  • Applying organic fertilizer to potatoes

    Created by deltaqueen on

    Hello –

    I am a new organic gardener and have been using products found in the kitchen to do so.

    I’ve been told that potatoes thrive in an acid soil so I’ve added coffee grounds to my soil 2 weeks before planting. Now it is time to fertilize my potatoes again and I want to know what is best. Should I add more coffee grounds or purchase a store bought organic mix??? And what would that be that is spud friendly?

    I’m happy to hear you’ve taken a liking to growing your own potatoes! Coffee grounds were a good start to getting them up and going, but I think a simple layer of organic compost should do the trick. I would suggest testing the pH of your soil just to be sure that you are keeping it in a friendly range for your plants before fertilizing.

    Potatoes shouldn’t require too much fertilizer after planting if a good base layer was set to plant in. Feel free to check out our pages on growing potatoes and where to buy our organic compost here:

    While doing a little more research, I found a website with a gal who uses coffee grounds before planting and the progression she takes, along with another page that describes how to use coffee grounds in the garden with instructions.

    Her experience: https://groundtoground.org/2010/12/10/potatoes-and-coffee-grounds/
    Coffee grounds as fertilizer: https://groundtoground.org/2010/07/05/ground-to-ground/

    Good luck!



    I am using the Humboldts Secret Golden Tree organic fertilizer for my potato farm and flower gardening. It has the main feature that it provides explosive growth and will serve as the rescuer for the dying plants. Try this product once; you can get the result.
