Weed Potential
As a weedMorning Glory is wide spread in high rainfall regions of Australia and is highly invasive growing in a variety of native habitats including woodlands, forests or along water courses and in disturbed landscapes.

Coastal Morning Glory (Ipomoea cairica) infests coastal dunes, water courses and rainforest margins. The vines have a fast growth rate forming stems that can reach into trees and smothering them cutting out the light of the host. They can cover large areas of bushland causing significant damage to ground plants shrubs and trees.

The vines are long lived up to 25 years and prefer an open sunny position on moist soils. Mature Coastal Morning Glory produce viable seeds within 1-year and both species have stems that root at the nodes.

Care should be taken as small fragments of the stems can form new plants. The seeds of the Coastal Morning Glory (Ipomoea cairica) are dispersed by wind and Morning Glory vegetation is dispersed in garden waste and soil.

Control methodsinclude physically digging out small infestations including the roots and stems that are in contact with the ground or the vine may be severed at the base and the foliage left in the canopy to dry out.

Larger plants should be cut at a height of 1m (3ft) from the ground and sprayed with a non selective herbicide. Fruiting stems of Coastal Morning Glory (Ipomoea cairica) should be cut and bagged where possible then all plant material should be removed off site and destroyed. Plants may be sprayed with a non-selective herbicide but follow up applications are required.
