I am growing pineapples in 5 gallon buckets (holes drilled in bottom for drainage). I removed the pups that were growing in between the leaves as my pineapple developed and reached maturity. Now that I have harvested the very tasty pineapple I noticed that there is yet another pup on the plant and it is getting to be quite large. Can I just leave this pup alone and expect to get another pineapple or do I remove it and pot it up as usual? And can I reuse the 5 gallons of soil for pineapples?
