VIOLA & LOBELIA & GARDEN PESTS

Last year, and the year before, when I grew violas in my trough, under my north-east facing kitchen window, they succumbed to mildew.  This year, I have planted them in individual pots so that they can be moved, if necessary.  I think that crowding of plants is one of the things that encourages mildew, so we'll see.  I've also potted up a bigger tub.  Truth is, I went a bit mad and bought so many lobelia plants and violas that I didn't know what to do with half of them.  That's what happens when you cannot count.  I thought the plastic trays of lobelias held six plants when, in fact, they held nine!

By the way, not only have greenfly invaded my roses by the thousands but also I have noticed an awful lot of wasps around.  Killed the greenfly with a systemic pesticide and killed the wasps with my slipper!  Unlike bees, I cannot think that greenfly and wasps benefit my garden in any way at all.  So adios pests.
