To keep your potted flowers and vegetables growing really well, take a plastic jug or bottle and fill it with water and add a few tablespoonfuls of used coffee grounds. Let this stand a few days then use it to water your plants every other time you water. This sounds silly, but all my plants love it and they grow great. Plus, you recycle your old coffee grounds instead of throwing them into the trash.

Don't add your coffee grounds to the landfill. Your garden will appreciate them much more! Sprinkle coffee grounds around your plants and trees. You can also compost coffee grounds. It's easy being green.
Note: Coffee (and tea) is toxic to dogs, so please be sure to not sprinkle the grounds where your curious canine can eat them.

Can coffee grounds from flavored coffee also be used? (01/05/2008)

Use left-over coffee from the pot to water your houseplants. It is great, natural plant food. African violets love it. If there is just a little coffee left, add enough water to get them all watered. Keep coffee black, no cream or sugar, ha! Phyllis (03/31/2009)

I put the coffee grounds from my morning pot of coffee on my azaleas and my hydrangea plants.

It used to be possible to get coffee grounds free from Starbucks. They were glad to get rid of them and had them pre-bagged for people to help themselves. They are also supposed to be good for keeping cats from fouling around your plants. We don't have a Starbucks locally so I don't know if they still do it. We used to take them home when we were on holiday :-) (06/13/2009)

I know coffee grounds are good for the garden, but are they also good for indoor plants?
If coffee grounds are already moldy can they still be used outside? What can be added to the grinds so they don't spread the mold?
