The window first.
The plant second.
An empty corner isn’t always the right home for a plant. Start by watching how the light changes throughout the day.
Read the note
Notice where direct sunlight falls in the morning and afternoon. A spot by the window and a corner further inside the same room can offer very different conditions.
Before buying, check the light requirements of the particular species. Scorched leaves or stretched growth after a move may mean the position needs adjusting. Introduce brighter sunlight gradually.
