Title: Coffee grounds as mulch into vegetable beds
Answered by: Barbara Medford

QUESTION:

Can you put too much coffee grounds as mulch into vegetable beds?

ANSWER:

Good grief! How much coffee do you drink? Seriously, we have used coffee grounds as a top dressing for rose bushes and added them to compost. We have no experience with using them on vegetables and just about all vegetables are heavily hybridized and/or non-native to North America, so out of the Lady Bird Johnson Wildflower Center area of expertise. We found this article from simplegiftsfarm.com on Coffee Grounds and Gardening. The fact is, coffee grounds are slightly acidic, and in our alkaline Austin soil, that is always a plus. 

From Seattlepi.com we found this site Give your garden a jolt with coffee grounds, which specifically says that you can't have too much coffee grounds mulch. And, it says that ground coffee is high in nitrogen, making it a very good mulch for fast-growing vegetables.That would appear to answer your question so, go on, have another cup of coffee.
