Spanish moss is an easy air plant that requires little maintenance. Hang them on a wire or place them over a basket or pot outside as they love the full sunlight. I tend to use water hose to spray water on them every other day but they can go without water for days. When the moss received watering, they will turn green per picture #2 and in the late afternoon, they will turn back to silver when they are completely dried out. Live Spanish moss can be used for decorations and add on top of orchids or for flower arrangements and mulch. Some benefits for growing moss: The moss prevents weeds from growing and maintain soil moisture. As these mosses break down, they will add nutrients to the soil. They are a great addition to a compost pile. This listing is for a 2-Quartz Ziploc slider bag size. The package of moss may be shipped in bigger size to ensure the moss does not get suffocated en route. For bigger sizes, pls message me.
