Don't count on a good grape harvest without regular fertilization. The bushes also need to be tied up periodically, and the branches should be pruned.
In the first year of life, the plant needs phosphorus for its roots. Nitrogen is also required, which is responsible for the growth of aboveground growth. Potassium is needed for good fruiting. Basically, dressing is applied in the spring in the holes around the bushes. Also, the procedure can be carried out in the fall, but the composition of the additives will be different.
The first processing of grapes is carried out at the budding phase, the second - after the end of flowering, and the third - after harvest.
Nitrogen, potash and phosphorus fertilizers
Use urea or carbamide to feed adult vines. Ammonium nitrate is used mainly in spring, during flowering and plant growth. It is undesirable to add the substance when the berries are ripening.
Ammonium nitrate is recommended dry. This fertilizer is scattered around the bushes.
Thanks to potassium, plant development is accelerated. It absorbs potassium from the soil, so it needs to be fertilized with potassium annually.
Potassium sulfate is suitable for feeding the leaves. It is diluted in water before use. Superphosphate is also added there to neutralize acidity.
Phosphorus is taken as a top dressing in the spring months. It is great for helping the culture to develop and bloom.
Superphosphate is used for all types of soils. Before adding it to acidic soil, you need to put lime in the solution. It is important to follow the instructions for use exactly.
Complex feeding
For spring feeding, they often take azofoska and bischofite. The latter contains iodine, magnesium, bromine and boron. This is a great tool for sheet processing.
Azofoska can be purchased dry or liquid. The main components here are potassium and phosphorus.
Home remedies
Litter is an excellent fertilizer for grapes. It is used only as a solution of one kilogram of droppings and 20 liters of water. The solution must be infused for seven days. The soil is watered at a short distance from the bushes.
Top dressing can be mineral, based on yeast, herbal infusions and eggshells. You need to take dry yeast, dilute them in warm water, insist the product for about six hours, stirring constantly. For each plant, a liter of composition is used.
In spring, wood ash can be added, which is especially useful on acidic soil. Ashes from the burning of raw materials are not brought in, this negatively affects the plant.
Ash contains phosphorus, boron, potassium, magnesium. They are necessary for the grapes for flowering and ovaries. Ash is used dry, it is sprinkled with soil when planting a plant.
