I wasn't the person with the question about sprouting pineapple seeds. I was answering somebody else.

For vegetative propagation, instead of cutting off the crown, twist it off from the fruit. It will come off leaving all the flesh behind. Peel the old leaves. Nestle just the exposed stem directly on top of loose soil in a pot, water it just enough to wet the top of the soil, and keep it as warm as you can. Let the soil dry between waterings, which should be very light at first, since roots have not penetrated the soil mass. This method leads to a lot less trouble, rot and fungus than cutting off the top, leaving fruit to mold while sprouting. In most areas, a heat mat would be of great benefit.

Rooted pineapple plants will grow in full Arizona sun and heat. Unlike most other bromeliads, they are not sensitive to copper. They fruit plentifully in a 15-gallon / 57 liter pot, but can fruit in as small as a 5 gallon. I start tops directly into standard 1-gallon / 3.78 liter black plastic nursery pots because I give most of them away. A fresh top could go directly into the ground in a warm area, or into the final container. They are monocarpic like many Agave; after fruiting, the rosette dies, and offsets take over the work.
