Is it possible to sprout a pineapple top? How do you do it?
Yes. This article will help: https://www.gardeningknowhow.com/special/children/planting-pineapple-tops.htm
I planted a pineapple top about 2 months ago. It has developed roots and the leaves or spikes on the bottom and middle of the plant are strong and green but the small spikes emerging from the core are brown and dried up and are easily pulled. Is my plant dying? I only water it when soil becomes dry and I mist the plant occasionally. I have it in a south facing window because it's winter right now where I live, so I put on the grow lights after the sun goes down to provide more light. Could this be "heart rot"?
I don't think it is heart rot as heart rot affected plants would be yellow in color and would smell badly.
You may be underwatering. While it needs to dry out some between waterings, make sure it is not drying out completely. Best way to do it is to check the top of the soil regularly. When the top of the soil feels dry, then water until water comes out the bottom of the pot.
Another possibility is that the plant has a fungus. Treat it with a fungicide as a precaution.

After pineapple is harvested, what happens to the plant? Do I get more pineapples from the same plant?
Pineapple is in the bromeliad family, and like its cousins, it bears fruit once, then dies. However, you can plant the top of the fruit to grow a new plant. https://www.gardeningknowhow.com/special/children/planting-pineapple-tops.htm
I didn't find an answer as to when to pick pineapple, and do not want to pick too soon. I don't know what info you want. It's a direct question. I just want to know when pineapples are ripe enough to pick?
1/3 or more of the peel should be yellow.
Then the fruit can be allowed to ripen off the plant at room temperature.
The time it takes for a particular plant to produce ripe fruit depends on the variety, the climate and care.
After a pineapple is picked, should the remaining stub be cut off the plant or left intact?
You should cut the Pineapple from the plant with a sharp knife close to the base of the growing site. Leave about 1 inch at the base of the Pineapple as you cut.
Try to avoid damaging the plant during harvest.
Check the main plant for more small plants or ratoons as these will develop into Pineapples.
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. Thanks, Elaine
Your Pineapple plant is best left in a container or pot, and kept warm year round.
