Curious,
My Dad insists that used coffee grounds are good for laying in the garden as fertilizer. Only problem is they are there for an eternity. With my coffee maker, when it self cleans I have an undrinkable watery espresso I normally toss down the sink. And often times have coffee mis haps and toss cold any whatever as well.

What if I pour it onto my house plants? Anyone try my stupid ideas before I think them?

I'm not a botanist, but I don't see how it could hurt. I've heard of throwing worse watery mixtures on plants...plus, I vaguely recall hearing something about caffeine making houseplants grow quicker.

Your plants would probably hold out for a Latte and a blueberry muffin.

its a little trick to keep the ant away also . We have done it for years back home in the garden but never in houseplants.....

Mixed with grit, it is great against slugs too. All my coffee grounds go into the compost - and get mixed with all the other vegetable waste- so it is quite diluted. On house plants a little amount would perhaps be beneficial - but it would soon accumulate and take over!

My office plant is only watered with cold coffee. It's growing like Unkraut.

my mama says the same thing as your dad and i've been pouring actual coffee in at times as well. plants are growing and healthy so i don't think it hurts- and maybe it helps

What's Unkraut?

We compost our coffee grinds.

Apparently marder, cats and other animals don't like coffee grounds, so you can strew handfuls where you don't want them to go. Strewn on the ground, works to keep the cats and marders off my car.

One Google source says: Coffee grounds are often used in composting and are a great source of nitrogen. Unfortunately, most houseplants are not in an environment that is conducive to the breakdown of the coffee grounds that is necessary for the nitrogen to become available. Houseplants are usually potted up in a soil-less mix that is sterile. This means that there are no bacteria or organisms present to decompose those grounds. What you will most likely get is moldy coffee grounds mixed in with your potting mix.

Another says: My uncle had a hibiscus that was watered with old beer( alcohol evaporated), cigarette butts and coffee grounds. It was lush and flowered all the time. When he quit smoking and drinking especially when they were about to have kids, the hibiscus died.

Weed. German saying: "Wächst wie Unkraut" - "Grows like crazy".

I haven't tried it on house plants, only in my garden of aromatic plants but surely once a month or bi-weekly it cannot hurt. I wouldn't put it on orchids though.

...yeah, try it on weed...

Adding caffeine to weed? Interesting.

If you love your coffee, I suggest that your idea would be too much of a good thing for your indoor plants, put the coffee grounds out in the green waste for composting instead (not down the sink).

If you are looking for other ways to use up excess coffee grounds - check out the suggestion list put out by Slowfood last year: http://www.slowfood.com/internationa...offee/q=4F296A

...seem to remember that coffee grounds promote earthworms in your yard and garden.

Careful, there are daft EU laws about this, see here.

You probably need to further clarify that...

What if the plants cannot sleep?!?!!? And become addicted so that you have to give them ever stronger coffee. Before you know it they'll be stealing Migros energy drinks from your fridge whilst you are out. This could be a disaster.

It is also good to pour down the drain every now and then. It will get all the crap out
