Evergreens are a rather hardy bush and easy to grow. Make sure you get the type that will grow best in your planting conditions like lighting and space requirements.
Evergreens are great bushes for looks and privacy. Make sure to keep on top of watering and make sure to fertilize in fall and summer with a fertilizer spike.
Some evergreen bushes are prone to fungus attacks. These are usually just cosmetic, and the plant remains healthy overall. Otherwise the only care they usually need is pruning.
