Many years ago I was told about growing pineapples, so I had a go! I used to slice off the rosette with a few centimeters of the pineapple attached. Then get a plant pot more or less the circumference of the pineapple piece I cut off, and filled it with compost to within a few centimeters of the top. Covered the compost with a thin layer of grit-sand then watered just enough to wet it - don't saturate the compost. I pushed the rosette firmly onto the compost and placed it on the kitchen windowsill. Hey presto, it rooted! So I potted it on. Many more followed!!
