When some people are already packing up their shovels and leaving the dacha, others are making one simple move and in the spring they get clean beds without fighting weeds. The secret is simple: breakfast leftovers that are usually thrown away.
Coffee grounds gently suppress the germination of weeds, loosen the soil over the winter, attract earthworms, and at the same time are absolutely safe for cultivated plants, even if garlic or winter dill are already planted in the beds.
You need to collect the grounds from 5–10 cups of coffee, dry them well and scatter them over the cleaned beds in a layer of 3–5 mm. Treat especially carefully the places where wheatgrass, woodlice or quinoa were rampant in the summer. The top can be covered with straw or chopped leaves. This way the effect will be even stronger.
By spring, the grounds will partially rot, enriching the soil with nitrogen and organic matter, and the weeds will either not sprout or will be so weak that they can be easily removed by hand.
Autumn showers can wash away the top layer of soil, especially in empty beds. To prevent this from happening, do not leave the soil bare after harvesting. Even if you don't use coffee grounds, simply cover your garden beds with a thin layer of grass clippings, shredded leaves or straw. This will protect the soil from erosion, retain nutrients and provide comfort for beneficial microorganisms all winter.
Question and answer:
Do I need to dry my coffee grounds before using them?
Yes. Fresh, damp grounds may become moldy or cakey. It is better to dry it in a thin layer on a newspaper or under a canopy, and then store it dry until the autumn processing of the beds.
Do coffee grounds harm garlic or winter dill?
No. When used correctly (thin layer 3–5 mm), it does not damage even young plantings. On the contrary, it improves the soil in which they overwinter.
Can I mix coffee grounds with leaves or straw?
Yes, and even recommended. Straw or shredded leaves on top protect the grounds from weathering, retain moisture and create a multi-layered mulch that works better all winter.
