The amount of sunlight each plant needs varies. According to Southern Living, most full-sun plants require 6 to 8 hours of sun a day, while some full-sun and part-shade plants need only 4 to 6 hours. Part-sun and shade plants can tolerate conditions with little sun exposure.
In a hot climate, plants may tolerate less sun, meaning that full-sun plants may need only 6 hours. Plant owners can watch their yards to closely acquaint themselves with area sun and shade patterns. With potted plants, leaving plants in their pots for two days is an effective way of observing how each one handles the sun in any chosen location.
