So many of us are on a tight budget these days. The money for plants, potting materials, and fertilizer may not be reachable for all. While you still have to buy plants and soil, there is an alternative to fertilizer. It involves something most Americans use every day and have to dispose of regularly. It's your used coffee grinds!
Coffee grinds contain useful amounts of phosphorus and potassium, are a low-level source of nitrogen and also contain minor amounts of calcium, magnesium, copper, and other trace minerals, carbohydrates, sugars, some vitamins, and some caffeine. They are great for acid loving plants like tomatoes, roses, azaleas, blueberries, camellias, avocados, some fruit trees, and evergreens.
There are three different ways you can use grounds as your fertilizer:
1.Mix your grounds with water. You don't need a lot of grounds, it's really a 1 to 5 ratio of grounds to water. Let the mixture get to air temperature and then you have home made liquid fertilizer.
2.They can be dried in your oven, adding a coffee smell to your home and creating a dry fertilizer. After dried you can sprinkle them at the roots of your plants. You may be wondering, why dry used coffee when you could just use fresh grounds? Dry, unused grounds contain too much acid and nitrogen. So be sure to use them first!
3.And lastly, you can mix your grounds with soil to plant in. The coffee filled soil will attract more earthworms than regular soil. Earthworms are great for your soil. Make sure that you break up the soil before you place it on top, that way it won't mold.
You can also add the grounds to your compost pile to give it a great boost. If you are like most Americans, you drink coffee every day, so acquiring grounds is no problem. But let's not assume here. If you absolutely hate coffee, you can ask your local coffee joint for theirs. May give them away like Starbucks. If they try to make you pay, walk away! There are plenty of coffee houses that will give them to you and you shouldn't have to pay for what they would deem trash anyway!
