Prevent weed spread: industry and recreation

Nursery and aquarium businesses

You can prevent the spread of weeds if you work in the nursery and aquarium businesses in the Northern Territory (NT).

If you work in a nursery or aquarium business you should know which plants are declared weeds so you can remove them from sale and report them to the Weed Management Branch.

You must do all of the following to prevent the spread of weeds through nursery or aquarium trade:

  • your sales staff must be able to identify declared weeds and suggest suitable alternate species to customers
  • remove all declared weeds from sale
  • destroy weeds and their seeds on site to avoid their spread
  • be aware that some plants from gardens and aquariums have become invasive weeds, including lantana, neem and cabomba
  • keep potted sales stock weed free, especially when sending orders to remote locations
  • closely monitor plants grown from seed to be sure that contaminants are not declared weeds
  • promote non-weedy garden plants through Nursery and Garden Industry Australia's Grow Me Instead program.
