You can leave grapes without fertilizing only during the first year of the plant’s life.
If you continue to ignore this procedure, then, according to the expert of the online publication BelNovosti, scientist-agronomist, landscape designer Anastasia Kovrizhnykh, you will soon notice that the berries and bunches will gradually decrease in size, and the growth of shoots will slow down.
Therefore, experienced winegrowers recommend fertilizing the bushes 6 times during the season.
During bud break
It is enough to scatter ammonium nitrate on the ground - 15-20 g per linear meter between rows. Immediately after this, the fertilizer must be covered with a rake.
Early to mid-May (before flowering)
During this period, grapes require repeated fertilization using ammonium nitrate. This time, 20-40 g of fertilizer should be used for each linear meter between rows.
During flowering
When the grapes are in bloom, the bushes should be sprayed with preparations such as "Bud", "Ovary", etc.
Immediately after flowering
After the flowering period is over, it is necessary to feed the grape bushes with a solution of nitrophoska, which is prepared from 1 matchbox and 10 liters of water.
This procedure has a significant impact on the yield, size and number of berries in the bunch, so it is essential to carry it out.
After fertilizing, it is important to completely exclude nitrogen fertilizers to prevent active growth of green mass to the detriment of fruiting.
In July, before the early varieties ripen
For this top dressing, a solution is prepared from 30-40 g of superphosphate and 10-20 g of potassium sulfate (it is permissible to use diammophoska instead - 40-60 g) per 10 liters of water.
Mid September – October
When digging between the rows, add ash (1-1.5 kg per "square") and manure (8-10 kg per "square"). Ash can be replaced with superphosphate 0, in which case you will need 35-40 g of fertilizer.
