Jacob D - Your pineapple should be okay outside if you protect it from frost. I started planting them outside a couple of years ago when we bought this house (zone 9, Florida) and they have lived through two winters. They are in a fairly protected place, southeast corner beside the back porch, morning sun only, and we are getting our second pineapple. The first one was delicious! I totally ignore them except to cut off the tips of the branches so they don't puncture the porch screen. They are in dense, sandy soil with absolutely no nutrients. This is one tough plant! I will throw a sheet over them if it gets down into the 20's.

The only problem I have with them is I can't bring myself to throw a pineapple top away. We just cut the tops off and I let them dry for a few days, or a few weeks if I forget about them on the top of the fridge, then I just stick them in the ground. They are all thriving, which is unfortunate as I now have five in the ground, and two more in pots because I ran out of space beside the porch. Now I am going to have to dig more holes in the yard to plant these.

I only wish my roses were doing this well...........
