I was given a few gallons of free coffee grounds from Starbucks to put on my yard. A week ago I unloaded the massive amount I was given on to all of my plants. Most of the flowers are acid lovers. My begonias have been getting brighter and growing faster. You can also put coffee on your yard and other plants that are not acid lovers. Simply use less or dilute it. Earth worms love it and earth worms make great dirt for your soil. Our yard smelled like coffee for days. It was awesome. Head on over to your local Starbucks and ask for some free grounds.
