If coffee grounds are good for your garden, would the leftover coffee also be good too?

If you have leftover coffee you are doing it wrong.

Some high-powered garden nerds say coffee grounds aren't good for the garden (BBC4 GQT for example), but I have always had good luck with them and when added to vermicompost the worms liked them. But those were Seattle worms now that I think of it.
The occasional cup of coffee is unlikely to hurt your plants...sans cream and sugar. it's a proverbial drop in the bucket.
Of course, I've never tried your
I find myself most amusing.

Everything in moderation Whistling ...left over coffee grinds to spread around the whole garden. I would take the coffee pot, with left over coffee, and fill the pot with water. Then take the diluted coffee and everyday would pick a different garden plant outside to water. Everybody smiled.

JBarstool Rolling on the floor laughing Rolling on the floor laughing Rolling on the floor laughing true no one should ever have leftover coffee!

May joy and happiness be at your door!

Well, diluted and spread around like a stale beer would be ok, but I think it depends on your soil ph as to damage it (MIGHT) possibly cause. In massive quantities nothing is great for us or plants, therefore the 'moderation in all things' approach.
So many roads to take, choices to make, and laughs to share!

Starbucks gave me more coffee grinds than I needed but they are free. When I asked they said sure if I would go around to the pack they would put it in my trunk. When I got home I did not know they had but 8 35 gallon garbage bag of coffee grinds in the trunk.LOL I did end up using it all though.

If you have plants that need acidic soil it is good. I use them around my Rhoddies and Azalea bushes and I could see the benefit because they started performing spectacular.

I have tried growing a few tomato plants only with coffee and they are currently in the same "growth state" as the ones grown with water Smiling

You know that last bit of coffee that always seems to be left in the carafe? Don't just pour it down the drain -- you can use it to fertilize your container-grown plants. Coffee grounds (and brewed coffee) are a source of nitrogen for plants, which is the nutrient that produces healthy green growth and strong stems. Coffee also contains calcium and magnesium -- both of which are beneficial to plant health.

To use coffee as a plant fertilizer, you'll need to dilute it. It should look like weak tea -- see the photo for an example. If you aim for about 1/4 coffee and 3/4 water in your mixture (depending on how strongly you brew your coffee), that's about right, but you don't have to be fussy about it. You can use coffee fertilizer on your potted plants, houseplants, or in your vegetable garden. Coffee and coffee grounds can be acidic, but since we're diluting it so much, that's not really a problem unless you're watering the same plant with it every day.

A good rule of thumb is to feed and water your plants once a week with a weak coffee solution. They'll appreciate the additional nutrients, as well as the water.
