Nasturtiums as a trap crop?

Nasturtiums are excellent trap crops because they attract pests like aphids and others away from desired plants, acting as a sacrificial decoy to protect crops such as milkweed and vegetables. This practice is a form of integrated pest management (IPM) that uses a trap crop to deter pests, reducing the need for chemical pesticides.

What are Trap Crops?

A trap crop is a plant that is used to lure pests away from a different, desired crop. Nasturtiums serve as a sacrificial trap crop by attracting pests like:

Aphids: Nasturtiums can be heavily infested with aphids, which are then easier to remove.

Slugs and Snails: These pests can be attracted to nasturtiums, making them easier to control.

How to Use Nasturtiums as a Trap Crop

Plant Nasturtiums: Sow nasturtium seeds directly in the ground near the plants you want to protect or keep potted.

Monitor and Manage: Regularly inspect the nasturtiums for any pest infestations.

Dispose of Infested Plants: Once pests have concentrated on the nasturtiums, you can easily remove and destroy the infested plants

Other Benefits of Nasturtiums

Edible: The flowers and leaves have a peppery flavor and can be used in salads.

Attract Beneficial Insects: The nectar-rich flowers attract pollinators and other beneficial insects to your garden.
