Instead of buying expensive chunks, buy a whole ripe pineapple and use every part.

Pineapple leaves

Twist off the green top and pull off three layers of the outer leaves from the bottom. Throw those in the compost bin. Let top dry for a few days, then place in a pot with soil. Keep in full sun and water the top occasionally, keeping the soil barely moist – this is a bromeliad, so no need to overwater. Your pineapple will bloom and produce a pineapple in 12-18 months.
