Hi John
Herons don't like any form of physical barrier. Try potted plants around
the pond. I use grasses in 15" pots. They kinda blend with the
pond........evergreen........low maintenance. I'm sorry for your loss of

fish.

A determined heron will penetrate almost anything - I cannot see potted
plants working at all round here !

Netting stands the best chance IMHO.

However I am interested in this suggestion from Jan

" Next
spring you can install a motion activated sprinkler and remove the net."

Could he please expand. - Many thanks

Regards
Pete
