So from what I have read the minimum time to flower is about two years and temperatures play a big role in that. You can force the flowering stage with the gasses that apples produce (see comment thread from one of my older posts) but in my case it took about 4.5+ years for mine to start to flower. After the process begins it supposedly takes about 6 months to have a fruit mature enough to harvest. I only stuck mine in succulent dirt and sort of bound it in a plastic pot that was slightly too small and also watered it like the rest of my succulents. I essentially stressed it a bit with drying it out between watering and then soaking it when I did water it to get it to reach deep for the water. Liquid succulent plant food occasionally. I am a dick to my plants but they seem to do decently and I have no idea if any of that is really a good way at all.
