Jasmine (Jasmine polyathum).
What does it look like?
This is an evergreen climber that grows up to mid-canopy height. The shiny, dark green compound leaves have seven opposite leaflets and new growth is tinged with red. It has masses of highly scented, small white tubular flowers, mainly in spring followed by occasional glossy black fruit.
Why is it a problem?
It forms impenetrable groundcover, smothering all vegetation to mid-canopy level and suppressing regeneration. It is spread by garden dumping and birds.
How do I get rid of it?
- Cut off foliage in trees. Leave to sprout and spray regrowth with 5g metsulfuron-methyl (600g/kg e.g. Escort®) +10 mls penetrant per 10 litres water, or 120mls Banvine® +10 mls penetrant per 10 litres water.
Control methods for climbing pest plants
There is a range of methods available to control pest plants. The following recommendations – which are only a sample of those available – are based on safe-use methods that have proven effective.
- Physical removal of the plant and all fragments to a land-fill is the best organic method.
- Slashing, mowing or otherwise removing plant material and then treating the stumps or regrowth reduces the amount of chemicals needed.
- Always apply chemical to cut stumps within 10 minutes of cutting.
- Spray is recommended for large areas. It is best to apply spray during spring to autumn when plants are actively growing. For gun and hose or aerial rates contact the regional council’s biosecurity team.
- Penetrant aids the uptake of herbicides – there is a range available, e.g. Pulse®, Boost®, Freeway, Dewdrop, Kiwi Buddy Uptake crop oil.
- Follow-up is always recommended until the seed source in the soil is exhausted.
Caution: when using any herbicide or pesticide PLEASE READ THE LABEL THOROUGHLY and follow all instructions and safety requirements.
