Wattles and bacteria

Bacteria called Rhizobium can grow in association with wattles. They can be seen as little bumps on the roots, called nodules. This partnership enables the wattle to absorb the essential nutrient nitrogen from air spaces in the soil. Wattles are able to obtain this nitrogen and use it to make plant tissue. This is why wattles are able to grow well in otherwise poor soils.

How can humans make use of this?

Wattle you know wattle you do?

  • Pull up one of those wattle seedlings you will be growing and look for nodules
