The recommended rates of nutrients and fertilizers needed
to grow healthy almond trees in California, US
The fruit growth has two stages:
- Very intensive growth that follows the flower fertilization (Starts 15-20 days after the peak of the flowering and continues eight more weeks).
- 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.
