104 PESTS AND SPEAYING. 



Water supply is everything to a garden, and it 

 will be noticed in the plans of gardens in this book 

 that many of them bave ponds, which are included as 

 much for utility as beauty. 



Water for all plants is best exposed to the sun for 

 some hours; it brings it up to the right temperature, 

 and the plants benefit far more from it when thus 

 applied. A tank of water should always be ready, and 

 buckets can be filled from it when desired ; a container 

 or tank with a pump and lance attachment is best, for 

 the latter can be easily taken off. The Haven En- 

 gineering Company, of Goudhurst, Kent, make a 

 speciality of these lines, and have some very useful and 

 practical models at most reasonable prices. The ad- 

 vance in spraying machines and insecticides of late 

 years has been very great, and the Rose grower can 

 easily satisfy his requirements. 



The Greenfly or Rose Aphis is by far the worst 

 pest of the garden, and once it infests a tree it does 

 great harm. 



The thumb and finger will clean a shoot, but 

 nothing short of a good insecticide will save the situa- 

 tion when aphides are well established. 



A good spraying once a week when the trees are 

 coming into leaf and buds are forming will not only 

 kill the various insect pests, but it will ward off the 

 attacks of others. Caterpillars of various Moths are 

 hard to discover, but a good spraying will soon find 

 them out, and will kill them. 



I have noticed that The Rose Leaf-cutting Bee 

 will cease its attacks on a tree that is sprayed, and 

 that other sturay enemies of the insect world will go 

 elsewhere to lay their eggs when they find their food 

 polluted with insecticide. There is little to fear from 

 the majority of insect pests if only you spray your trees 

 occasionally and hand-pick the maggots early in the 

 year. Much depends upon the season, some years 

 being worse than others for all insect pests. As a
