Someone told me to pour cold leftover tea and coffee into the potted geraniums. So, is the caffeine supposed to give the plants more energy to grow flowers? I seem to remember hearing something about putting used tea leaves around under rose bushes, too… must look into this…

Well now, I produce coffee grounds like internet marketers produce spam. And I have three rose bushes that are doing better this year since I moved them into direct sunlight, but they could stand a boost. I’m going to try this today, to see what happens.
Thanks for the tip! I shall report back on my progress.
