Weed Potential
As a weedJapanese Honeysuckle is highly invasive in regions where rainfall exceeds 600mm (2ft) annually infesting habitats that include rainforest, bushland margins or moist-gullies and along water courses. It twines into shrubs and trees with stems up to 15m long forming a dense habit that reduces light to the host plant.

It also spreads across the ground rooting at the nodes inhibiting the development of native tree or shrub seedlings and preventing ground flora from growing. It grows in well drained fertile moist soils and tolerates dry periods once established and prefers a semi shaded to open sunny position. The seeds are dispersed by birds or water and in soil and vegetative material is dispersed in garden waste.

Controlmethods include physically digging out seedlings and small plants when the soil is moist checking that all the roots and pieces of stem are removed. Fruiting branches should be bagged and removed off site then destroyed.

Large plants can be cut or drilled and painted / injected with a non-selective herbicide along the stems or in the woody crowns. Young plants or seedlings may be sprayed with a non-selective herbicide during spring while the plant is actively growing. Follow up spraying will be required to eradicate accumulated seeds in the soil.
