Coffee Grounds A Miracle Weapon

Coffee Grounds A Miracle Weapon

Coffee grounds a miracle weapon not only for us humans

Who does not know that, you make coffee and the coffee grounds end up in most cases in the organic bucket. Why not simply use the coffee grounds in a different way than just throwing them in the garbage. The coffee grounds are excellent as flower fertilizer or even as a deterrent to some animals that you do not necessarily want to have in the garden. Especially plants that prefer an acidic soil are very grateful for a small addition of this miracle product.

Coffee grounds contain potassium, nitrogen and phosphorus and can be given as fertilizer for rhododendrons, ornamental plants and azaleas starting in February.

An example

Our plants need a healthy growth, if the leaves are yellow, this is a sign that potassium is missing.

Tip: The collected coffee grounds should first cool, because a hot coffee fertilizer is not suitable for fertilizing. To avoid the formation of mold, the fertilizer should be spread out and dried well.


The finished fertilizer can be laid out directly on the plants or mixed with the soil.
Simply mix the “coffee” with water already and water only the trunk of the plant with it.
From my own experience: the ready-made fertilizer is not suitable for our houseplants. The pot root ball can not decompose the coffee powder. It starts to mold after a while and it becomes musty 🙁.

Another point cats, ants and snails.

The coffee grounds contain bitter substances and other ingredients that provide a very specific smell. This smell many cats, ants and snails do not like at all and stay away from the places where the fertilizer is scattered or put in small bowls.


Other ingredients in coffee powder stimulate even more the slime production of snails, which can be fatal for these little animals. The caffeine contained in coffee grounds acts as a neurotoxin in snails.

Whether all this is true for snails, ants and cats, I cannot say. We have very few such animals in our garden. Many swear by this “coffee grounds” method and others say that this is of no use at all. You should give each method a chance, only in this way you can find out whether this works in your own garden or not.
