Pineapple Propagation Party!

Today the tropical crop propagation continued. Rotem bought five Ananas comosus fruits, known commonly as pineapple. The fruits still have the top shoots attached, this is essential for propagation. Pineapples imported to Israel have the top shoots removed, this is to prevent propagation of foreign fruits, reducing chances of disease introduction.
The best thing about A. comosus propagation is that only the stem, not the fruit can be propagated. Fruit disposal is something we elected to use our stomachs for, which quickly promoted this to my favourite propagation task!


The interesting thing about the fruits we got is the shoot number. I have only ever seen pineapples with a single shoot on top, some of ours have up to seven. This is great for us as it means our five fruits have enough stems to produce 20 plants.


To propagate A. comosus a thin slice is removed from the top of the fruit which includes the stem. The fruit pulp is then pulled away and lower stem leaves are removed. We elected to try two different rooting mediums. Some crowns were split to single which where partially submerged in water, other crowns were left intact and potted in 2:1 perlite:vermiculite. It will be interesting to see if one method is superior.

  1. This was fun to read! Living in Hawaii, we have the Dole Pineapple Plantation. There are fields and fields of pineapples. I have 2 pineapple plants in my yard. One of them produced. The other hasn’t yet. I have heard they only produce once??? I like the details in how you are getting the shoots to root. I’ve wanted to try this and didn’t know if I just stuck it in the dirt, or what? Thanks for sharing! Good luck!

    1. Thanks. Stems only fruit once but after fruiting the plant should produce fresh stems. These are known as suckers and typically emerge from the base of the plant, these will fruit in the following years.

      Rooting stems in a glass jar with water is apparently the easiest way. Pot them on after roots elongate past two inches.
