1) Light garlands: decorate trees, bushes, or fences with bright lights. Use warm white lights for a cozy atmosphere or multicolored bulbs for a festive mood.
2) Winter figurines: Place glowing reindeer figurines to create a fairytale atmosphere.
3) Decorate trees: Hang Christmas balls, snowflakes, or tinsel on branches. A fir or pine in the garden is perfect for an outdoor Christmas tree!
4) Lights: Use garden lanterns to illuminate paths or flower beds.
