Here are some updates since the time I wrote this article last month on my own personal pineapple plantation (consisting of about 6 plants in a tight circle in the ground):
The largest, green pineapple shown in the first photo in my article continued to ripen nicely. Then one of the wild creatures in my neighborhood (presumably animal rather than human) discovered the pineapple and came to check its ripeness at night. Its first investigation of the fruit resulted in the pineapple stem getting broken, but not all the way off the plant. Then the beast began taking big bites out of the pineapple each night. Finally, when the pineapple was reaching a nice golden glow, the entire pineapple fruit disappeared! I wouldn't have minded so much if it had eaten all the fruit and left me the bromeliad crown to plant and grow as my second generation from the original pineapple, but I've not been able to find any trace of what had become a nice, large pineapple bromeliad top anywhere in my yard. Who knows, I may find myself pulling weeds in a far corner of the property some future day and discover a pineapple plant growing without any tending on my part.
The photo in my article that showed a pineapple in flower -- that flower has now developed into a fruit about 4 inches long and is still growing nicely (photo below). I will probably build some sort of wire enclosure around it as it begins to ripen to keep the marauding pineapple bandit away from it (good luck with that, you say?!)
The pineapple that I had started in the clay pot is now in the ground and doing well. I'll post a photo of it in another thread.
The new flower appeared above a white flush in the leaves, rather than the bright red I've seen before when the pineapples start to flower. The flower head also looks a bit different. It was also from a store-bought pineapple fruit, but it could have been a different variety of pineapple. I'll post a photo of it in another thread.
