How to Grow Pineapples as Houseplants
By: Julie Day
Who says you can’t have a taste of the tropics in your own living room? Pineapples are easy to grow as houseplants, and you can start one with a pineapple crown from your own kitchen.
Rooting takes a couple of months, and it’ll likely take 2-3 years to get fruit, but in the meantime you can enjoy the spiky tropical foliage and the fun of growing a tropical treat. Here’s how to root and grow pineapples indoors in your home.
Pineapples are a type of bromeliad, which makes them a cousin to Spanish moss and the colorful bromeliads commonly grown as houseplants. Like other types of bromeliads, pineapples are able to absorb some water and nutrients through their leaves in addition to their roots.
A mature potted pineapple plant will be several feet across and tall, and a mature plant will need a five-gallon planting container. It will take at least a year of growing to get a plant to this size. You can put the pot outdoors during the summer, but you need to bring the pineapple plant inside before the first frost of fall.
How to Root a Pineapple Crown
Follow these easy steps to get your pineapple plant started:
Step 1: Buy Fresh Pineapple
The next time you buy a fresh pineapple to eat, make sure to choose one that’s evenly ripe, with a nice healthy set of green leaves at the top. Avoid ones that are overripe or that have dead or sick-looking leaves.
Step 2: Slice Off Pineapple Crown
Using a sharp knife, slice off the top of the pineapple fairly close to the crown. Carefully cut away the rind and remaining fruit – it’s important to remove any fruit flesh that will rot later. Then, make very thin slices in the stalk, until you see a ring of brownish dots. These are the “root primordia,” the unformed roots that you’re about to grow.
Step 3: Remove Leaves from Stalk
Pull off some of the lower leaves on the pineapple stalk, exposing about an inch of bare stalk.
Step 4: Allow Stalk to Dry
Set the pineapple crown aside for a few days to allow the wound to dry. Pineapples are very susceptible to rot, so it’s important to dry out the cut end before planting.
Step 5: Plant Pineapple Stalk
Fill a 6” to 8” flower pot (clay is best, but any pot will do) with a light, fast-draining mixture – such as cactus potting mix – or a mixture of peat, sand, and perlite. If you like, you can dip the end in rooting hormone before planting. Plant the pineapple crown about an inch deep, gently firming the soil around it.
Step 6: Water Pineapple Stalk
Water the pineapple stalk very lightly, just enough to moisten the soil – a spray bottle works well for this. Put the pot in a bright window, and water the plant when it’s dry, just enough to keep it moist. Don’t use any fertilizer yet. To keep from over watering, some people put the pot in a terrarium, or in a lightly sealed plastic bag, to allow the plant to recycle its own water.
Step 7: Wait for Pineapple to Root
It’ll take about 1-3 months for your pineapple to root. To test the progress, very gently tug on the crown to see if it is taking hold in the soil. Don’t pull hard enough to break the roots.
Step 8: Repot Pineapple Plant
Once your pineapple has firmly rooted, it will begin growing new leaves from the center. At this point, you can repot the plant in a 10” to 12” pot, using a rich but fast draining potting mix. After about a year of growing, you can move it to its final home in a large 5 gallon planter.
How to Care for Your Pineapple Plant
- Growing More Pineapples: All of those new pineapples can be rooted to make more plants. When you harvest your pineapples, look at the base of the fruit for small baby shoots. Harvest your pineapple carefully, leaving these shoots to grow a little. They can then be gently removed and planted in their own pots.
