Harvesting Pineapple

Question

When I cut the pineapple from the stem do I need to trim the stem back or treat the stem with something to stop from rotting

Answer 1

Experts say you should leave an inch of stem on the plant. I'm not seeing any research that suggest the remaining stem should be treated with anything. Unless you see signs of problems with the plant, it should dry up and be fine. On the other hand, if the remaining stem shows signs of rot, you may have other problems. Here are links to a couple of articles that should help:
