Coffee on the garden.?

Coffee grounds will not hurt your garden at all. In fact they are a killer of snails. It has been proven that coffee has a chemical in it that is poisonous to snails and after contact or eating they can die within a couple of days. I would think it is just the same as using snail baits but more environmentally friendly. The other thing is used coffee grounds make an excellent mulch. They are acidic with a pH of between 3.0 and 5.0 making them superb for mulching rhododendrons, azalea and other acid loving plants. But this is if you put the grounds close to the root base. I tend to scatter mine over my existing mulch and not near plant root base. Also you encourage worms as they love coffee grounds (and lots of other yummy stuff too) and we need worms in our garden.

Coffee grounds are excellent for anything that likes an acid soil like rhodos, azaleas. I use unbleached coffee filters and just dump the whole thing under those bushes. I also get buckets of used grounds from places like Starbucks which keep them for gardeners and are free and put them in my compose bin to add to the mix. You would have to check with which vegs you are growing that like an acidic soil and those would be the ones that I would dig the coffee grounds into next to the row of vegs. Also you can put tea bags there. I also use left over tea and coffee into the soil or the compost.

Coffee grounds are good for the garden. Boost nitrogen and is good for acid loving plants like blueberries, azaleas and rhododendrons. Spread around these plants or add to the compost. Starbucks offers free bags of coffee grounds.

I doubt it would hurt I have used tea leaves on My plants and they thrive so coffee could be Ok I don't think anyone would know for sure.I am alive and I drink buckets of coffee.Also had relations (Don't wish to really let You know ) but they had to empty their own toilet and guess where they tipped it? Yep on the veggie patch hence why My mum never ate anything they ever gave us.Thanked them and when they left threw the veggies away.LOL

The actual caffeine in the coffee probably wouldn't very good for your vegetables. If it's not good for us or animals how could it be good for plants? I guess it wouldn't really do that much damage as your only using small amounts though.

the ground coffee is ground up beans, it is biodegradable so it is fine for your garden. I put the grounds in my compost heap all of the time and spread that compost around my plants.

Yes. My son did a science experiment and had 4 plants. He put coffee on one salt on another and on the other two he put sugar and finally watered normally. Over period of six weeks the one with the caffine did best.

Yes, a very good source of nutrients

Yes my grandmother used to do this.
