Quick Answer
Twist (do not cut) the leafy crown off a fresh pineapple, strip the bottom 10 to 12 rows of leaves to expose 1 inch of stem, then let the crown dry upside down for 7 to 14 days so the cut surface forms a callus.
Once callused, suspend the bare stem in a small jar of water for 2 to 3 weeks, or plant it directly into a fast draining cactus mix. Keep it warm, bright, and lightly watered.
A home grown pineapple takes 2 to 3 years to produce edible fruit, but the plant itself is a striking tropical houseplant the whole time.
Choose the right pineapple
Not every grocery pineapple will sprout. Look for one with a healthy, deep green crown of leaves and no brown rot at the base of the leaves. The fruit itself should smell sweet and feel firm, not mushy.
Pineapples that have been refrigerated for long stretches sometimes lose their ability to root, which is why crowns from farmer's market or warm climate stores tend to do better than ones from a cold supermarket aisle.
Twist, do not cut
Grasp the fruit firmly with one hand and wrap your other hand around the leaves at the very base. Twist sharply. The crown pops off as a clean cone of stem, leaving the fruit flesh behind.
Cutting with a knife leaves a wet slab of fruit attached to the stem. That sugar packed flesh almost always rots before the crown can root, killing the project on day three.
Strip the lower leaves
Peel away the bottom 10 to 12 small leaves by pulling each one downward and off. You should expose roughly 1 inch of bare, woody central stalk.
Look closely and you will see small brown bumps along that exposed section. Those are dormant root initials, the spots where new roots will emerge once the crown is ready.
The callus phase: 7 to 14 days
This is the step most beginners skip, and it is the difference between a rooted plant and a rotting one. Set the trimmed crown upside down on a paper towel in a dry, shaded spot indoors. Leave it alone for 7 to 14 days.
During that time the cut tissue and leaf scars dry and form a hardened layer called a callus. The callus acts as a natural seal against soil bacteria and fungi.
You can tell the crown is ready when the base feels dry and slightly papery, not wet or sticky.
Method 1: water rooting
Fill a small glass or jam jar with room temperature filtered water. Rest the crown on top so the bare stem dips into the water but the leaves stay completely above the surface. A coffee filter or piece of foil with a hole can hold the crown steady if needed.
Place the jar in a bright window, but not in scorching direct sun. Change the water every 2 to 3 days to keep it oxygenated. Roots usually appear within 2 to 3 weeks, starting as small white nubs and lengthening into a fine network.
When roots reach 2 inches long, the plant is ready to move into soil.
Method 2: straight to soil
If the callus looks solid and you would rather skip the jar, plant directly. Use an 8 inch terracotta pot with drainage holes and fill it with a mix of 50 percent regular potting soil and 50 percent perlite or coarse sand. Pineapples hate wet feet.
Make a hole in the centre, press the callused crown into the mix until only the green leaves sit above the surface, and firm the soil around the base. Water lightly to settle the soil.
Place the pot somewhere warm (above 18 C / 65 F) and bright, ideally with at least 6 hours of indirect sun. Water only when the top 2 inches of soil dry out completely.
What to expect over 2 years
| Stage | Timeline | What you will see |
|---|---|---|
| Rooting | Weeks 1 to 4 | White roots from the base of the stem |
| First new leaves | Months 2 to 4 | Fresh green leaves from the centre |
| Mature plant | Months 6 to 18 | Wide, arching leaf rosette |
| Flower spike | Year 2 to 3 | Red and purple central flower |
| Edible fruit | 4 to 6 months after flower | Small to medium pineapple |
Care once it is established
- Light. At least 6 hours of bright sun. Outdoors in summer is ideal in warm climates.
- Water. Soak when the top of the soil dries, then let it drain fully. Never let the pot sit in a saucer of water.
- Feed. Half strength balanced fertiliser once a month during spring and summer.
- Temperature. Bring it indoors below 13 C / 55 F. Frost will kill it overnight.
Frequently asked questions
How long does it take to grow a pineapple from a top?
Roots in 2 to 4 weeks, a mature leaf rosette in 12 to 18 months, and fruit in 2 to 3 years.
Will my pineapple plant actually produce fruit?
Indoors and in cool climates, only about half of home grown crowns ever flower. Outdoor plants in tropical conditions are far more reliable.
Can I plant a pineapple top without drying it first?
You can, but the rot rate climbs dramatically. The 7 day callus phase costs nothing and is the single biggest predictor of success.
Does the pineapple need to be organic?
No. Conventional supermarket pineapples root just as well as organic ones.
