Hi All! We had a weird incident happen with our worms this past weekend. We have been putting a sprinkling of our spent coffee grounds on top of our worm chow for many months now as the worms seem to love it and it has definitely encouraged them to breed and eat more! This past weekend we started picking up large batches of spent coffee/espresso grounds from a local coffee shop which we added to our worm bins on Saturday. When we checked them the following day, all our our worms were avoiding the areas where we sprinkled the grounds. Many were trying to get the heck out of the bin altogether! I checked the temps and it was hotter in the middle (where the food/grounds were)-about 90 degrees (yikes!) than it was on the sides (84 degrees). We removed the grounds/food and cooled down the bins by adding some moisture. We have not had any issues in the past with our own spent grounds, so I'm wondering what could have caused this reaction? Too much acid (different coffee)? Any thoughts? We'd love to keep using the grounds from the Coffee Shop as it helps to reduce waste. Should we put the grounds through a composting process? There is a farm/nursery (Laughing Buddha) on YouTube that uses a mix of coffee ground/wood mulch as his bedding for his worms (composted, of course). Would love some feedback on if and how you all use coffee with your worms. Thanks and have a great worm day!
