If top heavy, probably tying it? Either to stakes or pot itself. Heavier/larger pot probably won't help since to heavy plant-top will be 'blown over' and dislodged from potting mix. Maybe few large rocks at the base?

If it is too big for rocks , and you don't mind unpotting it, put a stick across the bottom the pot, with strings/wire wrapped around it extending out the bottom drainage hole. Use these to tie the plant upright, taking care not to damage stems. Alternatively, use small clamps on edge of pot to attach guy wires to the trunk..

If it were mine, I would do one or two things. I would pot it in a heavy clay pot, and if need be, trim the top so that it is no longer top heavy. For my tall cacti, I stake them, but with a Jade I would just cut it back.

pic of how I 'anchored' tall jade (I think it was 32" at the time) - not that good looking, but it held it in place. See the rocks at the base too (there was much more pruning done to it later):

I use 14 gauge wire to make a tie off system around the pot, where I twist loops in the wire and go around the pot. I then go from the loops to the trunk to support it on 3 sides. Here's a pic of a my freshly repotted gollum:

Thanks for the ideas. I think I'll have to tie it to the plastic pot and then go with an upside down pot in a larger pot as suggested.

I've been pinching it to encourage growth below so that I can start to reduce it by a wee bit at a time. I've been over-zealous in the past and as hardy as they are, I've managed to effortlessly severely stunt or kill many a jade.

oops. I responded early in the afternoon yesterday but neglected to hit 'send' =P

The wires are a great idea! I will go with large rocks for now but keep an eye out for a heavy suitable pot along with wire to keep it steady.

Thanks for the pics everyone!!! It helped a great deal, I was only putting one or 2 rocks strategically placed but they weren't nearly as big (or as heavy) as shown. I suppose that's why it didn't work all that well for me in the past, lol.
