Nutrients rates ideal for growing almonds in California, USA

The recommended rates of nutrients and fertilizers needed

Growing almonds in California

 

The fruit growth has two stages:

  1. Very intensive growth that follows the flower fertilization (Starts 15-20 days after the peak of the flowering and continues eight more weeks).
     
  2. Stoppage of the outer part growing and intensive development of the seed.

 

 

 

Fruits can drop due to the following reasons: 

  • Insufficient chilling – disordered awakening and degenerate flowers.
  • Frost damages.
  • Bad weather which interrupts insect and bee pollination.
