Many cafes will give out quantities of used coffee grounds for your garden for free! Our local Borders does this and it is wonderful for the garden, esp. acid loving plants like azalea, lilac, hydrangea, etc. :) All you have to do is ask!

When planting vegetables, such as radishes, carrots, onions etc., try sprinkling some coffee grounds in the soil first and then plant your seeds. This should keep the worms away and is also a good fertilizer.

Don't throw away your coffee grounds or egg shells, instead as you turn the potting soil in your house plants, add the grounds and shells for healthier house plants. This can also be used in vegetable gardens for larger crop yields.

Laniegirl,t hank you for the site.It's a great source of information. Thanks for taking your time and answering my question.
I'm from Louisiana and I was wondering if used coffee grounds are good for the soil around my roses? I don't know enough about what roses need or what coffee grounds add to soil, so hopefully a more skilled gardener can shed some light on this.

I don't remember exactly what grounds add to soil (my mother also used tea grounds), but it is helpful to plants. If you want to use them around your roses, go for it!

I just put used coffee grounds outside around my plants. It acts as mulch and fertilizer. I even use the filters! You can hide the filter under leafy vegetation.
If youre fussy, you can always make a compost heap.
What are some ways that I can use coffee grounds without composting them?
By Karen from Luthersburg, PA
I just throw mine in the flower beds; don't even dig around them. I've heard they keep some bugs away. I know they are good for the soil.
I want to know the simple way to use coffee grounds for my home veggie garden. Thanks.

This is a tough one. My initial response is no, it is not a good idea to use the grounds from flavored coffee on your rose bushes. However, it really just depends on the ingredients. The main problem is that many flavored coffees contain added sugars or powdered creams to create certain flavors. This is especially true of instant flavored coffees. When used grounds or leftover coffee containing these ingredients is added to the soil, it can create an imbalance in the soil's chemistry that encourages insects and mold. And as you know, roses can be somewhat susceptible to mold problems as it is.
I don't know of any specific tests or studies to point you to, and I don't drink flavored coffee, so I can't speak from personal experience. If you decide to try it, I would recommend using only small amounts of grounds, and digging them slightly into the soil. I have heard some gardeners say that one of the added benefits of using regular used coffee grounds around their roses (grounds void of creams or sugars) is that the grounds actually work to keep insects away.

Not sure about the coffee grounds, but I heard that there's some enzyme or mineral in banana peels and onions that when you bury them in the soil around your roses that the roses will have stronger smell.

I have several small flower beds around my home. I also use a Lot of coffee. Are there any suggestions for using the grounds from coffee to nourish my dirt, other than building a compost pile? Small yard/ close neighbors leaves no room for smelly leftovers.

Where I used to work this girl drank black coffee and used to dump her "dregs" into this plant at the end of the day. It was the healthiest plant in the office. Then she switch to herbal tea. That poor plant was never the same. (09/15/2005)
I found some unused bags of ground coffee from several years ago in the back of a cabinet. I don't want to use them for brewed coffee to drink. I know there are many uses for USED coffee grounds, but do they have to be used? Can I use them unbrewed or will it be to acidic for the yard or garden?

Starbucks gives away bags of used coffee grounds free for the asking. Dump some on the ground of roses and other acid-loving plants and water. The coffee breaks down and feeds the plants and my roses have never been more beautiful or prolific.
