The image shows a potted plant that appears to be in poor health. The leaves are drooping and the soil appears to be dry and devoid of moisture.
The first step in fixing this issue would be to make sure the plant is receiving enough water. This can be done by watering the plant regularly and making sure the soil is moist but not waterlogged.
Another issue that could be affecting the plant's health is a lack of fertilization. Fertilizing the plant with a balanced fertilizer can help to provide it with the necessary nutrients it needs to thrive.
Lastly, it is possible that the plant is not getting enough sunlight. Move the plant to a location that gets plenty of sunlight and make sure it is getting enough light to photosynthesize.
It is also recommended to prune the plant to remove any dead or damaged leaves and branches to promote healthy growth.
In summary, the plant is likely suffering from a lack of water, fertilizer and sunlight. By addressing these issues, the plant should start to look healthier and thrive.
