Feeding tomatoes and cucumbers with yeast

Any garden crops respond positively to feeding. Today there are many mineral fertilizers for tomatoes and cucumbers. Therefore, vegetable growers often face a dilemma of which fertilizers to choose for their crops. Today we will talk about feeding plants with yeast. This method cannot be considered new, it was still used by our great-grandmothers, when they did not know about mineral fertilizers.

Let's take a closer look at what is the use yeast feeding for cucumbers and tomatoes. Experienced gardeners do not need our advice, in their opinion, yeast help to grow a rich harvest of juicy and tasty vegetables. Beginners need to carefully consider the recommendations.

Yeast in the garden

Yeast is a culinary product. But they can be successfully used for feeding cucumbers and tomatoes.

Why are they useful:

  1. First, they contain proteins, trace elements, amino acids, and organic iron. All of them are as necessary as air for cucumbers and tomatoes.
  2. Secondly, it is a safe, environmentally friendly product. Therefore, you can safely give vegetables grown on your site even to small children.
  3. Thirdly, feeding with yeast helps to improve the microflora of the soil, yeast bacteria suppress harmful microorganisms.
  4. Fourth, you can use organic fertilizer at different stages of vegetable development. Plants adapt faster, thrive both outdoors and indoors.

How does yeast work on plants

  1. Cucumbers and tomatoes quickly grow green mass, a powerful root system. And this, in turn, has a positive effect on the yield of cucumbers and tomatoes.
  2. Plants become more stress-resistant even under unfavorable growing conditions (this applies primarily to open ground).
  3. Immunity increases, when planted in the ground, cucumbers and tomatoes take root better.
  4. Diseases and pests bother plants that are fed with yeast less.

Solutions are prepared from dry, granular yeast or raw yeast (also called live). Like any fertilizer, this product requires correct proportions.

Yeast contains beneficial bacteria, which, when they get into warm and moist soil, immediately begin to vigorously multiply. Yeast as fertilizer contains potassium and nitrogen, which enrich the soil. These trace elements are necessary for cucumbers and tomatoes for normal development.

Important! You need to feed the plants after watering the ridges.

How is yeast feeding used?

They knew about feeding garden crops with yeast even in antiquity. Unfortunately, with the advent of mineral fertilizers, this method began to be forgotten. Gardeners with a long experience in growing tomatoes and cucumbers believe that yeast feeding is no worse, and in some cases even more effective than chemical preparations.

In fact, she is superb growth stimulant, a biologically active and harmless supplement, activates the immune system of plants. As for the harm, there is no such information. The only thing gardeners should remember is that yeast acidifies the soil.

Comment! After top dressing, the soil must be dusted with wood ash to neutralize the acid.

For the first time, yeast for feeding is used even at the stage of growing seedlings of cucumbers and tomatoes. Re-fertilize the plants three weeks after planting the seedlings and when the first flowers appear. Root and foliar feeding of tomatoes is carried out after 15 days, cucumbers after 10.


Since yeast has been used to fertilize tomatoes and cucumbers for hundreds of years, there are many recipes that have been proven in practice. In some of them, only yeast is used, in others, wheat, nettle, hops, chicken droppings, and sugar are added to prepare valuable top dressing. There are also recipes based on black bread.

Attention! If you don't trust yeast feeding, test its effect on several plants.

Just yeast

  1. First recipe. A thawed pack of raw yeast (200 grams) must be poured with a liter of warm water. If the water is chlorinated, it is first defended. Neither cucumbers nor tomatoes need chlorine. It is better to use a container larger than one liter, since yeast bacteria will begin to multiply, the liquid will increase in volume. The leaven is infused for at least 3 hours. After that, it is poured into a bucket and topped up to 10 liters with warm water! This solution is enough for 10 plants.
  2. Second recipe. Take 2 7 gram bags of dry yeast and a third of the sugar. Put them in a 10-liter bucket of warm water. Sugar speeds up fermentation. Before watering, dilute in five parts of water. Pour one liter of solution per plant under cucumbers or tomatoes.
  3. Third recipe. Again, take 10 grams of dry yeast, two large tablespoons of granulated sugar. The ingredients are poured into 10 liters of warm water. It takes 3 hours to ferment. It is best to place the container in the sun. The mother liquor is diluted 1: 5 with warm water.
  4. Fourth recipe. To prepare the mother liquor, use 10 grams of yeast, a third of a glass of sugar. All this is poured into a ten-liter container with warm water. To enhance the action of yeast fungi, add 2 more tablets of ascorbic acid and a handful of soil. This dressing for tomatoes and cucumbers must be kept for 24 hours. The leaven is stirred from time to time. The proportion is identical to the second and third recipes.
Attention! The container with the yeast feeding during fermentation must be closed with a lid so that insects do not get into it.

Yeast top dressing with additives

  1. This recipe will require a large container of 50 liters. Green grass is mowed in advance: during fermentation, it gives nitrogen to the solution. Quinoa is not used for feeding tomatoes, because phytophthora spores like to settle on itThe chopped grass is placed in a container, 500 grams of fresh yeast and a loaf of bread are also added here. After that, the mass is poured with warm water and left to ferment for 48 hours. The readiness of feeding can be recognized by the specific smell of fermented grass. The stock solution is diluted 1:10. Pour a liter jar of yeast fertilizer under a cucumber or tomato.
  2. To prepare the next vegetable dressing, you will need one liter of homemade milk (will not work from packs!), 2 bags of granulated yeast, 7 grams each. The mass should ferment for about 3 hours. One liter of mother liquor is added to 10 liters of warm water.
  3. Top dressing works well with chicken droppings... You will need: granulated sugar (a third of a glass), wet yeast (250 grams), wood ash and bird droppings, 2 cups each. Fermentation takes a couple of hours. To prepare the working solution, the mass is poured into a ten-liter bucket with warm water.
  4. This recipe contains hops. Collect one glass of fresh buds and pour into boiling water. Hops are brewed for about 50 minutes. When the broth has cooled to room temperature, flour (4 large spoons), granulated sugar (2 tablespoons) are added to it. The container is set aside for 24 hours in a warm place. After the time has elapsed, add two grated potatoes and set aside for another 24 hours. Strain the starter culture before preparing the working solution. For watering cucumbers and tomatoes, add another 9 liters of water.
  5. Instead of hops, gardeners use wheat grains. They are first germinated, then ground, flour and granulated sugar, dry or raw yeast are added (see the description of the recipe with hop cones). The resulting mass is boiled in a water bath for a third of an hour. In a day, the mother liquor is ready.Top dressing for tomatoes is the same as in the recipe above.
Comment! You can use yeast dressing only when the soil is warmed up enough. In the cold, bacteria don't work.

Another yeast-based feeding option:

Let's summarize

It is unrealistic to tell about all the recipes for yeast dressings in one article. I would like to believe that a safe way of growing tomatoes and cucumbers will interest novice gardeners. After all, this organic fertilizer nourishes not only the plants themselves, but also improves the structure of the soil.

You can carry out foliar feeding of plants with yeast. This use of organic fertilizer relieves tomatoes from late blight, and cucumbers from spotting. The only drawback of foliar dressing is that the liquid does not adhere well to the foliage. And in general, as noted by long-term gardeners, yeast feeding allows you to get a harvest of environmentally friendly vegetables.
