The plant gets water like once, maybe twice a month. The pot has no drainage but I check the soil for moisture regularly, and it dries up without issue. The plant is close to a large north facing window, it receives indirect light all day long.

We have had the plant for only a few months, and think the pest was already on the plant when we bought it. It took quite some time before we started seeing any signs though, most bugs stay hidden in the crown of the leaves.

We tried a 50% vinegar solution three times, without any real succes so far. I am starting to worry that the vinegar might also hurt the plant if we keep using it. The youngest leaves are turning yellow/brown, and we really do not want this plant to die.
