There are many ways we can use plants in the garden to aid in our quest to produce the best vegetables we could possibly eat. By making use of their beneficial qualities, we can improve the soil and plants around them, and hopefully reduce the need for insecticides.
Insectary plants are those plants that have some important interaction with insects, whether it is to attract beneficial insects or to repel pests.
Insectary plants to repel pest insects
Highly aromatic herbs will help to deter pest insects, but it is best not to plant large growing perennials or ones that form a dense mat too close to your veggies as they can compete with crop plants. We mostly use them as perimeter crops or place them in pots around the patch. Some are crop plants eg. Onions or annual herbs, so these can be planted amongst other vegetables.
* Asterisk denotes plants that have both attractant and repellent qualities
