Hi there! Thank you so much for reading. For months i have been faced with this problem. The stem of my plant(Idk whats the name of the plant) have been appearing black at certain parts of the stem. The colour of the stem has discolored. One stem looks healthier while the other looks pale.

Other than the stems problem, the leaves seems to have w insects. They are alive. They are so tiny. Whenever there is a swarm of white insects on an area of the leaves, the leaves seems to have just stayed at the same size. For example, when there is a new shoot coming out , and these white guys infects the shoots, the growing progress stalls. The leaves turn yellow.

Other than that, my whole plant have wilted... Leaving only a portion of the leaves. These leaves are also infected. What i am doing now is basically use soap water to get rid of them.

May i know what other things can i do to get rid of them?
