Marigolds
Marigolds brighten up any garden with their golden blooms, but they also contain pyrethrum, a natural compound used in many insect repellents. Their strong scent deters mosquitoes, whiteflies, and aphids. Marigolds grow easily from seed, require full sun, and bloom throughout the warmer months. Plant them along garden borders, around patios, or near vegetable beds to keep pests at bay. These flowers also help protect tomatoes and peppers by warding off harmful bugs. Best of all, marigolds are hardy, drought-resistant, and perfect for beginners. Their vibrant color and ability to keep mosquitoes away make them a must-have for any pest-conscious gardener.
