Home remedies used by gardeners
to deter slugs and snails are to be tested scientifically for the first time.
Researchers at the Royal
Horticultural Society are investigating whether the likes of egg shells and
copper have any effect in keeping slugs away.
The RHS is starting scientific
trials of five traditional remedies to see if they are based on science or
myth.
Dr Hayley Jones says the results,
available in the autumn, will help them advise gardeners with real confidence.
"It will really start to
tell us how well some of these barriers work," she said. "Is it worth
spending your time and money on them?"
Until now there has been no
formal study of the benefits of copper tape, sharp horticultural grit, pine
bark mulch, wool pellets and egg shells, compared with doing nothing, she said.
