How long do artificial wreaths last? That depends. If you use artificial wreath for indoors, artificial wreath for windows, then it will last around 3 years or longer. If you use  artificial wreath for front door, artificial wreath for grave, artificial wreath for funeral, artificial wreath for cemetery, then the wreath will more likely be damaged by hot sunlight, by raindrops, by strong wind, etc.. In this case,  artificial wreath for outside will only last for 1 to 2 years. So, the lifetime of artificial wreath, it depends on the surrounding environments.  In this way, I believe you could understand how to store artificial wreaths.
