We buy a lot of useful things in stores for a lot of money, even though we don't have to. In many cases, fertilizers are part of this, because coffee grounds, for example, contain all the important ingredients for garden and potted plants. However, you should not immediately run into the garden with the filter bag in hand - some additional information is useful before fertilizing.

Coffee grounds should only be used sparingly for the boxwood

Coffee grounds as a natural fertilizer

The main nutrients that every plant needs are

  • nitrogen
  • potassium
  • and phosphorus.

Coffee grounds contain plenty of these, as well as other minerals and trace elements. Of course, you shouldn't throw this treasure in the trash can, but rather use it for your plants. However, do not fertilize them with coffee that is still wet, as this molds very quickly. First dry the powder carefully and keep it in a screw-top jar or similar. Discard it as soon as it smells even faintly of mold.

Is coffee suitable for fertilizing Buchs?

In principle, dried coffee grounds are also suitable for fertilizing boxwood. The only problem is that the agent also reduces the pH of the soil. Over time, this becomes sour - and the lime-loving Buchs does not like that at all. For this reason, you should avoid using coffee as a fertilizer or mix it with neutralizing stone powder. Plants growing on acidic or peat soil, such as rhododendrons, azaleas or hydrangeas, benefit particularly from fertilizing with coffee.

Fertilize Buchs properly with coffee grounds

If you don't want to do without the cheap fertilizer from the filter bag for your Buchs, then mix it with rock flour. This also contains valuable trace elements and minerals and stimulates shoot growth. It also neutralizes the acidifying effect of the coffee, so the soil remains alkaline and the box continues to feel comfortable in it. Both agents mixed together make a wonderful fertilizer. You should use this as follows:

  • Mix the dried coffee grounds and rock powder (14.13€) in a ratio of 1:1.
  • Apply the mixture to the root area around the box.
  • Work them carefully into the soil.
  • Be sure to water after fertilizing to get the nutrients to the roots.
  • Alternatively, you can also stir the powder directly into the irrigation water.
  • Fertilize the book with coffee grounds no more than once a week.

tips

Coffee grounds also have the pleasant side effect that plants fertilized with it are less likely to be attacked by pests. This also applies to the box tree moth - albeit with restrictions. In the event of a heavy infestation, however, only the powerful artillery can help.
