SOCIETY OF AMERICAN FLORISTS. 



Convention City Notes. 



A meeting of the advisory board was 

 held, with all the members of the com- 

 mittee present. 0. E. Critchell, Cin- 

 cinnati, and John Vounjj, secretary of 

 the S. A. F., were also in attendance. 

 The general situation regarding the 

 trade exhibit was reviewed and plans 

 were laid out whereby the exhibitors in 

 the trade section would be given suffi- 

 cient space by widening the aisles more 

 than has been done in past exhibitions 

 of this kind. Both the Auditorium and 

 the Coliseum are magnificent, large, light 

 halls, and all the exhibition space will 

 be on the'groun<l floors. 



All materials for structural work will 

 be placed in the Coliseum. At no pre- 

 vious convention have there been such 

 favorable opportunities to make dis- 

 plays. The fact that the ' ' outing ' ' day 

 will be the fifth of the convention will 

 give the trade people another day for 

 business without having any event to 

 distract the attention. 



But the most impressive thing was 

 the wonderful work that had been 

 accomplished by Theoilore Wirth and 

 others in Minnea|)olis, in conjunction 

 with the outdoor plant exhibition. Ad- 

 jacent to the Armory, where the con- 

 vention will he held, the surroundings 

 of the outdoor exhibit are naturally 

 beautiful and it behooves the growing 

 interests to give every support to this 

 laudable undertaking, this being the 

 first time when, by arrangement, the 

 society is in a position to guarantee the 

 plantsmen that their exhibits will be 

 cared for and grown on under every 

 favorable condition, having the con- 

 stant attention of competent help who 

 will be under the supervision of Mr. 

 Wirth. 



Everything is ready for immediate 

 planting, but, as the space is limited, 

 application for it should be made at 

 once to Secretary John Young, who is 

 superintendent of the trade exhibition. 

 He will forward applications immedi- 

 ately to Mr. Wirth. 



This outdoor plant exhibit will be a 

 success and will be one of the features 

 of future conventions. The price of 

 space is nominal — only sufficient to 

 cover the expense of planting and main- 

 tenance of the plants during the season. 



Outdoor plant exhibits must be 

 shipped, charges prepaid, to Theodore 

 Wirth, superintendent of ])arks, Minne- 

 apolis, Minn. John Young, Sec'y. 



Traer, la. — (,'urtis Thomas has pur- 

 chased materials for a new greenhouse, 

 to take the place of the house that 

 was recently damaged by a storm. He 

 will also use part of the framework 

 of the wrecked structure in the erec- 

 tion of two smaller houses. 



NEMATODES IN SOIL. 



I received your letter saying you 

 could not find any insect life in the 

 soil I sent you. The insects were in 

 the soil before I put it in the box; 

 what became of them I do not know. I 

 am sending you another sample and I 

 know positively that there are insects 

 in the box now; whether they will get 

 out of the package before it reaches 

 vou is another matter. C. P. 



The only insect life found in the soil 

 was a considerable number of nema- 

 todes. The well known disease, root- 

 knot, is cause<l by these nematodes. 

 Most of the ornamental and greenhouse 

 ])lants are more or less subject to root- 

 knot. The rapid multiplication of nem- 

 atodes is favored by a certain degree 

 of warmth, loose-textured soil, moisture 

 and food supply. 



The most efficient method for the 

 control of nemato<les itx greenhouses 

 and seed be<ls is the use of live steam. 

 However, if the use of steam is im- 

 l^racticable, the old, infested soil may 

 be entirely removed and the benches 

 thoroughly cleaned out. Then soil which 

 has been allowed to lie through the 

 winter in a place where it has been 

 exposed to freezing and thawing or dry- 

 ing, may be put in its place. Nematodes 

 will not resist alternate freezing and 

 thawing, so that the new soil put in the 

 benches will be free from nematodes. 



Old, infested soil may be treated with 

 a solution of formaldehyde, in the jno- 

 portions of one part commercial fot- 

 maldehyde to 100 parts of water, aiiit 

 the soil allowed to dry out for one to' 

 two weeks before using again.

WHITE FLY ON FUCHSIAS. 



Kndosed you will find some leaves 



of my fuchsias, with some insects on 



them. Please give me the formula for 



an insecticide that will destroy them. 



T. F. 



The fuchsia foliage is smothered with 

 white fly. To get absolute control of 

 this is difficult, outside of the use of 

 hydrocyanic acid gas. Spraying with 

 soap and water is a partial remedy and 

 is favored by those who are afraid to 

 use the gas. If you have a mixed as- 

 sortment of plants there will, of course, 

 be <langer of some being injured by the 

 gas, but a light dose, properly applied, 

 will do a minimum of harm provided the 

 nights selected for fumigation are cool. 



If you want to use the gas, secure 

 some cyanide of potassium, ninety-eight 

 per cent pure; also some sulphuric acid. 

 You will also need some stone jars, as 

 the acid would eat away any metal 

 ones. The length of your house, mul- 

 tiplied by the breadth and this again 

 multiplied by the average height, will 

 give the space in cubic feet. Select 

 a cool evening for fumigating. Be sure 

 all ventilators are tight. Stand the 

 jars twenty-five or thirty feet apart, or 

 farther apart than this if the house is 

 narrow. Divide the materials into por- 

 tions for the jars, according to the 

 area and the number of jars to be used. 

 For each .S,000 cubic feet use one and 

 one-fourth ounces of cyanide, two and 

 one-fourth ounces sulphuric acid and 

 three and one-half ounces water. Place 

 the water first in the jars; then add 

 the sulphuric acid; then start at one 

 end of the house and drop in the cyan- 

 ide, wrapped in oil paper. Walk toward 

 the exit, drooping in the cyanide as 

 vou "o. Lock the door securely and 

 allow no one to enter until morning.
