I know coffee grounds can be used but can liquid coffee also be used in the gardens? I always have left over coffee and hate to use pour it down the drain.

I see no reason not to use it. Acid-loving plants would be where I would sprinkle/pour it, but perhaps you might want to dilute it if pouring it on/near a plant. I use all my coffee grounds around my azaleas, blue berry bush, and gardenia. I also incorporate it in my "custom-made" potting soil.

I also use left over coffee on my plants...Just add water to the pot and pour. I've even used it on my potted geraniums, and they've never bloomed better!

to ATP!

Jo - I always fill the coffee pot leftovers to the top and use it to water my plants. Even coffee grounds register neutral as testified by many pH tests to pounds of coffee grounds.

Not plant related, but I put left over coffee in the crock pot when I make pot roast.

Leftover coffee? I never heard of such a thing!

makes a nice rich gravy

@kqcrna, too funny!

I imagine it would go a long way to making a nice rich gravy! Hadn't thought of that!

Same here, there's no left over coffee at our place either. Gin that pot roast sounds good but doesn't it keep you awake?

Surprising that the coffee grounds are pH neutral. I wonder if the acid is brewed out into what we drink? If so then definitely dilute your leftovers before watering plants with it.
I think I need one of those analyzers.

Yes, dilute the coffee. I put the grounds into the compost bin. I read they aren't beneficial til some time later after they break down in the soil. And I feed my trees TEA, plain old brewed cooled off tea.

I also cannot imagine leftover coffee. If any left from the morning, it becomes nice glass of iced coffee later in the day.

I think the "come-away" message is: "If you are going to trash your left-over coffee/tea, why not put it in your compost/plant soil instead of just wasting it".
