one other thing - they grow their ananas in peat and pine bark. They love the acid. The mixture is very important as it provides a bromeliad growth environment. These plants are being readied for potting after they cut the roots off. Once established again they will be packaged for shipment. I watched a truckload being loaded to go to a HD distribution point. Strangely I don't think I ever saw pineapples at Home Depot.

Why do they cut the roots off? It's easier to plant them that way and the plant will have a root system used to the pot.
