Hi Victoria, welcome to ATP and hope we can help. Need more info, though!
A few more pictures, showing the whole plant and the surrounding area would help. It is in the sun or shade? Under a tree?
Do you know what kind of plant it is? From the picture it looks like it could be anything from a bromeliad to a yucca, agave or a ginger. If you have an older picture of when the plant was healthy that would be helpful, too.
Also what part of the world do you live in? Your climate conditions right now could be affecting the plant.
