Want to add a tropical feel to your backyard instantaneously? Grow Spanish moss (Tillandsia Usneoides). This eye-catching plant that hangs from trees in the tropics and the southeastern United States can also be grown in other areas of the country. Simply hang a clump of Spanish moss in your outdoor or indoor garden and watch it grow.
Spanish moss is actually not a moss at all. Instead, it’s in the bromeliad (pineapple) family. It is an epiphytic plant that draws moisture from the air and from runoff from the host plant on which it’s growing. You can grow Spanish moss successfully in a dry climate, providing you water it regularly to ensure it stays sufficiently moist.

Water moss in hot, dry climates. Generally, Spanish moss requires no watering, if you live in a humid, rainy climate, as it will draw the necessary water from the air and surrounding plants. If you live in a hot, dry climate, however, such as California or Arizona, or you are experiencing such weather, you will need to water Spanish moss every day or every other day. Not doing so can cause the moss to go dormant.
Fertilize occasionally. Though Spanish moss generally doesn’t need any feeding, it can speed up growth if you spray the plant monthly in the spring and summer months with a half-strength solution of an organic liquid fertilizer, such as sea kelp or compost tea.
