Do not wait until insects appear to start spraying. Damage has 
already been done to your garden by that time. Spray in the Spring 
and at regular intervals thereafter, and save work and worry later 
on. With spraying made as easy as watering your garden, it will 
be fun, not work, to guard against the insect enemies, and your 
garden will repay you in greater beauty and luxuriance.
