Yep, got one sitting on the heated bench as we speak. As Richard said they do take a bit of time to get the idea.
- What I did was cut the top of and dusted with either flowers of sulphur or rooting powder - can't remember which, but it was for the anti fungal properties rather than the rooting property
- Sat it on a half pot that was 2/3 gritty compost and topped off with Cornish grit
- Put a couple of ties over it just to stop it moving ans stuck it out of the way so I wouldn't be tempted to keep trying it.
The centre died off in a couple of places and these were pulled off when I potted it up just before Christmas and it now has two "pups" growing from it and I just keep it warm and moist and weight for my own pineapple to form ...
