THE CANADIAN HORTICULTURIST. 



The Codling Moth is one of the worst 

 enemies of the apple grower, and every year 

 the percentag-e of wormy apples in untreated 

 orchards is increasing. We have known 

 instances where fully one-half of the crop 

 was wormy and the affected apples were 

 otherwise the finest of the fruit. Since only 

 about thirty days elapses between the de- 

 position of the Q^^ and the appearance of 

 the adult moth, it is evident that we have 

 in Canada at least two broods in a single 

 season, and farther south there are three 

 and sometimes four. 



Now a man with a small orchard will try 

 and keep down this worm by poultry and 

 stock, but for the large orchard, faithful 

 spraying with Paris green (4 ounces to 50 

 gallons of water) is about the best treatment. 

 It is an expensive job, and for this reason 

 many neglect it and their orchards become 

 breeding places of worms to ruin their neigh- 

 bor's fruit. When neglect of spraying is 

 general, the work of keeping one's own or- 

 chard clear is almost hopeless, but if the 

 work be at all general, one may spray with 

 the more confidence of success. The first 

 spraying should be within a {^vj days after 

 the blossoms fall, and should be repeated 

 several times at intervals of about a fort- 

 night, if one is determined to succeed. 



Shelter For Straw- 

 berry Plantation.— On 



page 126 some refer- 

 ence was made to the 

 beneficial results to 

 plants from night shel- 

 ter, and now we notice 

 in the April number of 

 the Southern Fruit 

 Grower, a record of 



excellent results from covering a strawberry 

 plantation with thin muslin, from the time 

 the berries begin forming until picking time. 

 Protection of this kind was estimated to 

 increase the crop fully fifty per cent., to 

 largely increase their size and to make them 

 earlier in ripening. Notwithstanding that 

 the cloth hung limp and close over the 

 blooms, yet pollenization was absolutely 

 perfect, because the confined air, laden with 

 pollen, reached every blossom. 



Possibly this protection more nearly re- 

 sembles nature's wild strawberry garden, 

 where the vines have semi-protection from 

 grass and wild plants, in fruiting season. 



in fastening the cloth, stakes were used, 

 projecting six inches above the ground, 

 through the upper end of which a gimlet 

 hole was bored, and a six inch piece of 

 small soft wire run in, of which one end was 

 twisted about the stake, and the other bent 

 into a hook to hold the cloth, set one and 

 one-half yards apart in rows less than three 

 feet apart.

Canker Worm. — This is a troublesome 

 enemy of the apple tree in some sections or 

 Ontario, and if neglected, will quickly in- 

 crease to such an alarming extent as to 

 threaten the life of the trees. The first 

 evidence of its work is the perforation of the 

 leaves with small round holes, which grad- 

 ually increase in size until nothing but skel- 

 etonized leaves remain, and the trees look 

 as if scorched by fire. 



These worms were very bad around Bur-
