How to grow a pineapple from scratch (from a pineapple)
This year, I’m working hard to transform my little patch of lawn into a productive food forest – or the beginnings of one, anyways. (They say Rome wasn’t built in a day, and I’m pretty sure they say a forest doesn’t grow in a year – but the foundations can be laid, for sure!)
If I was to buy a heap of plants to fill the space, I’d be bankrupt pretty quickly. Where possible, I’m trying to fill the space with plants I’ve grown from nothing – or rather, from cuttings, seeds, roots and runners.
It’s not possible with every plant I’d like to have, but there are lots of options.
I love the idea of using ‘waste’ to create something new. And I love watching nature do its thing. One of my favourite things to grow right now is pineapples. They are magical.
I thought I’d talk you through the how.
Pineapples are a tropical plant, but they will grow successfully and fruit in Perth (where I live). They’re also quite a fun plant, so they look good regardless of whether they fruit or not – but having plants that could potentially also feed me in the future is a winner.
If you’re not in a Mediterranean or tropical climate, you can still grow pineapples, but they’ll need to be kept indoors during the cooler months. I’ve read that it’s possible to get them to fruit, but I imagine it’s a lot more work.
Nevertheless, they make a fun indoor plant if you’re in colder climes. A cool experiment. A good conversation starter. An excellent gift.
Here’s how you grow one.
Step-by-step guide to growing a pineapple
You’ll need a pineapple with its green spiky head attached. If you’re lucky, you’ll find a pineapple with a more than one head, or possibly a main head and side sprouts. For every head, you’ll be able to grow a plant, so the more the merrier.
This pineapple has a main head, and a little side shoot to the side. Two future pineapple plants for the price of one pineapple.
Next, chop off its head – or rather separate the fruity part from the green spiky part. You want to try and cut between the fleshy pineapple part and the head so that there is no fruit attached to the green head part. (The fruit will rot which won’t be good for the plant.)
Pull off some of the bottom outer leaves. You may see roots when you do this, or you may just see little stumps that will grow into roots. Pull off enough that there’s a small ‘stem’.
Sit the pineapple on top of a jar filled with water, ensuring the stumpy root part is submerged. The leaves can help prop the plant up on top of the jar.
Suspending the pineapple rather than sitting in a saucer ensures the roots have space to grow downwards.
The pineapple may sprout roots straightaway, or nothing may happen for ages. (I’ve tried two varieties: one sprouts straightaway and the other takes forever.)
Ensure the water is topped up so the root part stays submerged. I haven’t found it necessary to change the water.
Eventually, roots appear.
I wait until the roots reach the bottom of the jar (we are talking a few weeks at least), and then I repot in some well draining soil. Eventually I plan to put mine in the ground, but they can be grown in containers.
You have a pineapple plant!
More things to know about growing pineapples
Pineapples do not grow or fruit quickly. Growing a pineapple this way will take 24 months to fruit, and another 6 months for the fruit to develop. Plus one plant grows one pineapple, so you won’t be inundated in pineapples.
Another thing to know about pineapples: they take most of their nutrients through their leaves, not the soil. Feeding with worm castings, soluble seaweed solution or another natural feed is better than synthetic fertilisers which may burn the leaves and damage the plant.
Finally, you might come across information that tells you that you don’t need to bother getting the pineapple head to root before planting, and you can simply stick the freshly cut head straight into a pot or in the ground. Personally, I love watching the magic of roots appearing right before my eyes.
That would be lost if I simply stuck the head in some soil, which is why I prefer this method.

Now, doesn’t that just make you want to head to the shops to buy a pineapple?!
