THE VERY NEWEST AND QUICKEST METHOD OF DESTROYING WEEDS, 



GRASS AND OTHER GROWTH IN GARDEN WALKS, GUTTERS, 



TENNIS COURTS, DRIVEWAYS, ETC. 



This fluid absolutely destroys all weeds and otber growth wherever appUed, 

 and Its e£fect on the ground prevents the growth of fresh ones for a year and 

 thus saves a great deal of time and labor, aa no cutting, hoeing or hauling away 

 of the weeds is required. 

 We manufacture the strongest line of DISINFECTANTS on the market.

in the increased number of exhibitors 

 and visitors during the entire sliow, 

 and the interest shown by the various 

 garden clubs, some of whicli are now 

 affiliated with our Society. A large 

 number of the retail florists put up 

 splendid displays. 



We expect to give an exhibition this 

 year in New York combined with the 

 Institute management and should a 

 kind providence smile upon us and 

 our fields and gardens yield an abund- 

 ant harvest of flowers, we hope to show 

 the world one of the finest and best 

 dahlia shows ever staged. We are also 

 under promise to help and assist other 

 dahlia shows whenever and wherever 

 possible, and with our various trial 

 grounds we hope to be able to test oat 

 all varieties in commerce and advise 

 growers both large and small as to the 

 best varieties to plant, both for com- 

 mercial and private purposes.

INSECTICIDES; OLD CYCLAMENS. 



Mr. Editor : 



Dear Sir — Will you please tell me through 

 Horticulture the best insecticide to use for 

 spra.vinf,' roses out of doors, mostly Kani- 

 blers and a few other kinds. Also what is 

 the right treatment for some large old 

 eyolauieu roots through the summer time. 

 By doing so you will greatly oblige 



C. N. 



There are so many insecticides on 

 the market now, each one having its 

 advocates, that we would not feel 

 justified in recommending any par- 

 ticular one as "best." For aphides 

 we know of nothing better than 

 Aphine; for the rose slug. Lemon Oil 

 is well recommended; for the leaf 

 roller, powdered hellebore applied 

 early is a standard; for black spot, a 

 mixture of 5 oz. carbonate of copper 

 compound to 3 quarts of ammonia and 

 60 gals, of water is prescribed in the 

 Garden Library book on Roses. 

 Pungine and Vermine both have 

 proven valuable. Full directions tor 

 use are given with each package of 

 these standard mixtures. Buy them 

 from advertisers in Hortkui.tike. 



The best treatment for old cycla- 

 men plants, from the commercial 

 plantsman's view is to consign them 

 to the rubbish dump. But if one 

 wishes to carry them over, the best 

 plan is, after they have finished flow- 

 ering, to give them a short rest, say 

 a few weeks, and then repot them, 

 first into smaller pots. They should 

 not be "dried off" completely nor any- 

 thing done to injure the roots. In re- 

 potting, the old soil must be removed 

 with great care so that the roots may 

 not suffer the slightest damage. 



THE OUTLOOK FOR DUTCH AND 

 DANISH SUPPLIES. 



August Rolker & Sons have just re- 

 ceived the following letter from the 

 office of the Secretary of State at 

 Washington. It may be of interest to 

 importing firms: 



"The Department has received your 

 letter of May 24, 1917. with reference 

 to possible difficulties in regard to ob- 

 taining horticultural supplies from 

 Holland and Denmark. 



"No regulations have been made by 

 the Government of the United States 

 with reference to the importation of 

 goods of Dutch or Danish origin from 

 those countries, and should any action 

 be taken due publicity will be given 

 thereto. It is not. however, antici- 

 pated that any regulations of this Gov- 

 ernment will be directed toward a 

 limitation or regulation of the impor- 

 tation into the XTnited States of goods 

 of Danish or Dutch origin."
