Our grandmothers already knew the benefits of yeast. Not only for baking or for our well-being, but also as fertilizer in the garden at home. You can find out everything about production and use below.
In a nutshell
- Heavy eaters especially love yeast
- Use as fertilizer, spray and compost accelerator
- Can be administered as fertilizer every 14 days
- Yeast only has an indirect effect on plants
- Yeast fertilizer can also be used for indoor plants
Contains important nutrients
Yeast is made from cultured yeast. These are unicellular yeasts. One gram of baker's yeast consists of up to a billion yeast fungi. Baker's yeast or brewer's yeast contains important nutrients such as:
- iron
- Folic acid
- Biotin
- niacin
- zinc
- Vitamins B1, B2 and B6
- magnesium
- Potassium and
- different proteins
When using yeast as a fertilizer in the garden, it does not work directly. In other words, it is not the plants that are directly supplied with the nutrients, but the microorganisms living in the soil. The administration of yeast stimulates them to decompose the constituents of the soil more quickly and to make them available to the plants as food.
Preparation of the fertilizer solution
There are two different ways to make a fertilizer solution from baker's yeast:
Fermented yeast solution
- 100 g baker's yeast
- 200 g of sugar
- 10 l of warm water
Manufacturing:
- Crumble the yeast
- mix with sugar
- slowly pour warm water
- mix well
- let ferment for a week
- Use diluted 1:10 with water
Not fermented yeast solution
- a cube of baker's yeast
- one liter of warm water
Manufacturing:
- Crumble the yeast
- Pour in some lukewarm water
- process everything to an even mass
- Add the rest of the water, stir
- let rest for an hour
- then use possible
Rainwater or potato water should be used with both fertilizer solutions if possible.
Tip: Dry yeast can also be used. This should always be dissolved in hot water before adding cold or lukewarm water.
Heavy eaters love yeast
The fertilizer solution is completely organic, environmentally friendly and odorless. It can also be administered every 14 days to once a month from spring to the end of summer. Heavy consumers in particular benefit from this. The baker's yeast can either be worked into the soil or added to the irrigation water. Below is a brief overview:

frequently asked Questions
No. The fertilizer is fully organic and there is only indirect fertilization. It is not the plants that receive the nutrients immediately, but they serve to nourish the beneficial microorganisms living in the soil. These then break down the ingredients present in the soil and make them available to the plants in the form of broken down nutrients.
It is also possible to work the baker's yeast directly into the soil. This is chopped up and spread evenly on the floor. Either it can be worked in with the rake or it is dug under. The best time for this is autumn. In addition, the baker's yeast can also be added directly to the compost heap. The yeasts accelerate the formation of compost. Irrigation water with yeast that is not used should also end up on the compost.
In addition to being used as a fertilizer, it can also be used as a spray against pests and diseases. This requires 100 g of baker's yeast, 500 ml of milk, 10 l of water and 1 tablespoon of soft soap. The baker's yeast is crumbled in warm milk and then the warm water and soft soap are added. This allows the plants to be carefully hosed down. This mixture provides protection against late blight, tuber rot, gray mold and potato powdery mildew.
