Hello...SOMEONE PLEASE HELP! I bought my beautiful Pachira tree 4 years ago. It has grown into a magnificent 7ft tree which I adore. Unfortunately about 3 months ago the tips of the leaves began to turn yellowy-green and then brown and then they fell off. The tree has 4 roots and I have noticed one of them had become a paler green and has black spots/patches and is less firm at the top however, the root is still firm. I do not over-water my pachira. What can I do????....I would hate to loose her as she brings so much pleasure to me...PLEASE HELP. Reply to forum or direct to misteracj@yahoo.com
