Iodine as a fertilizer for tomatoes


Everyone who grows tomatoes on their plot knows the benefits of dressing. Strong vegetables can resist diseases, invasions of parasites. In order not to use a lot of chemicals, they are replaced with softer natural ingredients. Experienced gardeners find folk recipes very useful in caring for tomatoes. One of these proven methods - feeding tomato iodine. He, like any element, is very useful. But the dose of its use must still be sustained. Otherwise, excessive feeding tomato iodine will lead to an overdose. It is important to remember that in small doses iodine is harmless to humans and plants. Its effect on plants has a lot of positive aspects.

Usually garden crops enough of the amount of the element that is contained in the soil. Therefore, it is impossible to find special preparations with its content. Why then do gardeners actively use iodine to nourish tomatoes? This culture needs additional nutrition and is very responsive to supplementation. Iodine solutions improve the growth of seedlings and help save planting from a formidable enemy - phytophtoras.

Usually iodine is used for tomatoes, as a fertilizer. It is noticed that its beneficial effect on plants is very extensive:

  • improves nitrogen metabolism in plants;
  • seedlings, watered with a solution, grow stronger and healthier;
  • a large number of ovaries are formed;
  • adult plants produce larger and tastier fruits;
  • reduced risk of disease mosaic and root rot;
  • the crop ripens ahead of time.

To feed the tomatoes with medicine must be properly. The need for plants in this element is very small. You need to know the signs of how iodine deficiency occurs in tomatoes. And if these are not noticed, then the feeding must be strictly metered and between them observe the time interval. It turns out that it can replace nitrogen components. Gardeners successfully replace saltpeter with iodine solutions. To feed the tomatoes with a solution of the drug can be on schedule, but sometimes plants need such an additive. When is it necessary to feed tomatoes with iodine? How can a gardener determine that a plant is deficient in an element?

The main symptom will be external manifestations:

  1. Reduced yield. For example, you planted a proven variety of tomatoes in its usual conditions. When you notice a decrease in the number of ovaries or the size of the fruit, then iodine dressing is necessary for tomatoes.
  2. The delay in the onset of the fruiting phase in an adult plant. If during this period they are not fed, the harvest will be low and the fruits - small.
  3. Weak immunity of tomato seedlings. If seedlings grow poorly, get sick, are affected by diseases - iodine is needed.
  4. When tomatoes are affected by mosaic, root rot, brown spot or late blight, spraying with iodine solution is used.
  5. The appearance of characteristic signs of iodine deficiency in tomatoes - thin stems, pale and sluggish leaves also signal the need for additional feeding.

It is known that tomatoes are able to absorb iodine compounds from the surrounding atmosphere. But how much element is needed for good development of the bush? The most obvious characteristic sign of iodine deficiency in tomatoes is not, so you need to carefully monitor the plants from the first days of life. This will help to notice in time that the time has come to feed the tomatoes with iodine. It is best to conduct pre-sowing tomatoes.

How to feed tomatoes with iodine

There are two ways of effective nutrition of a tomato - root and extra root. The efficiency of feeding increases with the alternation of these methods. Experienced gardeners feed tomatoes in a certain phase of development.

Root top dressing

The root method of introduction is very good when the root system is strong and well supplies nutrients to the plant. Works best for seedlings.

The first feeding with iodine is carried out when a second pair of leaves appears on the seedlings. The leaf area is still very small in order to absorb the beneficial components, so it is best to deposit them through the root system.

Nutrient solution for feeding tomatoes prepared in a ratio of - 1 drop of the drug to 3 liters of warm water.

Pre-watered the soil around the stem, and then moisten the soil with a solution. Even a one-time dressing tomato iodine gives a tangible result. If you shed adult tomatoes during the fruiting period again, they will thank you for a good harvest of large fruits.

The second time fertilize the plants in the phase of setting brushes. In this case, 3 drops of iodine per bucket of pure water will suffice.

Important! Use for dressing tomato warm water.

For tall plants, one liter of solution is needed for each bush, and 0.7 liters is enough for undersized.

It is desirable to hold the third root dressing of the tomato during the fruiting period.

This time, along with iodine, they make top dressing a boric acid tomato. Heat five liters of water to a hot state and dissolve 3 liters of wood ash (sifted) in it. Cover the container and insist ash for one hour. Then dilute to a volume of 10 liters with warm water and add 10 ml of medical iodine and 10 g of pharmaceutical boric acid. Stir and insist day. To fertilize tomatoes, one liter of this infusion is diluted in 10 liters of warm water and watered under the root bushes. Top-dressing of tomatoes with boric acid and iodine will well strengthen the resistance of plants at the moment of fruiting.

Foliar feedings

Foliar method alternate with root dressing tomato. Ten liters of space consume 1.5 liters of the composition. The spray solution is made with milk. Prepare it from 250 ml of milk (non-fat), 5 drops of medical iodine and 1 liter of water.

Spray tomatoes in the morning or in the evening when there is no bright sun. Use a hand sprayer or sprayer with a nozzle that disperses a fine mist.

Important! Strictly follow the dosage of iodine, otherwise you can burn the leaves on the tomatoes.

And do not get carried away too much with top dressing tomato iodine and boric acid. The excess of elements will lead to the deformation of the fruits and brushes of the plant.

A very interesting method of dealing with late blight tomato in the greenhouse. Gardeners hang open jars of iodine throughout the area. This disinfects the room well, however, one cannot stay in the greenhouse for a long time. Iodine is a volatile element, and overdose is dangerous to humans.

A warning! Indoors, use the drug with caution.

Another proven fertilizer for tomatoes is whey. Only you need to take the whey when souring milk, and not from cooking cottage cheese. Serum diluted in water (1:10), sprayed tomatoes very often, which for some gardeners tedious. You can reduce the number of sprays to one per week.


Thus, it should be noted that timely feeding of tomatoes with iodine can significantly improve the yield and taste of fruits, reduce the incidence of plants.
