Coffee grounds are an ideal fertilizer in the garden and also improve depleted potting soil and compost. The all-round talent can also help against snails.

Coffee grounds are produced regularly, but mostly end up in the garbage. It can mainly be used as a fertilizer in the garden, because it contains a lot of valuable ingredients such as potassium, nitrogen, phosphorus, tannic acid and antioxidants. These are nutrients that can also be found in commercially available fertilizer products.

Let dry before use

The basic requirement for use is that it is always well cooled and dry, as damp coffee grounds can easily go moldy. To do this, put the coffee grounds in an open, wide container and allow to air dry.

Fertilize with coffee grounds

Rhododendron is happy about the gift of coffee grounds.

Coffee grounds have a low pH value and are therefore particularly suitable for fertilizing plants that need acidic garden soil. Ornamental plants include, for example, hydrangeas, rhododendrons and camellias. Coffee grounds fertilizer is also suitable for crops such as cucumber, tomato, zucchini or blueberries and strawberries.

The nitrogen contained in the coffee grounds ensures strong leaf growth, while phosphorus stimulates the formation of flowers and fruit ripening. Potassium is important for the cell structure and the stability of the plant. Only seedlings do not tolerate caffeine well. To fertilize, simply work the coffee grounds into the ground, for example with a rake.

Use in irrigation water

Coffee grounds neutralize calcareous irrigation water.

In the case of very basic soils and calcareous water, a spoon or two of coffee grounds in the irrigation water can work wonders. It neutralizes the pH value and at the same time fertilizes the soil. Coffee grounds, on the other hand, are not well suited for watering indoor plants, as mold can form over time. Mixed with water at a ratio of 1: 1, but cold coffee can be used once a week to water indoor and balcony plants.

Coffee grounds improve compost and potting soil

Coffee grounds are also used well on the compost. It accelerates rotting, enriches the soil with nutrients and provides food for earthworms. So that no mold forms, sprinkle the coffee grounds on the surface and put the filter in separately.

Depleted potting soil can also be improved with coffee grounds and then reused. To do this, mix equal parts of the old soil with compost and fold in small amounts of the coffee grounds. However, if there is too much coffee in the soil, mold can easily form.

Coffee grounds can protect against snails

Snails don't like caffeine. The coffee grounds are therefore suitable as a barrier that can simply be sprinkled around the vegetable patch. However, this is not the case in all species. Depending on which type of snail is threatening the lettuce, it is definitely worth a try.
