40 HAND BOOK FOR THE GARDEN 

Care should be exercised so as not to reduce the temperature of 
the frame late in the afternoon as such treatment is likely to cause 
frost injury. Coldframes are especially valuable for protecting Let- 
tuce, Parsley, Cauliflower and some other vegetables from late fall 
frosts. They are also useful for wintering over some of the less hardy 
perennial flowering plants. 
Fertilizers 
Mixed Fertilizers are obtainable in many brands of varying grades 
and analyses. A careful study of soil, and crops to be grown on it, is 
essential to determine the proper kind for best results. It is suggested 
that these problems be presented to your local seed or fertilizer dealer. 
A suitable blend or mixture for most garden soils consists of 4% 
Nitrogen, 12% Phosphoric Acid and 4% Potash. 
SHEEP MANURE 
Analysis: Ammonia, 2 per cent; Phosphoric Acid, 1 per cent; 
Potash, 2 per cent. 
This is a splendid, complete fertilizer containing the necessary 
plant foods and is also rich in humus, or vegetable matter. It is ex- 
cellent for general use either alone or in combination with other 
special purpose fertilizers. Having been kiln dried, there is little 
danger from weed seeds. 
STEAMED BONE MEAL 
This is similar to the Raw Bone Meal in analysis and fertilizing 
value, but dissolves in the soil more quickly. It may be applied in the 
same way as the Raw Bone Meal and is often used in the fall at the 
rate of 300 to 500 pounds per acre. If used in the spring, apply with 
cattle manure or sheep manure to form a complete fertilizer. Bone 
Meal furnishes a high percentage of phosphoric acid at a reasonable 
price. 
Analysis: Ammonia 2 per cent; total Phosphoric Acid, 24 per cent. 
Use 8 to 5 pounds of Bone Meal for each tree and vine when setting 
it out, working it in well around the roots. 
NITRATE OF SODA (16 PER CENT NITROGEN) 
Now recognized as the most desirable and most quickly available 
source of Nitrogen. 
There is no crop grown which is not greatly improved and in- 
creased in yield by an application of Nitrate of Soda, and for success- 
ful and profitable growing of many crops it has become a necessity, 
especially for grass, grain, corn, and garden truck. 
Use as a top dressing at the rate of 100 pounds per acre on the 
following vegetables when plants are well established: Beets, cab- 
bage, cauliflower, cucumbers, celery, egg plants, lettuce, spinach 
and onions. 
For asparagus, use at the rate of 250 pounds per acre as a top 
dressing after the first shoots make their appearance. 
For strawberries, use 100 pounds per acre as a top dressing after 
the plants have blossomed.
