Some cafes are giving away coffee grounds to use as garden fertilizer.
I did a search of the internet and as usual found conflicting information. Some say coffee grounds are useless, same say they are great for acid loving plants. We bought a weigela which has really wilted in a week so I'll plant that with the coffee grounds we got yesterday at lunch to see if they can bring the plant back to life.
And an added bonus is that grounds are meant to be a cat deterrent!
