Seeds, fertilizer and varieties abound, and flowers are more popular than ever, whether purchased as gifts or growing in the garden. National grocery chains, big box stores and online warehouses all sell the blooms by the stem and offer DIY tips and design workshops.
First of all, some of the pests marigolds help deter are whiteflies, blackflies, and aphids. They’ve even been proven effective against root-knot nematodes. Mosquitoes and wasps are also deterred by their strong scent, while African marigolds in particular are said to repel pests like spider mites. They’re even believed by gardeners to be effective against squash bugs and tomato worms. Other than insects, this flower can keep deer and rabbits away from your garden as well. However, they attract slugs, snails, and thrips, so placing them away from other valuable edibles and plants can be beneficial.
Marigolds contain an essential oil that acts as a natural insect repellent called thiophene. Additionally, some pests like whiteflies are deterred by the limonene in marigolds. Another benefit of this flower is that it will attract valuable pollinators to your vegetable garden, making them a welcome addition. If you use marigolds as a trap plant for slugs and snails, be sure you visit them in the evenings to remove these pests by hand.
