Ficus aurea: Strangler Fig1
Often starting out as an epiphyte nestled in the limbs of another tree, the native strangler fig is vine-like while young, later strangling its host with heavy aerial roots and eventually becoming a self-supporting, independent tree. Not recommended for small landscapes, strangler fig grows quickly and can reach 60 feet in height with an almost equal spread. The broad, spreading, lower limbs are festooned with secondary roots which create many slim but rigid trunks once they reach the ground and take hold. They become a maintenance headache as these roots need to be removed to keep a neat-looking landscape. The shiny, thick, dark green leaves create dense shade and the surface roots add to the problem of maintaining a lawn beneath this massive tree. The fruit drops and makes a mess beneath the tree.

Use and Management
Easily grown in full sun or partial shade, strangler fig can literally be planted, watered a few times, and forgotten. A variety of soils, including wet, will do, and strangler fig is moderately salt-tolerant. More often than not, large strangler figs were existing trees, not planted. Seeds germinate easily in the landscape allowing the tree to invade nearby land.
Propagation is by seed or cuttings.
Primary pests are aphids and scales followed by sooty mold.
No diseases are of major concern.
