Step 1: What do you need
-Pineapple, not too ripe, with a healthy rosette
-A good knife, a bread knife works fine
-A pot, you can be creative and use your imagination
-Soil, go for an easy-to-drain soil (ex.: for bonzaï or cactii mix)
Step 2: Cut the head
It's important to have a perfectly healthy rosette, reducing the risk of rotting and increase chance of success. Cut and keep the head, prepare the edible part for later.
Step 3: Prepare the head
Step 4: Remove some leaves

Step 6: Watch it grow and enjoy!
P.S.: In the future, I'll make an instructable about how to make a fruit of it.
