Winter in South Gippsland; the air is chilly, the rain is frequent, and Bridal Creeper is growing at a rate of knots!
Please be vigilant in controlling new outbreaks; keep a lookout underneath trees where seeds have been spread by birds. All underground tubers need to be removed in order for manual removal to be fully effective. Tubers can grow at some depth under the soil therefore using a small mattock to get leverage is the best way to go. All removed material should be double bagged and disposed of appropriately. Removed tubers have been shown to survive even without light for 2 years, therefore correct disposal is important.
For larger infestations, foliar spray using Brush Off (off label* in Victoria) from June to August up until flowering and prior to fruiting. If using Brush Off, care must be taken to avoid killing surrounding native vegetation.
Although Bridal Creeper is relatively common in Victoria, there is still potential for further spread. Active control will reduce the chance of spread; and protect vulnerable native plants and animals in the process. Now excuse me, I'm off to kick some (Bridal Creeper) butt!
Off Label * In Victoria off label use (not exceeding the maximum rate on the label) is permitted except for restricted chemicals requiring an ACUP e.g Grazon. Off label permits can be applied for at the DEPI or Australian Pesticide and Veterinary Medicines Authority. Off label use can be quite complex and it is recommended that enquiries be made in the first instance with the DEPI. The DEPI website does have good info on chemical use rules go to; http://new.dpi.vic.gov.au/agriculture/farming-management/chemical-use
