To attract good bugs into your garden, introduce host plants for them that will provide pollen and nectar. In addition, plants that offer shelter also encourage them to visit your garden. Zinnias attract beneficial insects to keep the pests out. In addition, they also increase pollination activities to increase the yield of squash, beans, cucumbers and other vegetables.
Mint, fennel, daisy and chamomile flowers attract predatory wasps and hoverflies. Thyme, rosemary and other low-growing plants offer shelter for ground beetles. Sunflowers also attract pollinators into the garden. The aim is to create a complete natural ecosystem in your garden that will keep pest damage to a minimum, increase pollination and bring huge harvests.
Now that you have a list of plants that repel vegetable garden pests to choose from, grow some of these in your garden to bring diversity and keep the pest population down. With these pest repellent plants you can naturally ward off pests without the need to resort to chemical means. Chemical pest control isn’t good for your vegetables or the environment and should only be practiced in severe conditions if all other techniques fail.
