| Water | 100,000 parts |
One application of this a week is enough for the slower growing plants, and 2 for the more rapid growing herbaceous ones.
| VII.— | Calcium phosphate | 4 ounces |
|---|---|---|
| Potassium nitrate | 1 ounce | |

VIII.—Pot plants, especially flowering plants kept around the house, should be treated to an occasional dose of the following:

| Potassium nitrate | 2 parts | |
| Calcium acid phosphate | 8 parts |
About a teaspoonful of either of these mixtures is added to a gallon of water, and the plants sprinkled with the liquid.
For hastening the growth of flowers, the following fertilizer is recommended: {338}
