fection, and White Enchantress and 

 White Perfection last year lead to the 

 belief that its solubility in water is 

 not sufficient to cause injury to the 

 plants. 



Physical conditions of the soil may 

 be a factor in the injury. Acid phos- 

 phate and sodium phosphate in large 

 quantities give a pulverulent, quickly 

 drying soil of excellent texture, 

 Tvhile dried blood in large amounts 

 causes the soil to retain large 

 quantities of water. It does not dry 

 readily and so is not watered so often, 

 and yet the tenacity with which the 

 organic matter in the dried blood re- 

 tains the water prevents as large a 

 proportion of it being used by the 

 plant. This in turn prevents the 

 proper aeration of the roots that is an 

 essential benefit derived from the al- 

 .ternate wetting and drying of the soil. 

 The effects of overfeeding are not so 

 apparent with carnations as with 

 roses. In addition to the need for ap- 

 plying quantities of fertilizer not in 

 excess of that needed to the rose, it is 

 necessary to take into consideration 

 also the period of growth of the plant 

 when making application of fertilizer 

 to roses, a precaution that so far has 

 not been found necessary with carna- 

 tions. The necessity of observing this 

 ■precaution is well illustrated by the 

 experience gained with application of 

 fertilizer to roses during the present 

 season, an experience that came near 

 resulting in a complete loss of the 

 plants. 



The roses (young stock) were set in 

 the benches on August 4, at which 

 time five pounds of sulphate of am- 

 monia per 100 square feet and vary- 

 ing quantities of acid phosphate with 

 a little potassium sulphate were added 

 to the soil, together with a small 

 •amount of well rotted manure. A good 

 •crop of flowers was obtained on No- 

 vember 30, a like application of sul- 

 phate of ammonia and acid phosphate 

 was made to the sections. The roses 

 were off crop at this time. A good 

 many older leaves were dropped be- 

 cause the fertilizer was cultivated in 

 too deep, and the root system dis- 

 turbed. However, the flowers pro- 

 duced until the first of the year were 

 good. At this time, the new foliage 

 -which appeared to replace the flowers 

 removed showed marked signs of in- 

 jury from overfeeding, the symptoms 

 being weak growth and lack of chloro- 

 phyll in the leaves. The injury was 

 worse on the own root plants than the 

 grafted, and more marked on the side 

 of the bench from which water was 

 applied. It is clear that the condition 

 of the plant is a factor to be reckoned 

 with most carefully in the application 

 of fertilizer. The excellent condition 

 ■of those plants which have received no 

 fertilizer would indicate, indeed, that 

 no or little fertilizer is needed in the

earlier part of the season, although 

 past experiments have shown that the 

 soil used at the Experiment Station, 

 although rich, will not suffice to keep 

 a rose in best condition throughout 

 the season. The whole question of the 

 time of (ippUcation of fertilizers from 

 these two standpoints is one requiring 

 further study before definite conclu- 

 sions may be drawn. 



In an article appearing in the Amer- 

 ican Florist of July 19, 1913, calcula- 

 tions were given from the results of 

 analyses of liquid manure, showing its 

 strength to be equivalent to about 6 

 oz. of ammonium sulphate per 50 gals, 

 of water, and mention made that a 

 strength of 1 lb. per 50 gals, was often 

 recommended. Thirty - two grafted 

 plants each of Killarney and Rich- 

 mond roses have been so fertilized 

 during the winter. One-half of them 

 received weekly a solution of the 

 strength of 4 lbs. per 50 gals, of water, 

 while to the others a solution one- 

 fourth as concentrated was applied. 

 The soil was not drenched, but well 

 covered with the liquid. No injury 

 has been noted to these plants, al- 

 though during the protracted cloudy 

 weather of November and December 

 last, the foliage lost some color, as 

 was the case with all the roses regard- 

 less of the treatment.

St. Paul, Minn. — Plans for the serv- 

 ice building and greenhouse being 

 erected in Como Park, have been 

 found defective by C. A. Hausler, city 

 architect. Mr. Hausler says the plans 

 are incomplete and slovenly. The Toltz 

 Engineering Company is superintend- 

 ing the construction. Mr. Hausler says. 

 Th's company gets 3 per cent on about 

 $59,000 for checking up the steel in 

 the greenhouse construction. It gets 

 5 per cent on a stack and 5 per cent on 

 the service building. A written report 

 upon conditions will be filed by Mr. 

 Hausler with the commissioner of 

 parks, playgrounds and public build- 

 ings today. The city architect will 

 take over supervision of the work, un- 

 less the city has been bound by con- 

 tract to have the private company fin- 

 ish this job.
