We have a dreadful, widespread infestation of Vinca, which years of rooting out by hand has barely touched. I think the time has come to start trying a weedkiller of some sort, but the infestation is in a rockery and round the base of large, established plants such as rosebushes, oleanders, wisteria, juniper and hibiscus. I doubt now is a good time of year to start, but I should like to be prepared to attack new growth as soon as it rears it's head in spring. Does anyone have any good advice as to which weedkiller and method of attack?
