Q.Growing pineapples from tops
Your article or any other books I have consulted does not tell what to do with the plant once it gets large enough to be root-bound. Move it to a larger pot? How often? Place in ground? Mine is about 2-3 yrs old and is in a 5-gallon bucket. It is ready for the plastic bag to grow pineapples routine.
If it is OK to put in ground, what do I use for preparing soil if necessary? What is lowest temp it will accept? I live in So. Cal. so not usually very cold.
Your Pineapple plant is best left in a container or pot, and kept warm year round.
Here is more information for you.
