Air Pollution Harms Holly Plants

 

 

If you grow holly plants be aware that they are particularly susceptible to air pollution. Ozone in particular.

Scientists at Staffordshire University in the UK conducted experiments exposing holly to ozone levels that they are exposed to in the summer. The tested plants produce fewer leaves and shed more leaves as well. Ozone also affected the plants hardiness to withstand cold winter temperatures.

Ozone forms when ultraviolet light from the sun combines with hydrocarbons and nitrogen oxides emitted by cars, power plants and industrial sources.

Ozone pollution is so serious, especially in cities, that ozone alerts are broadcast to alert people with respiratory illnesses to stay indoors.

Ozone affects holly plants grown in the United States, Canada and Europe.
