It is possible to protect the garden from harmful insects, as well as fungal and bacterial diseases without the use of special chemicals. It is enough to take herbs that are always at hand: they are cheap, affordable and environmentally friendly. Herbal infusions not only destroy pests, but also have a preventive effect.
It is a mild product that not only effectively fights pests, but also acts as a nitrogen-carbon fertilizer. The high percentage of iron in nettle leaves has a positive effect on plant growth and development.
Nettle infusion is an excellent remedy for fighting late blight. It is best to use it during the autumn processing of the garden before the cold weather, but at other times it is no less effective.
For cooking, you will need to take 1 kilogram of fresh nettle leaves and 10 liters of clean water. The water should be cold.
The leaves will need to be thoroughly chopped, filled with water and insisted for about 12 hours. Then strain and use for spraying.
For a more effective fight against neglected late blight, you can prepare a decoction: for it they take half as much water as in the previous recipe, and bring fresh leaves to a boil. The product is ready for use immediately after cooling.
Due to the content of silicic acid, horsetail is considered one of the most effective means for strengthening plant tissues; it helps horticultural crops grow faster and increases their resistance to changing environmental conditions.
When using horsetail, you don't even need to use phosphorus mineral fertilizers: this amazing plant allows you to absorb phosphorus from the soil much more actively. Horsetail infusion fights well against pests and fungal diseases, and also helps against various types of rust.
The proportions for the preparation of the infusion: 10 liters of water per 1 kg of chopped horsetail. Green shoots must be chopped, filled with water, allowed to brew for 10-12 hours and brought to a boil. After cooling down, strain well and leave for a few more hours.
Before using the product for spraying and watering, it must be diluted with water in a ratio of 1 to 5.
Those who decide to abandon the use of toxic chemicals at their summer cottage are advised to pay attention to fern leaves. They are well suited for killing aphids, snails and slugs. Fern infusions are best used for fruit trees. You will need a garden bracken fern, which is most common in home gardens.
For a 10-liter bucket of water, take a kilogram of chopped fresh fern leaves. They are left to roam for several days. As soon as the fermentation processes come to an end (you will notice the cessation of foam production and a slight darkening of the liquid), the product is ready to use. In its pure form, the infusion is not used, it will definitely need to be diluted in a ratio of 1 to 10. The crowns and trunks of aphids are sprayed with fern leaves, and root watering is also carried out.

Onion peelings contain the following beneficial substances:
1. Rutin and quracetin increase the amount of carbohydrates in fruits, thereby making fruits and vegetables sweet and tasty. Peppers, tomatoes and cucumbers acquire a unique taste and are saturated with vitamins. The large amount of dry matter in the fruit makes it less watery.

3. Phytoncides suppress the number of pathogenic microflora. The husk has a specific smell that many dangerous pests, such as spider mites and aphids, cannot tolerate.
When in contact with phosphoric acid, metabolism accelerates, thereby the root system gets stronger and grows faster. It is saturated with useful microelements, becomes resistant to parasites, which leads to an increase in the number of fruits.
4. Vitamins PP or nicotinic acid accelerates the maturation of the root system, even on difficult soils. Together with vitamin B1, it helps cultivated plants to better absorb nitrogen and phosphorus from the soil, thereby accelerating the production of chlorophyll in the leaves.
5. Vitamin C or ascorbic acid increases the growth rate, making plants less susceptible to lower temperatures.
Before moving on to describing the recipes, let's look at what they use. The main ingredients of nutritional teas are herbs, bacteria and nutrition.

In addition to the grass itself, food for developing bacteria can serve as manure, chicken droppings and sugar in any form. Fermented jam is best suited for these purposes.
When it comes to how to cook bacteria, there are several ways to go or put them together. Let's talk about a few examples of how to get bacterial preparations with your own hands.
