Dear forum experts, I'm reaching out for your help with my ficus benjamina. I bought it from Home Depot around July 2020 with a decent amount of foilage but also signs of leaf loss (withering and falling leaves), though nothing alarming. At home it continued to lose leaves, and I kept hoping it would eventually habituate to its new surroundings. Instead the leaves continued to fall, and I observed both green leaves falling, as wells leaves that first withered and then fell as dried, dead leaves. I could see new leaves starting to grow, but the green tips would turn brown and dry before actually growing into a leaf. Then the branches also began to die, with the bark becoming papery and seeming to separate from the wood beneath. I've been pruning off dead branches as I go along, but now the "dieback" has progressed to the main trunk and I think something more needs to be done to save my tree! Note that I have also observed a few scales (black round circles on leaves) and also mealybugs (white and powdery with scaly/shell-like back) which I remove promptly and I believe I've kept this under control, i.e. right now there aren't any of these pests on the plant. I've also found a single centipede in the soil before and a couple of ants as well, but no infestation. I've checked the soil and the plant is not rootbound. I have been very careful not to overwater -- the tree has never sat in water, I use a skewer inserted in the soil to check humidity and water as needed, and the roots look healthy and are pretty much unchanged from when I got the tree. The tree's water uptake seems to be decent as well, as the soil doesn't stay wet after watering. Dead leaves New leaves that were trying to grow but have started turning brown and will probably die Dead branches - notice the ripples on the bark, those sections are all papery and the outer bark feels separated from the tree beneath. The point of progression of branch/trunk death (i.e. ripples on the bark, papery-feeling), and the transition to firm and healthy-feeling trunk. The skewer in the photo is pointing to an area of papery bark. Note that those black lines/spots were present on the tree since purchase and haven't really changed; they emerge close to the end of the main trunk (4/5 of the way up) and extend to the end of the three main branches, and are not present on the newer/younger branch shootings. Thank you for your help!
