THE CANADIAN HORTICULTURIST. 



iOTii AiP coaaemt; 



Canker Worms are at work, and must be 

 killed while small, with Paris green spray, 

 three ounces to forty gallons of water ; or 

 with the Kedzie mixture described on page 

 184. 



Codling Moth and Plum Curculio should be 

 fought at once, and the same spray advised 

 for Canker worms is useful if applied as 

 soon as petals fall. 



Borers are often very troublesome in an 

 apple orchard that is not growing vigorously. 

 There are two kinds, the Round Headed 

 and the Flat Headed ; and the latter is the 

 more common in Ontario, The eg-gs are 

 deposited in June and July, under the loose 

 bark ; and the young- worm soon eats its 

 way through the bark, and sometimes 

 girdles a small tree completely. Washes of 

 soft soap, reduced to the consistency of 

 paint by the addition of a strong solution of 

 washing soda in water applied once in June 

 and in July, is a preventive. If the insect 

 is already established, nothing will do but 

 the knite. 



The Peach Tree Borer, if neglected, in- 

 creases in the orchard to such an extent that 

 the trees may be almost ruined by its gird- 

 ling them. The eggs are deposited on the 

 bark just at the surface of the ground, in 

 the summer season, and the young- larva 

 works its way downward, devouring- the 

 bark of the root, and causing an accumula- 

 tion of gum, which often forms in a thick 

 mass around the base of the tree, a sure 

 guide to the presence of this borer. When 

 once it is in the root, the only thing- to do is 

 to dig away the earth a little, and to search 

 it out with a knife and destroy it. One of 



the most convenient preventive measures 

 is to heap fine earth about the trees early in 

 June, and this will prevent the borer from 

 reaching his chosen place for oviposition. 

 Some years ago we had a hard fight with 

 this insect, but routed it entirely in the way 

 above described and have had no return of 

 it since, worth mentioning. 



Apple Scab, which has wintered on the 

 bark and old leaves, is now sending out its 

 young spores to fix themselves upon the 

 new leaves and the young fruit. Spraying 

 with the Bordeaux mixture, the preparation 

 of which was described on page 103, March 

 number, will largely prevent the scab from 

 affecting the fruit, if it is kept well whitened 

 with the mixture. Some kinds are especially 

 subject and should be sprayed faithfully, viz: 

 Fameuse, Fall Pippin and Early Harvest. 

 Some other kinds, such as Baldwin, Ben 

 Davis and Duchess, are seldom affected. 



The Deutzia Lemoinei, sent out this spring 

 to our members, is a valuable acquisition and 

 when it blooms will be much appreciated by 

 all. The bush is quite hardy, and reaches 

 a height of about three feet ; it is a very pro- 

 fuse bloomer, making- it a very fine orna- 

 mental shrub. The flowers are pure white, 

 with yellow stamens, larg-er and more showy 

 than those of the well known but smaller 

 and more tender variety D. gracilis. There 

 are several other varieties, as rosea, scabra, 

 crenata, but none so desirable for Ontario 

 erardens as Lemoinei. 



Oriental Markets for Fruit. — No one can 



foresee the unlimited extension of which the 

 export trade in North American fruits is 

 capable. The obstacles that have hitherto
