Starbucks gives away bags of used coffee grounds each day. It's part of a recycling program called Grounds for your Garden. This bag had a gallon and a half of fragrant grounds and today, my garden is buzzing with caffine. During the bewing process, most of the acidity is removed, leaving used grounds with an average pH of 6.9 and a carbon-nitrogen ratio of 20-to-1. This important to know because it determines how to use it in the garden.I could have added it to my new compost tumbler, but I already had a lot of "green" in the tumbler, so I didn't need any more. I decided to use it as a side dressing to the brambles, specifically to the blueberries and blackberries.
The blackberries need a soil pH level of between 6.0 and 6.8, so this isn't the perfect side dressing, but it's better than the nothing that I've been using for the past few months.Want to to know more about soil pH in the South Florida Garden? Here's one of my archived articles:
