Well, you may think it's not over-watered, but over-watering means a different thing with succulents than it does with other plants. That soil will retain water; it looks very peaty. For a succulent, soil being water-retentive is a bad thing. It needs new, well-draining soil (a lot of well-draining ingredients like pumice or perlite added to the present soil mix). During waterings, the water should run right out the bottom of the pot in nothing flat--this would indicate you've got a good, well-draining mix.

I recommend you do some searches at this forum for jade plant advice, and you'll come up with loads. The problem is usually either over-watering and/or inadequate light, because plants kept indoors usually aren't going to do too well. And when putting it outside, always be careful to acclimate it to the new light; putting a plant directly in strong sun will often lead to its getting burnt. Was it in this kind of condition before it was put outside?

Thank you so much for your reply post. Her plant was beautiful before. Then she changed the soil and used 1/2 cactus soil, and half potting soil. She read that is how you were suppose to do it, I will go and quickly change the soil. Thank you again! I will do the searches.

Cactus soil, as it's sold, is never well-draining enough, sadly; it's just not quite as cruddy and peaty as, say, Miracle Grow potting soil. Supplementing it with a lot of well-draining ingredients is always a good idea. I'd fix up some nice well-draining soil, hold off watering again for a bit, and repot, and the plant will tell you if it needs to be watered. The leaves will have just a slight softness to them, rather than their usual firm feel, and then you can water. I'd probably watch over the plant a bit and not stick it in strong sun just yet, and then slowly acclimate it from the shade (outside shade, not inside, I mean) to greater sunlight gradually. I would not keep it inside the house while it recovers, because inside the house probably won't be enough light, and inadequate light is another problem in itself.

That plant looks like it's on its way out - there's no shame in that, as plenty of us have done the same (I've even killed one jade recently). Let me know if she needs more and one of us jadenistas will send her some more.

Candy,

Let me know via my handle (click it and you'll see an email option), but I was going to start some skinny jade trunks on their way to becoming jade plants - I can pick a particularly nice one for your daughter and send it to her the next time one of us is in the States.

It's never too early to inculcate your child with lessons on the joys and pitfalls of succulentism. I'm happy to see you're taking this rite of superior social behavior and advancement of aesthetic horticulture seriously.

I would cut it down to the next set of leaves and re-pot it in a very, very loose and good draining mix, one that the water runs right through, and set it in partial sun. Do not water until you see some new growth. It may or may not save it.
