use of coffee grounds in flower gardens

pippi21(Z7 Silver Spring, Md.)July 26, 2013

There was a lot of gardeners who use epson salts in their gardens. We have a Keurig coffee maker and buy the pods and I scoop out the used coffee grounds from the pods and save it in a plastic container. I am starting to leave the container top off as the coffee grounds got moldy with it left on..

I have added water in this container and shook it up well and poured it around my roses and hydrangeas and keep adding water and shaking it up. How often do you suggest I do this?

As often as you want, really. Whenever your plants need watering.

Coffee grounds are a caffine jolt for your plants...they put nitrogen in the soil which is good and if there are earth worms those little boogers just love them. coffee grounds also if used too often could turn the soil to acidic and could cause a depletion of nutrients...they can burn your plants during hot summers especially if not watered in well and depending on the type of plants. I use mine on things like hydrangea, bouganvillea, roses any of your acid loving plants maybe every 3-6 months ....too much though it is kinda like eating ice cream all the time, it could one day make you sick (Sometimes a good thing can be too much). Coffee grounds are a soil admendment not fertilizer. But it sounds like you use a very minimal amount just make sure the coffee get mixed in the soil well and watered. How about composting it? 1part green (coffee)(grass clippings) to 2 parts brown
(dead leaves) I hope this helps....HAPPY GARDENING :)

Sand....the pH of used coffee grounds is quite close to the mid-6s. The acid is in the coffee cup!
