In “Biological Weed Control” – DIY Garden Minute Ep. 73 – we want to teach you about this method of controlling weeds and where to find more information.

This episode is meant for any level of gardener who is looking for alternative ways to manage their garden weeds.

Weed Control

Any living organism that you don’t want in your garden and could have a negative effect on your garden or its health is considered a garden pest. Weeds are no different.

A weed fits this pest description and can be characterized as a plant pest that can eventually outgrow and take over your garden area.

Pests show up in your garden for many different reasons. Some seek shelter while others come hungry noticing that your garden provides tasty meals. Other pests are just short-term guests who pass through or decide to stay for a few days.

Generally, pest control is broken down into five different categories in a management system called Integrated Pest Management, or IPM.

The five control categories are:

  • Biological Control
  • Chemical Control
  • Mechanical/Physical Control
  • Cultural Control
  • Environmental Control

Biological Pest Control

Biological pest control refers to using living organisms to control all kinds of pests.

In this method of IPM, the natural predator of a pest is used to manage the situation.

General examples of biological pest control include:

  • Using parasitoid-wasps for aphid control
  • Using ladybugs to eat aphids
  • Using goats to eat ivy or blackberry
  • Using a praying mantis to control either caterpillars or aphids

When biological methods are used for weed control there are multiple ways this can be used.

Examples include:

  • Growing other plants that will compete for the same space and resources
  • Promoting plants that actually seek out and harm weeds
  • Using insects or animals to prevent, control, or remove those weeds from your property
