Hi there I consider myself a very fortunate jade owner. I have one, that is a cutting that is about 18 years old.
I had another just as big from the same original plant .. That I lost a few years ago. I had moved it, and it started losing tons of leaves, I never over watered, but the stems would get squishy and shrivel and whole branches fell off.
I asked a nursery and they said it was a disease. To keep it away from the healthy ones. WEll I dont know about that, But I do know that the one remaining is gorgeous. Cant hardly move it. it lives on the floor infront of our bank of sliders to the deck. All year round. Cold and hot, I leave her be.
Gets lots of sun and bright light. Are the leaves on your Jade hard and shiny or are they soft?
Do not soak it. and then drain, They dont like to be that wet. I water mine sparingly, about every 2 weeks.
NEver soak it. I will download a piccie of Jada! I Good luck!
