The fertilization must be directed primarily to obtain a uniform and synchronized flowering. In this context, nitrogen should not be used excessively and stress situations caused by, for example, thermal fluctuations (cold return) and water imbalances should be avoided.
Phosphate fertilization in vegetative recovery is essential to renew the root system and consequently improve water and nutrient absorption.
It is very important to protect the plant from any cold returns that can cause serious damage to production.
THE TECHNICAL LINE
Fertilization at vegetative growth:
UNIVERSAL UP or RED BALL at a dose of 200-300 kg/ha - Granular to the ground
HYDROSTAR - 10 kg/ha + SUPREMO - 20 litres/ha - in fertigation, from vegetation to pre-flowering
In case of forecast low temperatures and cold weather:
Foliage: CERERE at a dose of 1-1.5 liters/ha 24-48 hours before the start of the heat fall (also usable in case of full flowering).

n.b.: technical background:
For the drupacee to check if they have received enough cold hours, you must:
- Determine the "cold" period (e.g. October-January)
- Count the number of hours in this period between 2.5 and 9.1 °C.
- Consider the following requirements:
- apricot 400-600
- peach 700-800
- Apple 800-1000
- almond 250-500
- cherry 700-800
