Avocados will not ripen on the tree. They must be picked from the tree to initiate ripening. The leaves supply a substance that prevents ripening. The best way to store avocados is to leave them on the tree; they will store for 7 months or more when left on the tree.

• Storage below 40 degrees F or above 70 degrees F will cause rot.

• Some varieties will spoil below 50 degrees.

• Ripen at room temperature (60 - 70 degrees F), then store at 45 degrees F.

Avoid: Avocados with dark sunken spots in irregular patches or cracked or broken surfaces. These are signs of decay.

An extra tip: When preparing avocados, to avoid the browning of avocado flesh when exposed to air, immediately place the peeled fruit in lemon juice until ready for use.
