Q.Fresh or brewed coffee grounds in veggie garden

Zone Novato, Caifornia | Anonymous added on June 13, 2020 | Answered

I did read your earlier article about fresh and used coffee grounds, and that never use the fresh ones on a tomato garden, thank you for that.

I need clarification on which veggies can use each type of coffee ground:

So, onions, carrots, bell peppers, jalapeno, snap peas, cucumber, tomatoes (can we use washed, brewed coffee grounds around a tomato garden or best to just not go there with that plant? )

The brewed coffee grounds can benefit any veggies and other plants, too. Just don't overdo or use it instead of your regular fertilizer. To be on the safe side, I wouldn't use fresh or used grounds on tomato gardens.
