    How do pineapples grow?

    The pineapple plant grows 24 to 30 inches high with pointed and spiny, hard, green leaves that arise from a tight center.  One fruit grows out of this center on a stalk.

     The fruit itself is 6 to 10 inches tall, ovular with a thick skin and the same spiny leaves growing out of the top - which can be planted to create a whole new pineapple plant.


    USDA Zones 10 and 11. A crop can be planted any time in these two zones. Click here to view USDA Plant Hardiness Zone map.

    A pineapple takes over 4 years of growth from flower to ripened fruit.

    Growing and Processing Pineapples

  • Propagation:

    How are pineapples propagated?


    Crowns ( the top of the pineapple), suckers (or ratoons) and seeds can all be used in propagation.


    Although one plant yields only one pineapple, the suckers growing below the leaves of a mature mother plant can be replanted to create more plants. 


    Seeds are tiny and hidden in the flesh just below the skin. Seedlings are transplanted to the field after a year of growth and bear fruit 3 to 5 years later.

  • Harvest:

    When are pineapples ready for harvest?

    Before it ripens, a pineapple is inedible and poisonous.  It irritates the throat and can act as an extreme purgative.


    Size and color are not reliable indicators of ripeness, it can be difficult to judge when a pineapple is ready for harvest.  Fruits are picked when there is a slight yellowing around the base. A good ripe fruit has a dull, solid sound, a hollow thud can mean the fruit is immature and of poor quality.


    If the leaves on top of a pineapple can be easily pulled, the fruit is ripe.


    Harvested fruits must be protected from moisture to prevent rotting when transported.
