Why is my plant dying?

Question

It is only a month old, but it is dying. It was outside on the porch. It got sheetrock dust on it. I washed it off, but didn’t help. Brought it inside, didn’t help either. What do I do?

Answer 1

Your plant may need to be watered more often. A container plant outdoors will need daily water, even twice a day during hot weather.
