With milk

Popular with superficial feeding of tomatoes recipe. Milk contains a lot of elements capable of bringing the plant to benefit: magnesium, potassium, phosphorus, etc. D., And besides, improving the growth of amino acid tomatoes.

It can be added to iodine and manganese, in the ratio of the field of crystals per 100 ml of composition. Manganese – Another antiseptic, well-working on plants and at the same time containing potassium and manganese, positively affecting their growth. As in the case of iodine, when working with manganese, it is important to comply with the proportions so as not to burn the plant.

On raw yeast: 10 liters of heated water, 100 grams of yeast, 2 tablespoons of sugar. The composition must pose before the appearance of bubbles. Sugar in these mixtures – optional ingredient, enhancing fermentation.

It is believed that it is worth using it if it is planned to make fertilizer by irrigating the root, and with normal feeding you can do without adding it.

Yeast – Powerful natural stimulant, generous for vegetable substances. This product strengthens the roots and stems of tomatoes, accelerates growth and stimulates flowering. Do not forget – excessive yeast feeding can harm, and not benefit! A significant amount of nitrogen-separated nitrogen leads to thickening of leaves and a drop in yield. For the period of growth, such an additive is optimally used 4 times, combining it with rich potassium and calcium fertilizers, since these substances absorbs nitrogen.

Methods and rules of application

Sobering with what to feed, let’s go to how it needs to be done. Separate root and surface feeding with iodine. To achieve the maximum result, they should be alternate. The root technique is better suited for seedlings – it allows you to increase the future yield of tomatoes up to 15%. The first time is processed after the second pair of leaves. The second processing is recommended at the stage of the emergence of the wound, the third – in the period of fruiting. But there is an opinion that for the period of aging fruit feeding with iodine better and stop at all, so this is a controversial moment.

However, iodine even treated seeds for their pre-disinfection. The solution for them is prepared in the ratio of a drop (0.1 g) iodine per liter of water. The fertilizer is wetted a piece of gauze, into which the seeds wrap up and leave them for 7 hours. Wash seeds after the procedure is not necessary, you should only remove them in a dark place.

You can do tougher, heating a solution to fifty degrees, but then only the strongest of seeds will survive.


Before starting a conversation about watering tomatoes with compositions with iodine, let’s say a few words about their irrigation, since if it is incorrect, then no feeding will help. The soil for tomatoes should have a humidity above 80%, but also to fill the plant – you risk changing the roots. Avoid watering on the Sun – focused rays can leave burns on the leaves.

Seedling loves water of approximately 20-degree temperatures, exchange processes are accelerated when watering. Exercise the procedure is best twice a day. After 15 days, you can go to one-time watering. When tomatoes went into color, you can cut the frequency of irrigation to the pair-triple once a week, after flowering, the tomatoes are not so demanding to watering.

Since the establishment of marching, watering is produced under the root, before the formation of a small puddle. And when fruits begin to form, watered every day or every other day, increasing the water consumption on the bush to two liters. Performing watering fertilizer, it is worth remembering about several ordinary rules. First, it is impossible to use cold water for this – this can cause the root system of the “shock” tomatoes. Secondly, water is better to have a slightly wet soil. Thirdly, you need to do it clearly under the root. The day before moving the seedlings to the beds, they need to be treated with fertilizer, abundantly irrigated with a solution of iodine, prepared in a proportion of 3 drops by 10 liters of water – it will kill the habitable infection and will help tomatoes get better.

Spraying – the most popular method of extractive plant treatment. For the first time it is produced somewhere two weeks after landing in a greenhouse. Spray the beds need evenly, holding a sprayer at a distance from the bushes.

Spraying season in the greenhouse ends in August, and plants in the open soil can be calmly sprinkle at the end of September. Cool weather from the procedure is better to refuse. Minimum temperature – +18 degrees.

There is a couple of cunning tricks suitable, though only for greenhouses that can replace spraying. They will save your time, but in efficiency will still be weaker. Trick is the first: to hang for every two square meters of greenhouses on an open iodine bottle. Do not forget only that it will be impossible for a long time in such a room. Second trick: Use Space Tea Package, Ioda Capper. They hang in a greenhouse according to a scheme similar to bubbles.

Another trick: if you add a bit of economic soap into solution, then it will not give it to drain, and therefore effectiveness will increase, and the flow is “.

Precautionary measures

Everything is good in moderation. So iodine helped your crop, and did not burn the plants, observe simple precautions.

  • The first watering of the iodine should not be carried out earlier than a week after the first feeding. Water not root, and earth!
  • If brown spots began to appear on the leaves and fruits – you have moved. Only frequent and abundant irrigated.
  • When using iodine in the greenhouse, it must be regularly ventilated.
  • Do not do too sturdy solution, t. To. This is a potent substance, in the specified doses of it more than enough. When the concentration is exceeded, the harm can also get a bush, and you, if you breathe a pair.
  • Yes, iodine is harmless in small doses, but even 3 grams of substances that have fallen into the body can lead to a fatal outcome. Clearly observe the recipe for an increase in the yield, so as not to burn the plant, store the solution in an inaccessible place for children.

Some fear of the risk of accumulating iodine in the fruits. This fear is clear, but when compliance with dosages, the concentration of iodine in tomatoes will (if it will be at all – there is an opinion that iodine does not accumulate in them) meager. In the end, we apply iodized salt.
