[loostep]

I have a large Jade tree, that wilted last week and has fallen over, I have moved it to a position where it is not so much in the sunlight and have given it a good drink, it doesnt seem to be getting much better though.
Any advice would be great thanks.

Loostep, jade plants don't usually wilt from lack of water, rather the opposite, and they certainly like sunshine, so that's not the problem either, probably. If you cannot see any signs of pests on or under the leaves which might be killing the plant, I would think it's too wet. If that is so, you could try taking it from the pot and letting the soil dry out. You could root a leaf or two just in case you do lose the plant. If the stalk or trunk is soft or even mushy, it may be too late.
Even pot-bound jades do not usually wilt. You would have to leave them for more than a couple of months without water to see that effect persisting after giving them water, in my experience, and then in a few days definitely they would recover. However, if you have not overwatered, and the plant is not in too large a pot and surrounded by damp soil, could it just be keeling over because the pot is too small?.
