We do not use poisons lightly and generally we don't. In this instance with this menace there is no other choice. Now when the fruit fly feed on that poisoned plant,(she likes the smell of it too)
They get drowsy and one can easily kill the lot with a spray. We have a vegetable garden. Some years we cope better with our geraniums to ward of fruit fly. This year Tomatoes were still quite infected, but we still had a good crop to harvest. Before we had this geranium everything was badly infected, eggplants, tomatoes, cucumbers strawberries, loganberries and also all fruits. Now at least with this geranium plant as helper we can cope to keep the fruit fly at bay.
Borage is such a beauty. Its blue flowers can decorate dishes and can also be eaten. The leaves taste of cucumber. I use the leaves in my herb salt. Once one has a Borage plant one has it forever. It seeds itself. It also looks nice in a mixed border. The individual plant doesn't last long but is easily replaced with a seedling.
Zinnia has self seeded. It has been mauled by Billy looking for grasshoppers. He is a great help in this regard. He catches them and carries them around and then lets them hop away! Great!
Tiny Parsley seedlings I have just planted. The stones, so Billy can't bury his bone!
Believe it or not: Peppers planted by an angry gardener or a lunatic will be hotter!
