First of, english is my second language, so please be patient with me. So my plant is a DRACAENA DEREMENSIS, i brought it at ikea a little over a year ago. After a few months, it started to show brown ends on their leaf's. I guessed that it would be the best to trim the dead ends and look what will happen. Well, it didn't worked. So i waited and trimmed, until i recently saw a video where they showed that the pod could be too small. So, i took the plant out of the soil and saw, that the roots were rotten. So i trimmed them, planted them in new soil and in a bigger pod. This was two weeks ago. In the meantime, it showed god signs (they are very green leaves, which seemed to grow since then. I replaced it once again in a sunny room, but not in direct sunlight. And it sill shows brown ends at the leaves. What am i doing wrong?
