square feet of ground is about the limit for a single application. We would recommend 
half of it at a time and repeat the application after two months. 
Applied to Vigoro, this formula would mean 20 pounds of Vigoro to every 1000 
square feet of ground, because Vigoro has four pounds of Nitrogen to every 100 
pounds of material. Such fertilizers must not come in contact with the plants, be¬ 
cause they burn. In dry weather, watering after application of fertilizer is necessary 
to make the fertilizer available. 
On our plantings we like to use Nitrophoska, which is convenient to use as 
well as being very efficient. Its convenience of use is due to the fact that it is coarse 
and will not adhere to and burn the foliage. We can, therefore, stand at one place 
and broadcast the fertilizer over a large area. This is a highly concentrated fertilizer 
containing 15% Nitrogen, 30% Phosphoric Acid and 15% Potash. 
DISEASES 
Buy healthy bulbs and do not let them come in contact with diseased ones. 
Throw out badly diseased bulbs. The rest can be treated with Semesan or Calogreen. 
Instructions how to apply come with the material. 
THRIPS 
Thrips have become so widespread in private gardens, that treatment should 
be given to all bulbs. We recommend Bichloride of Mercury. One ounce to 8 gallons 
of water (1-1000). Use only wooden or earthenware containers when treating the 
bulbs due to the fact that Bichloride of Mercury damages metal containers and be¬ 
comes ineffective. If you have the time to tear open the husks of the bulbs, so much 
the better. Soak for eight (8) hours. 
GARDEN BOOK 
A small Garden Book telling you in short how to treat your various plants is 
essential to success. It is cheap enough so that you can order it with your other re¬ 
quirements. Here it is: Better Gardening by H. O’Brien. Only 25c per copy.
