Bushes need rationing of the load.
Watering

The cultivation of many bushes involves the use of a trench irrigation method or drip irrigation. Watering of the grapes stops at the time of flowering and 18-20 days before the start of the harvest. Moistened soil is mulched to retain moisture and prevent early germination of weeds.
Top dressing
Plants need fertilizer three times per season:
phosphates and compounds with potassium in the spring;
nitrogenous fertilizers before the start of the growing season;
superphosphate or ammonium sulfate in the autumn season, before wintering.
And also wood ash is used as fertilizer, which nourishes the root system and prevents the development of infections.
