Olive health benefits and therapeutic value

Olives are famous for their health benefits.

  • It can thrive in the poorest of soils, but does best in deep, well drained soil that is rather chalky.
  • Olive trees only bear fruit reliably after ten to fifteen years. If you can, buy them older already!
