How Do Weeds Spread?

Understanding how weeds spread is an important part of knowing how to control them:

  • Water: Some seeds can float, so rain and surface water runoff can transport seed long distances. Flooding rivers can move large quantities of seed very easily.
  • Wind: Wind can carry seeds over large areas. Weeds dispersed by this method often have light fluffy or even winged seeds that can easily be blown around. In some cases the whole plant can be blown by the wind.
  • Animals: Mammals and birds can carry all sorts of seeds on their bodies. Some weeds have hooks, spines or burrs to help them stick to animal hair & fur. Some seeds are also eaten and excreted out at new locations. These seeds have adapted to pass through the digestive system unharmed.

Some types of weeds require treatment at certain times of the year, while others can be treated any time. Some require only spot-treatments, and some require whole yard treatment.

Safety & Tips

It’s important to keep yourself safe while treating weeds:

  • Always read the label before using the chemical.
  • Wear thick gardening gloves at all times.
  • Wear appropriate clothes for outdoors – at least long trousers, hat and boots
  • Ensure correct ratio of water and chemical is mixed
  • Avoid windy days
  • Spray in the morning while there is a little moisture on the lawn
  • Avoid rainy days
