How to use iodine for cucumbers in a greenhouse and why do it
I always add a couple of drops of iodine to water for watering indoor flowers. And you can use iodine for cucumbers in a greenhouse and how to use it correctly – spray or water? My bushes are already starting to form an ovary, wouldn’t it be too late to feed them this way? I try not to resort to chemistry and give preference to folk remedies.
Today, if you wish, you can purchase a wide range of various preparations for fertilizing cucumbers and other garden and greenhouse crops. But do not discount the good old methods, time-tested and long-term practice of summer residents. For example, using regular iodine for cucumbers in a greenhouse will provide plants with this vital trace mineral, which will have a positive effect on crop yields. In addition, unlike special fertilizers, iodine is several times cheaper, so that especially on the budget, such feeding will not “hit”.
What does “iodine” feeding of cucumbers give?
The microclimate of the greenhouse allows you to get an early harvest, because in warmth and with high humidity, cucumbers develop faster. However, limited space requires more attention. First, plants need adequate nutrition, which they receive through regular feeding. And secondly, greenhouse humid air is “to the liking” not only of cucumbers, but also of various fungi, which is fraught with a disease of the culture.
With the help of ordinary iodine, which is in the first-aid kit in every home, you can not only prevent the deficiency of the microelement of the same name, but also protect cucumbers from diseases. An antiseptic will serve as a fertilizer, and a fungicide, and even an insecticide. It can be used both for the prevention and for the treatment of certain diseases of the culture..
Using iodine to process cucumber beds, not only in the greenhouse, but also in the open field, you will only get a positive resultat, namely:
- accelerate the growth of bushes;
- feed the bushes with minerals;
- restore the tone of wilted leaves;
- stimulate fruit setting;
- enhance the development of the root system;
- lengthen the fruiting period;
- increase the resistance of plants to adverse conditions;
- protect cucumbers from powdery mildew, late blight, root rot, peronosporosis;
- prevent the appearance of insect pests.
Iodine for cucumbers in the greenhouse – how and when to use correctly
The advantage of using iodine is not only in its availability, but also in the fact that this agent can be used at all stages of the vegetative development of the culture. Pre-sowing seed treatment already at the initial stage of cultivation will protect the seedlings from fungal infections. And iodine feeding of seedlings and adult plants will improve their development and fruiting.
In order not to harm the cucumbers, it is necessary to remember about two disadvantages of using iodine in the greenhouse. First of all, the vapors contain toxic fumes, so it is imperative to ventilate the greenhouse after the “iodine procedures”. In addition, it is important to accurately observe the dosage, otherwise the plants will receive a chemical burn..
Top dressing recipes
As for the specific methods and consumption rates, it all depends on the timing and purpose of using the antiseptic:
- Seed dressing before sowing. The planting material is soaked for 6 hours in a solution of iodine with water (1:10). Then the seeds are washed with clean water and dried..
- Top dressing of cucumber seedlings. As soon as the senses have 3 true leaves, you can start spraying them. For these purposes, it is better to dilute iodine in milk with water, and for better adhesion, add a little soap. First, dissolve 20 g of soap shavings in 1 liter of warm milk, then pour this mixture into a bucket of water and at the end add 30 drops of iodine. With this tool, you can spray cucumbers every 10 days throughout the season..
- Disease prevention. The maximum effect can be obtained using a combination of two antiseptics – iodine and brilliant green. They need to be dissolved in equal amounts (20 drops each) in 10 liters of water and water the plants under the root every 10 days. It is important not to allow the solution to get on the aboveground part of the bushes..
- Pest control (May beetle larvae). Dissolve 20 drops of iodine in a bucket of water and spill the soil under the bush every 5 days.
