc.). 
2. Promotes decay, so provides quick food 
from humus in soil. 
Flocculates clay soils:—Thus making clay 
into loam.

Ways to Improve Your Soil 
ACID:—To acidify soils the safest thing is Alumi- 
num Sulphate. Spread 2 cup on | sq. yd. 
This over 2 months slowly dissolves in water. 
§ H:SO, (sulphuric acid) 
1 AlO—(sand-like, inert) 
FERTILIZER:—All plants in gardens benefit by 
having plenty of food. 
AlsSO, 12 H,O = 
1. Strong growth—hence increased hardiness. 
2. More flowers. Better color. 
3. Healthy plants—hence freer of disease and 
and insect troubles. There are 3 main foods 
needed:—Notrogen, Phosphorus, Potassium. 
These in various proportions are provided 
in Fertilizers. See Mulchnur below. 
USE NATURAL FERTILIZERS for PERMANENT RESULTS

‘ 1. High natural fertilizing value; feeds soil. 
2. Increases moisture-absorption; holds water 
‘4 through drought; conditions soil.

post is ready to be used like manure. One

CLIMATE MAP 
The numbers I to VII in the 
map refer to Zone numb 
printed after each plant name 
throughout this Guide. It 
shows the northern limit be- 
yond which any given plant 
cannot grow. This is not a 
perfect rule. Two modifica- 
tions might be mentioned. East 
of Indianapolis, a damper cli- 
mate makes all 
evergreens 
hardier. West of Indianapolis 
hot western summers make 
deciduous tress hardier than 
rated in this Guide.
