use of coffee grounds in flower gardens
There was a lot of gardeners who use epson salts in their gardens. We have a Keurig coffee maker and buy the pods and I scoop out the used coffee grounds from the pods and save it in a plastic container. I am starting to leave the container top off as the coffee grounds got moldy with it left on..
I have added water in this container and shook it up well and poured it around my roses and hydrangeas and keep adding water and shaking it up. How often do you suggest I do this?
