Part 215

V.—Sodium phosphate 4 ounces Sodium nitrate 4 ounces Ammonium sulphate 2 ounces Sugar 1 ounce

Use 2 teaspoonfuls to a gallon of water.

VI.—Ammonium phosphate 30 parts Sodium nitrate 25 parts Potassium nitrate 25 parts Ammonium sulphate 20 parts 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 Potassium phosphate 1 ounce Magnesium sulphate 1 ounce Iron (ferric) phosphate 100 grains

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

Ammonium chloride 2 parts Sodium phosphate 4 parts Sodium nitrate 3 parts Water 80 parts

Mix and dissolve. To use, add 25 drops to the quart of water, and use as in ordinary watering.

IX.—Sugar 1 part Potassium nitrate 2 parts Ammonium sulphate 4 parts

X.—Ferric phosphate 1 part Magnesium sulphate 2 parts Potassium phosphate 2 parts 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}

XI.—Potassium nitrate 30 parts Potassium phosphate 25 parts Ammonium sulphate 10 parts Ammonium nitrate 35 parts

The following five are especially recommended for indoor use:

XII.—Sodium chloride 10 parts Potassium nitrate 5 parts Magnesium sulphate 5 parts Magnesia 1 part Sodium phosphate 2 parts

Mixed and bottled. Dissolve a teaspoonful daily in a quart of water and water the plants with the solution.

XIII.—Ammonium nitrate 40 parts Potassium nitrate 90 parts Ammonium phosphate 50 parts

Two grams is sufficient for a medium-sized flower pot.

XIV.—Ammonium sulphate 10 parts Sodium chloride 10 parts Potassium nitrate 5 parts Magnesium sulphate 5 parts Magnesium carbonate 1 part Sodium phosphate 20 parts

One teaspoonful to 1 quart of water.

XV.—Ammonium nitrate 40 parts Ammonium phosphate 20 parts Potassium nitrate 0.25 parts Ammonium chloride 5 parts Calcium sulphate 6 parts Ferrous sulphate 4 parts

Dissolve 2 parts in 1,000 of water, and water the plants with the solution.

XVI.—Potassium nitrate 20 parts Potassium phosphate 25 parts Ammonium sulphate 10 parts Ammonium nitrate 35 parts

This mixture produces a luxuriant foliage. If blooms are desired, dispense with the ammonium nitrate.

XVII.—Saltpeter, 5 parts; cooking salt, 10 parts; bitter salt, 5 parts; magnesia, 1 part; sodium phosphate, 2 parts. Mix and fill in bottles. Dissolve a teaspoonful in 1 3⁠/⁠4 pints of hot water, and water the flower pots with it each day.

XVIII.—Ammonium sulphate, 30 parts; sodium chloride, 30 parts; potash niter, 15 parts; magnesium sulphate, 15 parts; magnesium phosphate, 4 parts; sodium phosphate, 6 parts. Dissolve 1 part in 1,000 parts water, and apply 3 times per day.

XIX.—Calcium nitrate, 71 parts; potassium chlorate, 15 parts; magnesium sulphate, 12.5 parts; potassium phosphate, 13.3 parts; freshly precipitated ferric phosphate, 3.2 parts. A solution of 1 in 1,000 of this mixture is applied, alternating with water, to the plants. After using a certain quantity, pour on only water.

XX.—Ammonium phosphate, 300 parts; sodium nitrate, 250 parts; potassium nitrate, 250 parts; and ammonium sulphate, 200 parts, are mixed together. To every 1,000 parts of water dissolve 2 parts of the mixture, and water the potted plants once a week with this solution.
