How to Grow Pineapple From a Grocery Top
Share
You paid for the pineapple at the store. The top is sitting right there. Most people throw it in the trash. That crown is a free plant waiting to happen.
Growing a pineapple from a grocery top works in Florida, and it is easier than most people think. Here you will learn exactly how to prep the top, root it, plant it, and keep it alive until it fruits.
What You Need Before You Start
- One fresh pineapple with a green, healthy crown
- A sharp knife
- A glass or jar of water
- A container or ground spot with well-draining soil
- Patience. This plant takes 18 to 24 months to fruit.
Step 1: Prep the Pineapple Top
Twist the crown off or cut it about an inch below the leaves. Remove the bottom leaves until you expose about an inch of bare stem. You want to see the small brown nubs along the stem. Those nubs are your future roots.
Let the cut end dry in open air for two to three days. Skipping this step invites rot. Do not rush it.
Step 2: Root in Water First
Set the bare stem in a glass of water so only the stem is submerged. Keep the leaves out of the water. Place it near a bright window. Change the water every two days to prevent mold.
White roots should appear in two to four weeks. Wait until roots reach at least half an inch before moving to soil. Rushing to soil before roots form is the number one mistake new growers make.
Step 3: Plant in the Right Spot
Pineapples want full sun and well-draining soil. Sandy Florida soil works well here as long as you add some compost to hold moisture. A raised bed or large container works fine too.
Plant so the base of the crown sits at soil level. Do not bury the leaves. Water it in well, then back off. Pineapple plants in Florida only need water every seven to ten days once established. Overwatering causes crown rot and will kill it fast.

Step 4: Feed It Right
Pineapples are bromeliads. They feed partly through their leaves. Once your plant is established, use a balanced slow-release fertilizer every six to eight weeks during the growing season (March through October). You can also spray a diluted liquid fertilizer on the leaves directly.
Do not over-fertilize with nitrogen. Too much nitrogen pushes leaves but delays fruiting.
Step 5: Encourage Fruiting
Pineapples typically fruit on their own in Florida after 18 to 24 months. If yours is healthy but not fruiting after two years, there is an old trick. Place the plant inside a large plastic bag with a ripe apple for three to four days. The ethylene gas from the apple triggers flowering. Remove the bag after four days and check for a flower stalk within six to eight weeks.
Once you see a flower stalk, it takes another five to six months to get a ripe pineapple. Worth every bit of the wait.
Regrow Pineapple in Florida: What to Expect by Season
Fall and Winter (October to February)
Growth slows down in the cooler months. Your plant will not put on much size, and that is normal. Do not push fertilizer during this window. Just keep it alive and let it rest.
Spring and Summer (March to September)
This is when the plant takes off. Warmer temps and longer days push growth hard. Increase watering slightly during the driest spring weeks, and resume your fertilizer schedule. This is also when most pineapples in Florida will send up a flower stalk if they are old enough.

After the Fruit: What Happens Next
After the main plant fruits, it will start to die back slowly. But it sends up "pups," small offshoots at the base. Those pups are your next generation of pineapples, free of charge. Let them grow to about a third of the main plant's size, then separate and replant.
One grocery top can become a permanent pineapple patch over time. That is what Grow Food NOT Lawns is all about.

Key Takeaways
- Let the cut crown dry two to three days before rooting to prevent rot.
- Root in water first. Plant only after roots are at least half an inch long.
- Pineapples take 18 to 24 months to fruit. Plan for it.
- Pups from your first plant become your next harvest, no cost.
