Growing a good harvest of carrots is not easy. This vegetable has to grow not only greens, but also the fruit itself. Therefore, during the period of active growth of carrots, nutrients and fertilizers are especially needed.

Some of the most effective fertilizers are potassium permanganate and boric acid. Let's talk about the correct use of these preparations for carrots and the secrets of using this type of fertilizer.

Can I water carrots with these products?

Carrots are a very capricious fruit that especially needs fertilization. and reacts very sharply to lack of nutrients.

Therefore, potassium permanganate and boric acid are indispensable helpers in the process of growing the fruit.

  • Boron is a regulator of protein and carbohydrate metabolism, therefore it is necessary for the appearance of the plant.
  • Permanganic Acid (as Potassium Permanganate) protects the fruit from diseases during cultivation.

These substances prevent disease and rot. Therefore, fertilizing with potassium permanganate and boron is not only possible, but also necessary for the healthy growth of the plant.

What is it for?

Potassium permanganate is beneficial for the plant as it:

  • protects against carrot flies, which are the most dangerous pests that affect green and the root crop itself;
  • prevents rotting of the fetus, as it acts as an antiseptic;
  • heals against fungal diseases, root rot;
  • removes stains or damage to the leaves.

The use of a boron solution is necessary because:

  • it increases the size of the fetus;
  • prolongs the storage time of the root crop;
  • improves color, making it more saturated;
  • increases the sugar content, from which the plant becomes sweet;
  • increases yield by an average of 15-20%.

Pros and cons of such feeding


  • improve the taste and appearance of the fruit;
  • protect against diseases and pests;
  • accelerate plant growth;
  • increase the amount of harvest.

Boron and potassium permanganate can be hazardous and harmful to carrots if used improperly. Consider the cons of using fertilizer when overused.

Cons of boric solution:

  • may cause burns to foliage;
  • entails an unhealthy change in the shape of the greenery;
  • causes chronic soil diseases.

Cons of potassium permanganate:

  • may cause plant burns;
  • if used improperly, dries the root, leaves and earth;
  • affects the decline in yield;
  • calls out an excess of potassium.

Step-by-step instructions: how to feed in the open field?


Before starting fertilization, you need to prepare. You will need:

  • watering can;
  • gloves;
  • warm water;
  • manganic and boric acids.

Boron solution preparation

Boron solution can be used without potassium permanganate. He will need hot water with a temperature of up to fifty degrees. Boron is very poorly soluble in cold water, so do not use water below 50-60 degrees.

  1. So dilute one teaspoon of boric acid in 1 liter of hot water.
  2. After the boron is completely dissolved, add 10 liters of warm water at room temperature (20-25 degrees).

We offer you to watch a video about fertilizer for carrots from boron and its preparation:

Preparing a solution from both means

In 10 liters of hot water (50-60 degrees) dissolve 3-4 grams of potassium permanganate and the same amount of boron (about the tip of a teaspoon).

When to use fertilizer?

Fertilize carrots with boron solution in the summer from mid-July to mid-August... Then the fruits will be rich in color and sweet in taste. Fertilizer is best used during the day.

Boron and potassium permanganate are used in early spring when the fruit is growing. Fertilize in the evening.


Before planting, Boron fertilizes not only the growing fruit, but also the seeds... The best fertilizer is boric acid and nitrogen solution. With a lack of nitrogen, the plant stops growing, and the leaves turn yellow and thin.

For healthy growth of carrots, soak the seeds in 1 liter of water, adding a third teaspoon of boric acid and half a teaspoon of nitrogen.

After germination

During growth, carrots really need potassium.... Potash fertilizers protect the plant from fungal and viral diseases. Therefore, during the germination period, the carrots should be fertilized with a potassium solution. It is used 2-3 times: half a teaspoon of potassium in a bucket of water.

An excellent fertilizer is nitrophoska - a complex of nitrogen, phosphorus and potassium. During the germination period, feeding is very useful for carrots. The solution is prepared as follows: one tablespoon of nitrophoska per three liters of water.


Fertilization of carrots should be started when the seeds begin to germinate. During this period, minerals are especially useful, which strengthen the plant. It is best to use potassium, phosphorus and nitrogen. In total, the amount of fertilizer should be about 150 grams, approximately the same amount of all components.

For carrots to grow well 3 weeks after the first fertilization, use a potassium solution with nitrogen: Dissolve one tablespoon of potassium and nitrogen in 10 liters of water. With intensive fruit formation, fertilizer should be used again. Apply fertilizers without nitrogen components. Potassium works best.

Pest control of carrots

To fertilize carrots from pests, you will need a spray bottle, warm water, and gloves.

  • From fungal diseases potassium permanganate helps well: dilute one gram of potassium permanganate in 10 liters of warm water.
  • With powdery ash Dissolve half a teaspoon of the substance in 1 liter of warm water. When carrots rot, a solution of three tablespoons of potassium permanganate per liter of water will be a good medicine.

Spraying with boric acid is very effective in pest control. The solution will also be useful for prevention.

Consequences of improper spraying

Spraying with a boron solution, if the rules are not followed, can harm the fetus:

  • If you exceed the dosage of boron, then the substance will destroy the cellular structures of the fruit, negatively affecting the plant.
  • If the substance is sprayed unevenly, then the hard-to-reach parts of the carrot do not receive the necessary elements for development and health. This reduces the spray effect.
  • If you use cold water, boric acid crystals will not dissolve in water and cause burns.

In order for boric acid to be of one benefit, it is necessary to follow the rules for the manufacture and spraying of the solution. It is recommended to spray only in the evening, or in cloudy weather. Do not allow large drops of solution to form on the leaves.

It is important that young plants are watered over the entire surface area, and grown-ups - only in increments and young leaves.

Proper care of the carrot crop is the key to a tasty and healthy fruit... If you fertilize the plant incorrectly or not fertilize it at all, then you can easily ruin it. Treating diseases is much more difficult than preventing them from occurring. Therefore, carrots require careful maintenance and constant fertilization.
