A member of the American Association of Professional Technical Analysts, Kristin Hetzer has served as a principal for Royal Palms Capital, LLC, since 2005. Outside of her professional responsibilities, Kristin Hetzer enjoys outdoor activities such as hiking and gardening. Gardeners must consider their hardiness zone, a designation based on a region’s lowest average temperature when selecting plants and crops. Many annuals are sensitive to colder weather and must be protected from frost. Cooler air temperatures can also wick moisture from plants and damage their leaves.
