THE VALUE OF SPRAYING. 



137 



A Profitable Investment 



iT would be difficult to find a fruit grower 

 who is more firmly convinced of the 

 value of spraying than is Mr. Joseph Twed- 

 dle, of Fruitland, Ont., whose place was vis- 

 ited recently by a representative of The 

 Horticulturist. " I have been using a 

 power sprayer for two years," said Mr. 

 Tweddle, " with w'hich I spray 100 acres of 

 fruit, and my sprayer, although an expen- 

 sive one, paid for itself, several times over, 

 the first year. I spray two to four times, 

 depending on the season, and aim to secure 



Spraying in Mr. Tweddle's Orchard 



75 to 90 per cent, of clean apples. My peach 

 trees are only sprayed once. 



" For killing insects, such as the curculio, 

 my belief is that the old formula of four 

 ounces of paris green to 40 gallons of Bor- 

 deaux is not strong enough to do quick 

 work, as the insects are able to do consider- 

 able damage before that soilution, which 

 works slowly, destroys them. I use half a 

 pound of white arsenic of lead, costing five 

 cents, which is boiled for three-quarters of 



an hour in one pound of fresh Hme, or boiled 

 with two pounds of sal soda. This mix- 

 ture has proved very efifective. If applied 

 too coarsely it may burn the trees, but if the 

 spray is fine no damage should occur." 



Trimming Trees 



PROF. H. L. HUTT, O. A. C, GUELPH, ONT. 



What season or month is the best for trim- 

 ming trees ? Should all fruit trees be pruned 

 at the same time ? When should shade trees 

 be attended to ? — (Amos Briuge, Brantford, 

 Ont. 



The safest time to prune or trim trees of 

 all kinds is early in the spring after severe 

 frosts are over and before growth starts. 

 There is then little danger of the trees be- 

 ing injured by frost and severe winter 

 weather, and wounds made at that time heal 

 readily. 



With maples and other trees, which 

 naturally bleed freely when pruned, it is 

 just as well to leave the trimming till late 

 in the spring when they will not bleed so 

 much. Bleeding is not so serious an in- 

 jury as is usually supposed, but often forms 

 a lodgment for spores of fungous diseases, 

 which are the cause of rot. 



Arrested Growth of Trees 



\V. T. MACOUN, C. E. F., OTTAWA. 



I have some apple trees planted last spring 

 that have not shown any sign of growth; also 

 an Austrian pine. The apple trees are green 

 and the pine holds its leaves. Will they grow 

 this spring, or would you advise planting other 

 trees in their places ? — (Chas. Derdaele, Wal- 

 kerton, Ont. 



If the apple trees and the pine tree were 

 alive in the autumn of 1904 it is quite likely 

 they will live. It frequently happens when 

 trees are received in poor condition, or if 

 the soil is not properly prepared, or the 

 trees not planted carefully, they will make- 

 little or no growth during the first season. 

 If the winter is very severe it is quite pos- 

 sible they may die, as trees that are not in a 

 thrifty condition suffer, but the chances are 

 that they will live.
