Why use spent coffee grounds in the garden?

Hi there, It should not be used on alkaline soil, but if you have acid soil it will be fine to use. How about sticking to fertilizers to be on the safe side. 1.

Coffee Grounds are good for the soil because they are very coarse and decompose slowly in the soil and helps to aerate the soil. Egg shells are also great to use as well.

Not very good for MOST flowering plants---CAN slow or stop the flowering process, as the grounds help with leaf & stem growth. Better for GREEN OR LEAFY PLANTS & BUSHES. Something to do with the acid levels but I'm not that technical--just know that I put it on my tomatoes & they formed NO fruit.

I heard that it is good for roses. It helps them grow .

It's an organic fertilizer.. It would be better though to let it turn into compost first. Microorganisms will break it down into nutrients for the soil. Also don't just limit it to coffee grounds. Use fruit and vegetable waste as well such as banana peels, carrot tops, etc. Basically any part of a fruit or vegetable that you don't use, or ones that have gone bad. One major benefit of composting is a way for you to stop using your garbage disposal as it really isn't necessary. If you continue to use it it will just cost you more money to have to constantly get it unclogged. Stop using it and put all that stuff in your garden

sulfites i believe

compost every thing vegetable for a great garden

yes good as mulch in the soil. very common practice.

Coffee grounds enrich the soil, & when mixed into the soil, makes it less subject to compaction... which makes it a better environment for earthworms & for the organisms that keep a plant healthy. The earthworm's movement within the soil also help improve drainage, which keeps the plant roots from rotting. Put a layer of coffee (grounds) on the bottom of your pile to attract earthworms. http://compost.css.cornell.edu/worms/faq.html A lab test analysis showed that: "the grounds provide generous amounts of phosphorus, potassium, magnesium, and copper. They also release nitrogen into the soil as they degrade." The full report is here: http://www.sunset.com/sunset/garden/edible/article/0,20633,1208232,00.html It's good for acid-loving plants, like Roses, Azaleas & blueberries. I lightly sprinkle the grounds around the base of these plants to deter slugs, also. You can scratch it into the soil so it doesn't compact when it has accumulated. It also helps the soil retain moisture. Since the grounds are acidic, when using around non-acid loving plants, mix a tablespoon of garden lime into a five pound bag before you dig them into your garden or just put the grounds on the compost pile. "In the garden, mix at a rate of five pounds per three square feet. For composting, mix at a ratio of five pounds per three cubic feet of yard." http://www.walterreeves.com/tools_chemicals/article.phtml?cat=22&id=86 Rose gardeners reported coffee grounds make their roses larger & more colorful. Adding it to compost piles increases nitrogen balance. Encircling plants with coffee grounds & eggshells makes a barrier to repel pests. http://www.associatedcontent.com/article/181467/coffee_grounds_and_your_garden.html Good luck! Hope this was helpful.
