My petunias in my hanging baskets have been flowering well, and my
wife and I have deadheaded them regularly to continue flowering.
However they are starting to get a bit leggy so I was wondering about
trimming them back.
I recently trimmed back my pansies (winter ones that have flowered all
through spring and early summer) and they have taken on a new lease of
life. Will petunias behave the same way?

Cheers
