Is morning sun better than afternoon sun?

Most plants requiring either part sun or part shade do well in filtered light for most of the day, or direct sun during the morning or afternoon.

Is afternoon sun considered full sun?

“Full sun” definitely means at least six hours per day, but some plants such as vegetables really need eight to ten hours per day. “Partial shade” implies that the plant should be protected from the sun during the afternoon. “Shade” does not mean pitch black, of course.

Is late afternoon sun good for plants?

In general, steer clear of plants labeled partial shade for areas of late afternoon sun. These plants usually enjoy the cooler morning sunlight but wilt quickly in the intense afternoon heat. Consider a plant’s water needs carefully before planting.
