For use with RA-PID-GRO on Lawns 
and for Foliage Feeding we recommend 
the TRI-CON Lawn Fertilizing Unit. 
The new TRI-CON method soaks the 
RA-PID-GRO fertilizer in as you apply 
it. Gardeners everywhere acclaim it as 
the best method ever devised for even, 
safe, effective distribution. Puts the 
stimulating, soluable material directly 
where it is immediately available. Em- 
bodies new principle in fertilizer appli- 
ers. No mussy pre-mixing is necessary. Fertilizer placed in jar ac- 
cording to manufacturers instruction in dry, concentrated form; 
comes out in liquid form, automatically, properly mixed with plenty 
of water. 
After applying fertilizer, the patented reversible cap instantly 
converts gun into pistol grip hose nozzle. Sprinkler base also furnished 
for use as stationary sprinkler. 
The ratio of the amount of water to the fertilizer remains the 
same, regardless of water pressure. The pressure does not affect the 
strength of the solution. It does control the speed with which the jar 
is emptied—the higher the pressure the faster it will be used. 
The strength of the fertilizer solution does not vary with the 
amount left in the jar. 
It cannot be used for insecticide spraying because it delivers 
too much water and solution would not stick to leaves.
