Do you put coffee grounds in your garden?


Recommended Posts

I'm a novice vegetable gardener and I have heard of people doing this. Also, I have heard of sprinkling crushed egg shells around the plants. Is this really going to help my tomatoes, green beans and water melon? Or are these old wives tales?

Some plants like an acidic soil not alkaline. One is acid the other base chemically speaking. Rhododendrons, azaleas and blueberries love this. However there are other plants that do not thrive on acidic soil. Here is a link explaining the why and how. http://www.extension.umn.edu/info-u/plants/bg497.html My holly bushes love coffee grounds not my rose bushes. I took our soil to the county extension office and they told me what soil amendments were needed. Happy to help and call your local extension office for any other assistance as they are usually delighted to help and eager to encourage novices.

We usually put the coffee grounds and eggshells in our compost. However, I have found that both crushed eggshells and coffee grounds are pretty effective snail deterrents, so if you've got a slug or snail problem, you can sprinkle them around your plants or your garden area.

Eggshells add calcium to the soil. Tomatoes really benefit from the calcium. Lack of calcium can cause blossum end rot. But there is some debate about how much calcium eggshells will actually help. The shell has to breakdown and allow the roots to take up the calcium. Some people will put an egg shell in the hole when they plant tomatoes. We just put them in the compost (as many others have suggested).

 

We don't drink coffee so have not coffee grounds, but I would put them in the compost if I had them. Again there are benefits of putting them around individual plants, but you'll have to figure out which plants and how much. You can make soil have too much of one nutrient or acidity and so we find that composting keeps everything well balanced.

we definitely put coffee grounds in the compost, and have even heard of some people going to starbucks to ask for discarded grounds to add to their compost. it's organic material, and all organic material besides meats and bones can go in the compost.

You betcha!

 

For what it's worth, the coffee grounds themselves aren't what actually nourishes your soil. Microbes, bugs, and earthworms eat the coffee grounds and leave their contribution in your soil. That's the stuff the plants want. :D

 

Also, coffee grounds will not change the pH of your soil. Any acid in the grounds leaves during the brewing process. Studies show that the grounds are pH neutral.

 

I get bags of grounds at Starbucks. We spread them thinly over a bed and around plants, and dump bags of them in our compost. Just go in and ask for coffee grounds for your garden. I guarantee you aren't the first person to ask.

 

One caution...I do think coffee grounds around tender transplants are too 'hot.' The process of decomposing sucks up nitrogen in your soil, so your plants will starve for a while. Big plants, shrubs, and trees can handle this because their roots cover more area. Small tomato transplants don't do as well.
