Use egg shells and coffee grounds for a good supply of calcium and N.
I wouldn't rely on coffee grounds for nitrogen, but as a free mulch they're pretty good. They help hold moisture and keep the top one inch of soil from getting to hot in the summer. Best of all you can go to any Starbucks and ask for spent coffee grounds. They give them away free to anyone who needs them for their garden.
A real gardener is not a man who cultivates flowers; he is a man who cultivates the soil. Organic gardening is based on knowledge and techniques gathered over thousands of years, using sustainable and holistic approaches.
Only as it degrades..
A lab test shows that coffee grinds provide a generous amount of phosphorus,
potassium, magnesium, and copper. They also release nitrogen into the soil as
it degrades throughout the year.
either way its beneficial to the grow. If your looking for other organic sources for nutes try ash and egg shells
Just letting you know so you know.
Not being a douche bag![]()
Any idea how long it takes to degrade? Do you grow with coffee grounds? Starbucks has them for free and I'm going to have to amend my soil. I think my kale greens are reaching the end of their life (I've harvested 3 times already) and I am going to re fresh the soil in their spots before mid summer for my Fall veggies.
I assume that everybody treats people like they like to be treated. So don't be mad at me because you treat people like an asshole.
