Suggestions. — Flax requires its food to be in easily available 

 forms and the soil must, therefore, be in good condition. Flax 

 should be grown on the same land only once in four or five years, 

 as the decay of the roots in the soil appears to form products in- 

 jurious to the flax crop following. Stable manure, when used, 

 should bo applied to the preceding crop. 



Flowers and Flowering House Plants. 



Per Pounds for Pounds of different materials for one 

 cent, one acre. acre. 



Nitrogem 5 20 to 40 50 to 100 pounds nitrate of soda ; 



25 to 50 pounds sulphate of am- 

 monia; 100 to 200 pounds cotton 

 seed meal. 



Available phosphoric acid.. 7 30 to 00 200 to 400 pounds dissolved rock. 



Potash 5 20 to 40 40 to 80 pounds muriate of potash. 



Suggestions. — This mixture may be used for all kinds of flower- 

 ing plants grown out of doors. Where flowering plants are grown 

 out of doors only on a small scale, the above mixture can be ap- 

 plied at the rate of one ounce for three or four square feet. It 

 would be well to apply one-third before planting or setting, work- 

 ing the fertilizer lightly into the surface soil; then another third 

 after the plants are well up, and then the rest three or four weeks 

 la/ter. For flowering plants grown in a green house, the same 

 mixture can be used; or, if desired, the phosphoric acid can be 

 furnished in part by bone-meal. Apply liberally in soil at the 

 start, and later, apply every week one-half ounce nitrate of soda to 

 every 10 square feet of soil surface and once in two weeks use for 

 the same area one ounce of dissolved rock and one ounce of sul- 

 phate of potash. 



For flowering plants grown in pots, as in the case of house 

 plants, the above mixture may be used at the rate of half a toa- 

 spoonful for a six-inch pot once in two to four weeks, working 

 slightly into the soil. For larger or smaller pots, use in propor- 

 tion. For potted house plants, the following mixture may be 

 used also, when it is desired to make up small quantities for use 

 on only a few plants: Four ounces each of nitrate of soda, sul- 

 phate of ammonia and sulphate of potash and one pound of bone- 

 meal. They should be purchased in powdered form and then 

 carefully mixed together. Apply as directed above.
