For those of us who have our morning coffee, the grounds add up. In fact Northwest Landfills estimated over 3 million pounds of used coffee grounds come to their landfills every year. If we could find a practical use for all those grounds it seems like there would be a better use.
There is still some controversy about putting straight coffee grounds into your garden or around the plants. Plants that grow well in high acidity can handle straight grounds. Other plants may do better with a composted version of the grounds. Whatever you are doing if you have a garden, plants or a compost pile the coffee grounds should never end up in the landfill.
Why are coffee grounds so good for plants? Coffee contains several things that help plants to grow into healthy specimens. Some of the most important are tannic acids, nitrogen, potassium, and phosphorus. These same ingredients will be listed on labels of fertilizers that can be purchased at the local garden shop as well. So you can save yourself some money by using coffee, and coffee grounds to make your own concoction.
Some of the plants that may be found around the home that particularly good results with high acidity are mountain laurels, blueberries, cardinal flowers, cranberries, pecans, azaleas, ferns, spruce, lupines, camellias, gardenias, butterfly weeds, heathers, yews and rhododendrons. These plants can handle dried grounds sprinkled on the top soil for a slow-release nitrogen. They can also be watered with diluted coffee and a fertilizer and enrichment product.
Using a composting pile to have great soil is a good plan. Tea bags and coffee filters compost rather quickly as well. So feel free to toss the whole kit and caboodle in the pile with plenty of leaf mold to heat up the process. Each year till compost into your garden soil to keep it refreshed. Vegetables take a lot of nutrients from the soil and put them on the table. They need something to work with every year.
Many coffee drinkers take the coffee that may be left at the bottom of the pot and cool it and add it to the room temperature water they use to water house plants. It serves as a liquid fertilizer.
If you are interested in how much coffee grounds can help growth go to your local science fair. It seems to have replaced the “what kind of music do plants like” project. There are some very convincing results. Why not stop by encourage the students and get some tips?
