Hi Mozza , I have been looking at some old Amateur Garden mags and came across an article on petunia hanging baskets by Kris Collins -gardening Editor. He says to cut them back to 15cm or so with a shears ( , sounds harsh ) but according to him this will get them back into shape for a second flush. This will take a few weeks ,but it will be worth it ( according to kris !) Oh , and he suggests a liquid feed after cutting back. Will be interesting to know if this works !
