Answer: When you harvest the hips, just make sure they look healthy and complete. If there are any signs of disease, or any insects, discard them. Rose hips are normally harvested in the late fall, or as soon as they've turned a reddish color. If yours have been left out in the weather, you should expect to find some that have deteriorated, but those that look good should still be safe to use. Avoid using hips from plants that have been sprayed with pesticides.
