It is very important to add the first fertilizers to the soil when the vegetable crop is just beginning to form, for this reason it is worth adding fertilizer to the soil at the stage of formation of the plant itself, additives are also necessary at the time of flowering of the plant, and during active fruiting during growing cucumbers in a greenhouse Don't forget about additional feeding, because the quality and quantity of the harvest will depend on it.
It's also worth considering high-quality soil fertilization if the soil was fertilized only sparingly before planting, or if no beneficial additives were added at all. While store-bought mineral supplements can be beneficial, they're quite expensive. Folk remedies, however, can significantly improve the soil while saving money.
High-quality yeast supplement
Many have probably heard of a folk remedy for feeding cucumbers in a greenhouse, such as yeast. This product can be beneficial for many vegetable crops, as they contain increased levels of beneficial minerals and protein, an excellent building material. Even indoor plants are often fed with these types of additives. To make this fertilizer, you need any type of yeast—both briquettes and loose ones are suitable. The fertilizer is applied exclusively to the roots of the plant. This is done when transplanting the seedlings into the ground and also when the crop begins to actively form new fruit. No more than three applications are sufficient for excellent results. To prepare the solution, take a bucket of water and add just one packet of yeast. Let the fertilizer sit for about five hours, then water.
Fertilizing cucumbers in a greenhouse with folk remedies using freshly mown grass with the addition of yeast is no less effective. Chicken manure is also a popular additive. While not everyone has chicken manure, every gardener has potato tops or weeds in their garden beds.
To make an effective infusion, fill a bucket with water, add one packet of yeast, and add some freshly cut or picked grass (any kind). Let this solution steep for several hours, then use it to water small plants in the greenhouse.
Creating high-quality complementary food from bread
When you don't have regular yeast at home, it's just as effective to use bread instead. And since every bread is made with added yeast, the additional feeding will be just as effective as the first one. The advantage of this top dressing is its purity, since many are against the use of chemicals when growing their vegetables.
To fertilize cucumbers in a greenhouse using folk remedies, fill a bucket with water and add some dried bread. The bucket should be one-third full, or a little more is fine. This fertilizer should be left to steep for several days, allowing the infusion to ferment slightly. Afterward, strain the solution and water the plants in the greenhouse. It's important to remember that the fertilizer shouldn't be used in its pure form, as this can burn the roots and leaves of the plant. For watering, add a couple of liters of the prepared mixture to a bucket of water.
Ash-based fertilizers
All fertilizers containing ash are extremely beneficial for plants. Ash is used not only as a fertilizer for vegetable crops but also for fruit and berry plants, and is also used in irrigation solutions for strawberries and berry bushes. This fertilizer is applied not only at the very beginning of plant development but also injected into cucumbers before fruiting begins. To prepare this mixture, take one full glass of ash, add it to a bucket of water, let it steep for at least a couple of hours, and then water the plants with the resulting solution. This fertilizer is beneficial for all cucumbers, regardless of variety, and is applied four to six times throughout the season.
Foliar feeding for cucumbers
Many people are accustomed to using this type of fertilizer for plants that have already developed fairly abundant foliage. They spray the foliage with special solutions, which can significantly improve fruiting and flowering. This fertilizer can be used as a standalone fertilizer, or as a combined fertilizer along with watering the vegetables with root fertilizer. If the roots of plants are weak, they may not tolerate both feeding and watering, but simply spraying them with the solution provides excellent nutrition without harming them.
How to make fertilizer using iodine
If you need to fertilize cucumbers in a greenhouse using folk remedies (video), iodine is a must. It's worth noting that this solution is an excellent protector against various diseases, which is considered a major advantage when growing cucumbers in a greenhouse.

The described fertilizers help quickly restore the growth of vegetable crops, make them more resistant to various diseases, and help increase fruiting.
