Hello everyone. I am new here. First of all forgive any grammar or generally language mistakes I make since English is not my mother tongue. I joined mostly because my favourite plant looks seriously ill. I would really appreciate any help I can get!!!!!!! My plant is â€œPortulacaria afraâ€, also known as â€œElephant's Foodâ€ or â€œElephant Bushâ€. It is approximately 5 years old but I have it for 4 years and the last 2 years it is growing really fast. Especially from this spring until 1 week ago it grew from 70 centimetres (2.3 feet) to 1 meter (3,28 feet). It is planted still in its original pot which is a clay pot 12 centimetres width (4.72 inches) and 9,5 centimetres height (3.74 inches). I was in the process trying to figure out of this is normal or if I should cut it down a bit but I donâ€™t have the heart to touch it. I thought nature knows what itâ€™s doing. I donâ€™t want to treat it as a bonsai. I want it to grow naturally. But before I even started my research about it . . . it started . . . The longest branch, which is 1 meter long (3,28 feet), started losing its leaves dramatically. Just by touching it a little bit tenths of healthy leaves are falling. The branch has started loosing its leaves from the top and gradually dying downwards as if something is eating it. Now I have done my research about it and I will tell you what is NOT wrong with it first. 1) I checked very very thoroughly all the branches and soil and it is not root mealy bugs or any other bugs. 2) I havenâ€™t moved it and no temperature or light condition has changed in its environment. 3) And last, I havenâ€™t over watered it!!!! I water it exactly the same way for 4 years now and it has never complained. The only time it got in a bad shape was 3 years ago when I moved to a new apartment. It got shocked with the change of light, change of temperature and everything so it lost ALL its leaves and was completely naked for a couple of months. BUT the branches were very healthy and kept on growing till they started growing leaves and thrived again. Now it is different. Now the branch is dying. I also noticed during these 4 years some other branches that are wrinkly and thin in some of their parts (not the entire branch) and donâ€™t look particularly healthy in my opinion, but they have leaves and the upper part of these brunches is green and healthy and still growing. I donâ€™t know what to do. Should I replant it? Should I cut it down? I donâ€™t want to cut it down really . . . but if it stops it from perish I will do it :s Please please please help me! This plant is my pride and joy of all my plants. It is also the very first plant I ever cared for and the reason I started being interested in plants. Here I posted some pictures so that you can get a visual of what is happening to my baby!
