Radish - one of the earliest ripening types of vegetables, is a type of Radish of the family red-colored, the characteristic pungent taste is a sign of the presence of mustard oil in the root vegetable. Radish allows you to fill the lack of vitamins and minerals in the human body, helps to properly assimilate proteins, strengthens the immune system, normalizes cholesterol levels and is a means of preventing diabetes mellitus.

This vegetable crop is rich in vitamins B, C and E, as well as potassium, phosphorus, sodium, iron, etc. With proper sowing and feeding, the crop can be harvested both in early spring and throughout the summer.

The need for timely feeding

Radish is a rather unpretentious plant, it can grow on neutral, slightly acidic and alkaline soils, reacting negatively only to acidic soil. However, timely and competent feeding is necessary for the plant - it makes it possible to nourish with the necessary trace elements necessary for the correct and rapid growth of the root crop.

Important! Do not overdo it with fertilizers, because with a high content of certain substances in the soil, radishes can "go to the tops" or give an arrow ahead of time, which will negatively affect the growth of the root crop.

Differences when growing outdoors, in a greenhouse and at home

Radishes can be grown outdoors, in a greenhouse, at home on a windowsill, or on a closed balcony. In this case, the proportions of feeding the plant remain the same. However, certain rules for growing a plant:

  1. Optimum temperature: + 17 ° + 20 ° C. At a higher temperature, the leaves of the plant will stretch to the detriment of the fruit or the plant will go into seeds.
  2. Watering: often and in small portions.
  3. Lighting: 8-10 hours of daylight hours. In early spring, it is better to choose a sunny place for sowing, in the middle of summer - partial shade.
  4. Depth of the involved soil: 15-20 cm.
  5. Distance between seeds: 4-6 cm.
  6. It is good if previously grown on the soil: tomatoes, cucumbers, potatoes, as well as plants of the legume family.
  7. It is advisable to soak the seeds for 12 hours in advance (read more about seed treatment before planting here).
  8. Radish DOES NOT LIKE:
    • Acidic soil.
    • Heavy soil. It is necessary to loosen the soil, this helps to form a root crop of the correct shape and prevents the plants from shooting.
    • Fresh organic fertilizers such as manure. In this case, the radish will be empty.
    • If earlier on the same land grew: cabbage, turnip, radish, daikon

Difference in fertilization time

After germination

If you fertilize the soil correctly before planting, then the young shoots of radish do not need feeding, however, if it was not possible to fertilize the soil in advance, you can feed it with any potash or phosphorus-potassium fertilizer at the stage of the appearance of the first 2-3 leaves according to the instructions on the package.

When the plant has already grown

When the plant has grown, its condition can be used to determine what kind of fertilizer it needs at a given moment. You should pay attention to the following signs:

  • If the leaves have grown too large, and the root crop has stopped growing, a phosphorus-potassium dressing should be applied. In addition, you can water the radish with a special solution consisting of 1 glass of ash, 20 g of potassium sulfate, 40 g of superphosphate per 10 liters. warm water.
  • If the leaves of the radish are pale, then it lacks nitrogen. Fertilizer GROWTH or 1 tsp. urea dissolved in 10 liters. water will provide growth not only for the leaves, but also for the roots themselves.
  • If the plant is affected by a bear or cruciferous fleas, it should be 10 liters. stir water 500 g of ash and 60 g of crushed or grated laundry soap. Spray the plant with the resulting solution. In addition, you can dilute mustard powder in water and sprinkle the plant with it.

The use of various means depending on the season

Soil preparation

It is best to prepare the soil for sowing radishes in autumn or early spring.when the snow melted. How to fertilize the soil in spring when planting seeds for their quick growth and better harvest? To do this, you need to dig up a piece of land on which seeds will be planted and apply the following fertilizers per 1 m² of the area:

  • 1 tbsp. sifted ash;
  • 10 g of urea;
  • 40 g superphosphate.

Another composition of spring fertilizers for radish is also possible:

  • 20 g of potassium sulphide;
  • 4 kg. humus;
  • 20 g superphosphate;
  • 10 g of saltpeter.

How to treat the area before seed sprouting?

Before seed germination and at the initial stage of growth, complex mineral fertilizers and growth stimulants can be used, such as the:

  • agrovita;
  • gumi-omi;
  • kalimag;
  • agriculture;
  • potassium monophosphate;
  • potassium sulfate;
  • potassium humate;
  • phosphorus-potassium, etc.

During the growing season

During active growth, you can feed the radish with the following fertilizers:

  • ammonium nitrate;
  • superphosphate;
  • potassium sulfate.

Application rate - guided by the instructions of the selected product. You can buy them at any garden supply store or online store.

The average cost of fertilizers in Moscow and St. Petersburg is from 30 to 100 rubles.

Compost infusion

One of the easiest ways to make your own radish fertilizer is to infuse it with compost. To do this, you need to dilute 500 g of mature compost in 10 liters. water and let it brew for three days, after which the infusion should be thoroughly filtered and watered without diluting the plants with water. It is highly undesirable to water radishes with this solution under the scorching sun.

On herbs

Same herbal infusions can be used as fertilizers... They are quickly absorbed, safe and can be used at any stage of plant growth. It is advisable to use the following herbs in the infusion:

  • chamomile;
  • comfrey;
  • rape;
  • tansy;
  • nettle;
  • horsetail and others.

In addition, you can add to the broth:

  • wood ash;
  • onion husks;
  • bird droppings;
  • garlic arrows.

From wood ash

Wood ash replenishes potassium deficiencies in the soiltherefore it can be used as an independent fertilizer. Ash is fed to radishes not only before planting, but also during the growth of the vegetable, you can water it with liquid ash top dressing. To do this, stir 250 g of ash in 10 liters. water and in the evening water the plant under the root with this solution. If ash is used as fertilizer, it is advised to adhere to some rules:

  1. Do not add ash to alkaline soil.
  2. Ash completely neutralizes the effect of nitrogen fertilizers, especially ammonium nitrate and urea, so they should not be applied earlier than a month after using the ash.


Fertilization with nettle - heals the plant from red-colored flea beetles, accelerates the formation of chlorophyll and root crops. To do this, cut a bucket of nettles and fill it with water, leaving it in the sun for a week, remembering to stir regularly. Then add the infusion to water 1 to 10 and water the beds in the aisles.

You need to harvest the crop no earlier than three days after the top dressing has been done plants. Otherwise, nitrates will not have time to break down in the root crop and there will be little benefit from eating such vegetables.

Undoubtedly, in order for the radish harvest to please the gardener with its shape and taste, you should invest a little of your strength in it and pay attention and time to feed it. But in this case, the result will not be long in coming, and nature will certainly reward the gardener with a juicy, healthy and ruddy harvest of radish.
