,Extend mulch to edge of canopy dripline if possible
List the main equipment pieces that damage ornamentals -
ANSWER-Lawn
mowers and string trimmers are the main pieces of
equipment that damage
ornamental
plants
Site of injury is usually at the lower
trunk or stems

damage roots

Nurseries and the like have zero pest tolerance whereas
landscape plantings might have low tolerance.
Healthy lawns have a higher threshold than stressed, weakened

chosen nozzle
Reduced spray
pressure
Monitor weather
conditions

If water is acidic (pH less than 7) it can cause acid
hydrolysis
